The SMOGHOG is a free standing, self contained,
multistage, oil mist filtering unit with inlet sump or direct
mount flange, mechanical prefilter, primary filter, blower
cabinet, and controls. Optional after filters are available
for third stage filtration.
2.2 EQUIPMENT DESCRIPTION
This section will briefly describe each component in the
SHM and its role in the system’s operation.
Inlet Sump
Most units will include an inlet sump with multiple 10˝
inlets where all incoming dirty air will enter. The sump
provides an expanded volume allowing contaminant to
drop out of the airsteam reducing loading on the filters. A
1-1/2” FNPT coupling is included at the peak of a sloped
bottom allowing the collected contaminant to be reclaimed
or drained.
Filter Cabinet
Each unit has a filter access door that provides access
to both the prefilter and primary filter for service and
replacement. The mesh prefilter rests on tracks near the
bottom of the cabinet. The PEACH coalescing filter option
are mounted on a removable cassette secured by a cam
bar mechanism. The fiberglass bag option uses a hanging
rod system.

3. INSTALLATION
3.1 INSPECTION AND OFF LOADING
As soon as your equipment arrives, it should be carefully
inspected to make certain that it is in good condition and
that all items listed on the packing list have been received.
Even though the items are carefully loaded and tied
down at the time of shipment, it is possible for them to be
damaged or become dislodged in transit.
Report any damage(s) and/or shortage(s) immediately. It
becomes increasingly difficult for either the carrier or the
supplier to assume responsibility for any damages after
too much time has elapsed. Check all loads separately.
The following steps should be taken immediately
upon receipt of your shipment; this will assure and
expedite claim payments and replacement of missing or
damaged items.
1. Begin your inspection of the shipment BEFORE it is
unloaded.
2. Check for damage to any exposed items, particularly at
the tie‐down locations.
3. Photograph any damage. Do this BEFORE the
equipment is unloaded.
4. Check Bill of Lading quantities and description. Note
any discrepancies on all copies of the Bill of Lading
and have them acknowledged (the carrier should sign).
Damage description should also be written directly on,
or attached to, the Bill of Lading, and should also be
signed by the driver.
Contact the insurance company and the shipper at once
so that damages and/or shortages can be corrected and a
claim can be filed without delay.
TIP OVER HAZARD
Lift the SHM unit and components by the packing
skids or on the lifting eyes located on the top of the
unit in each corner. Do not lift the unit by placing
lift truck forks through the legs on the underside of
the unit.
Filter Elements
Stage 1: Mist-Stop fine fiber aluminum mesh
Stage 2: Primary coalescer featuring PEACH®Saturated
Depth Coalescing Technology - or - fiberglass bag
Blower Cabinet
Most units will have a blower cabinet where the motorized
impeller style blower is housed, as well as the electrical
controls.
2.3 PRINCIPAL OF OPERATION
The purpose of the SHM is to collect fugitive mist generated
by various industrial processes during operation. The
collected contaminate is drained off of the coalescing
filters into the sump below or directly back into the
machine. The sump is attached to a drain system of the
customers choice for recycling or disposal, or emptied
manually at regular intervals.
Do not let the oil level in the sump reach the height of
the air inlet opening.
Differential Pressure
Differential pressure, also referred to as pressure drop
(Δ P), is an indication of the resistance to airflow across
the filter elements. Differential pressure is commonly
measured in inches of water column (W.C.) or Pascals
(Pa). It is normal for the differential pressure to increase as
the collector operates. Any sudden increase or decrease
in differential pressure may indicate a problem in the
collector (blinded filters, leaks or other cause) that requires
immediate attention. See trouble shooting guide in Section
6 for assistance.
The operating differential pressure displayed on the
unit will typically run between 0.5 to 4 in. W.C. (124 to 995
Pa) for a Fiberglass Bag filter, and between 0.75 to 4 in.
W.C. (187 to 995 Pa) for a Coalescing Cartridge filter. The
expected pressure range for the after-filters is 0.5 to 3.0
in. W.C. (124 to 746 Pa).

3.2 INSTALLATION PREPARATION AND
PLANNING
Prior to the actual installation of the SHM, the location
should be readied. This would include having an adequate
laydown area for all components, and access for the
crane, forklifts and other machinery. The unit will come
pre-assembled. The majority of installation will be electrical
hook-up, and hanging, mounting, or securing the unit. An
electrical source, lighting and other equipment should be
readily available to aid in the installation.
In most cases engineering drawings of your specific
equipment and options will be provided. These and
all available documentation for your system should be
thoroughly reviewed prior to beginning any installation
work. This includes the unit and electrical controls. Ensure
to leave an appropriate amount of room around your
unit to allow for maintenance and servicing. A minimum
of 2-1/2 feet (0.76 m) of clearance is recommended for
service in front of the filter access door and 3 feet (1 m)
for the rear electrical access per NEC.
Ensure there is adequate access to the electrical
components with ducting installed.
3.3 DISCHARGE COMPONENT
INSTALLATION
Ensure to position the unit so that the clean air discharge
is directed into an open area free of obstructions and with
consideration for personnel safety.

3.4 MECHANICAL INSTALLATION
CRUSH HAZARD
Use adequate safety measures when lifting and
assembling any heavy components. Consult your
plant safety personnel for recommendations.
Connect lifting slings and spreader bars to lifting lugs
with clevis pins. Use spreader bars to distribute the
load evenly. Location must be clear of all obstructions,
such as utility lines or roof overhangs.
When the SHM unit is to be mounted directly to a
machine, you will be furnished with a mounting flange and
drawing to illustrate the bolt pattern and hardware required
for proper mounting to their equipment. Be sure to seal
around the entire perimeter between the mounting flange
and the existing machine with an appropriate sealant in a
figure-eight pattern around each bolt hole.
Units with sumps utilize 10˝ inlets and optional collar
flange(s) that come mounted to the unit. They can be
rearranged and mounted however desired based on
application needs. Be sure to use a polyurethane sealant
or gasket to prevent leaks. It is recommended to use
ducting that is liquid tight to prevent leaks.
All other transitions, ducting or plenums required for
unit set-up and operation are not included with the
equipment.
Unit should always be secured to the floor when
installed in this configuration.
Secure the unit at all four corners using the standard
unit feet or extension leg foot pads. At least one of the
two holes per foot pad on the extension legs should be
secured. See Figure 1 for reference.
Ceiling mounted units are suspended by means of 1⁄2˝
threaded rods (item #1 in Figure 3) which run through
weld nuts (item #2 in Figure 3) in the top corners of the
units. Refer to Figure 2 for weld nut locations on SHM-11
models. Additional support should be used for auxiliary
equipment or ducting. Do not suspend units larger than
the SHM-11 from the ceiling.
CAUTION
The SMOGHOG should not be used for support of
personnel or material. Check with local building code/
structural engineer to ensure proper installation to roof
truss or any other mounting method.
Metal Truss Supported Ceilings. Figure 3 shows an
SHM-11 unit suspended from a metal truss supported
ceiling. Customer should take care to determine that the
truss will be sufficient to support the weight. As shown,
angle iron braces are secured between two steel trusses.
Rod length should be kept to a minimum and cut to length
as necessary.
FIGURE 3
Ceiling Mounted Unit
In this instance, the rods instead will be installed in the
exact same fashion into the weld nuts found in the blower
cabinet.
Be sure rods are threaded adequately into weld nuts,
about 1˝ (25.4 mm) of rod extending inside the cabinet is
acceptable.
Tighten lock nuts (item #3 in Figure 3) in place to be sure
unit does not vibrate lose or fall over time.

3.5.3 ELECTRICAL TOUCHSCREEN
CONTROLS
The main control panel for the SHM unit is a touchscreen
interface located integrally on the front of the unit or
remotely in an auxiliary enclosure (refer to section 3.5.4)
that operates the blower.
The touchscreen control panel is powered by 24V DC.
Refer to Section 4 of this manual for operation of the
touchscreen. All wiring in the touchscreen controls panel
is pre-wired at the factory and there are no customer
connections at this panel. The panel door should remain
closed and locked during operation.
3.5.4 ELECTRICAL REMOTE PANEL
CONTROLS
Both the Basic and Touchscreen Controls can be
mounted remotely from the unit. The max distance is
100 FT (30.5 m). The controls are provided in a NEMA 4X
enclosure for mounting.
Basic Controls – The remote controls panel/enclosure will
contain the blower speed adjusting potentiometer inside
the enclosure, and an on/off switch on the cover. This
enclosure will be attached to the SHM unit at the factory
with 50ft of wire. The cable can be cut down in length at
the time of installation if needed by disconnecting the wire
from the remote panel, cutting to length, and reconnecting.
Use the wire diagram on page A2 for reference.
Touchscreen Controls – The remote touchscreen controls
enclosure will contain the touchscreen and terminal blocks
for the wire connections. There are two cables connected
to the remote enclosure that are 100ft each. One is the
24 VDC power supply and control cable, and the other
is a communication cable. These wires will need to be
connected to the rear control panel of the SHM unit by the
customer at the time of installation. The first wire is the
low voltage controls wire that will connect to the terminal
blocks in the back of the SHM unit on +24VDC, -24VDC,
AN2, AN3, AN4, I0, and O0. Use the wire diagram on page
A6 for wire colors and terminal location for landing. The
second wire is a communication wire that needs landed in
the WAGO 222 Lever Wall Nuts. Match the colors of the
wires, brown with brown and black with black.
3.5.5 MACHINE INTERLOCK DRY CONTACT
The customer has the option to control the SHM On/
Off operation with the oil mist generating equipment or
process. This will allow the operator to control the SHM
with a dry-contact off another piece of equipment. Refer
to the wiring diagrams in the appendix for wiring of this
option and to Section 4 for Machine Interlock set up on
the touchscreen.
Wiring will be terminated to the terminal blocks located in
the rear electrical panel in Figure 1B When the machine
dry contact is closed, the SHM blower will be on and when
the contact is open, the SHM unit blower will shut down.
Note: A relay coil cannot be connected to the SHM and
will not work for this type of electrical circuit.
3.6 FILTER INSTALLATION
The primary filter elements are shipped already installed
in the SHM unit. If an after-filter option is selected by the
customer, those filters will be shipped separate of the unit
to be mounted following unit installation at the customer
facility. Filters may removed from the primary filter cabinet
by the customer when delivered to lessen weight, protect
them from damage, and ease unit installation.
Proper removal and installation of each filter type is shown
in figures 5A & 5B.
3.6.1 INSTALLATION PROCEDURE FOR
AFTER-FILTERS
3.6.1.1 HOLD DOWN
Center the filter(s) atop the unit when viewed from the
front. If the unit is two filters deep, then the two after-filters
will be butted against each other in the center of the unit
(looking at it from the side) from front to back just as with
the internal filters.
The hold-down brackets are to be placed on top the filters
as shown in Figure 5A balloon #7 and secured down with
all-thread rods, washers and nuts. Tighten nuts using
hand tools and be sure not to over compress the gasket
on the bottom side of the after-filter. Minimal torque should
be applied; just enough to cinch down each bracket so it
will not slide around on top of the filter(s). On units two
filters deep, a center bracket is also supplied that runs in
the same direction, it is placed immediately over the seam
where the two filters are butted together.
Larger size unit after-filter setups will be installed in an
identical fashion. The filters will always be installed in-line,
directly over the perforated square cutouts on the top
panel.

3.6.1.2 ENCLOSED
For units with an after-filter cabinet/enclosure, the after-
filters must be installed into this cabinet. The box-shaped
after-filter slides into the cabinet door on the cam-bars.
Be sure the filter(s) is pushed all the way to the back of
the cabinet where it will bottom out on a stop. Rotate the
cam-bars upward as illustrated in figure 5B. This will seal
the filter’s top mounted gasket onto the cabinet’s upper
tube sheet.
3.7 DRAINS
All SHM units are supplied with 1-1⁄2˝ FPT drain
connections. A 1-1⁄2˝ drain trap or similar to prevent air
from being sucked up through the drain when unit is
running.
NOTES: Main drain line should be sufficiently sloped and
vented. All plumbing should conform with all
state and local codes.
Appropriate design criteria as provided by a plumbing/
mechanical contractor should be utilized to ensure
proper control of drainage from the SHM Unit.
4. UNIT OPERATION
4.1 START-UP
Before system start-up, verify that the installation is
complete per Section 3 of this manual. The following
are the basic steps to walk you through as you are
starting up.
1. Open the SHM filter access doors and verify that the
filters are in place and properly sealed.
2. Close and latch all access doors and electrical
enclosures on the unit.
3. Ensure that the main power is connected and
turned on.
4. Ensure that all circuit breakers are switched on.
5. Follow Section 4.3 for setting changes on the touchscreen
to target the desired airflow volume. Adjust the blower
speed to the RPM % that will provide the targeted
airflow. For assistance in determining the target RPM,
contact your local representative. When using the
Auto Flow option, follow the Auto Flow Settings in
Section 4.
6. Press the blower power button on the Home screen
to begin operation. Note that if the oil mist collector is
connected to a process, other equipment will need to
be engaged as well.
7. Verify performance of the system by measuring
airflow or evaluating capture at each collection point.
It is recommended to record baseline performance
parameters so the system can be reset in case of an
upset condition or system change. The recorded data
should include:
• the static pressure at each collection hood
• system amperage draw and filter pressure drop at a
minimum
• any other key pieces of data critical to your process.
8. To optimize system performance and extend filter life,
run the unit at the minimum airflow required to control
the process.
4.2 SYSTEM OPERATION
As the SHM collects contaminate, a layer builds up on
the outside surface, causing an increased pressure drop
through the filters. As the differential pressure rises, the
blower RPM will need to be increased in order to maintain
the desired airflow. When the filters are saturated, the
contaminant drips to the bottom of the unit and collects
within the oil sump where it can be drained and disposed
of. When the system can no longer generate the airflow
required to capture or convey the collected contaminate,
the filters must be replaced.
4.2.1 AIRFLOW ADJUSTMENT USING
MANUAL SPEED CONTROL
The SHM features an Electronically Commutated (EC)
blower that is equipped with airflow adjustment using
the blower RPM. To adjust the airflow, the blower
speed (RPM) percentage can be adjusted from 20 to
100%. As filter pressure builds, it may be necessary
to increase the RPM to maintain proper capture and
transport velocity within the hood and duct system.
The adjustment of the RPM is done in the Blower display
screen.
4.2.2 AIRFLOW ADJUSTMENT USING
AUTO-FLOW CONTROL
With the Auto-Flow feature, the SHM will automatically
adjust the RPM of the blower to maintain the airflow set-
point. When the system can no longer maintain airflow, a
warning will be provided on the touchscreen. In the event
of a warning or failure on the touchscreen, refer to the
troubleshooting section of this manual to help determine
the cause and associated solution.

4.3.3 BASIC SCREENS
Filter Screen:
Figure 7
The Filter screen can be displayed by the operator by
selecting the filter status icon on the Home screen shown
in Figure 7. The Filter screen will then be displayed with
all available filters. This screen will display the differential
pressure across the filter during operation.
Blower Screen:
Figure 8
The standard blower screen will display the status
of the blower. If your equipment is equipped with the Auto-
Flow option and it is activated, the Blower screen will look
different than that shown in Figure 8. Refer to section
4.3.4 for additional details. The only time the blower
will shut down is when the blower has an internal fault.
Such faults as: Low line voltage, phase to phase issues,
ground issues, temperature issues, or for a catastrophic
failure. If the blower shuts down, refer to Section 6 for
troubleshooting.
On the blower screen you are able to adjust the speed
of the blower using one of two different methods. The
first adjustment can be done using the up/down arrows.
This adjustment will achieve a change of +/- 1%. This will
increase or decrease the airflow adjustment by 1% for
each touch of the up or down arrows.
The second method of airflow adjustment is to touch the
box that shows the percentage of the airflow. A number
pad will be shown in a pop up screen. You can enter any
number between 20 and 100. This will correspond to the
percentage of blower capability. The blower is capable
of 4,200 RPM at 100%, 3150 RPM for 75%, 2100 RPM
for 50%, and 1050 RPM for 20%. These number are
approximate and may display slightly differently on any
given unit. There is a minimum set point for speed which
is 20% for the purposes of the blower design. The SHM
may have multiple blowers incorporated within the system
to support performance of the unit depending on the
customer application. All of these blowers will respond in
unison with the SHM’s controller.
Information Screen:
Figure 9
The information screen will provide a phone number
for customer service. There is also a web address for
our website that can be used to locate your nearest
representative.
4.3.4 AUTO-FLOW SCREEN
Figure 10
When Auto-Flow is installed and activated the blower
screen will look like Figure 10. Refer to section 4.3.6 to
activate the Auto-Flow option and to make adjustments to
your flow target. The Auto-Flow blower screen will show
the target flow, the actual flow, the blower speed, and
the % of total speed available. The screen will also show
blower status. If there is a warning or fault, refer to the
troubleshooting section for guidance.

4.3.5 AFTER-FILTER
Figure 11
When the screen is active you will see the differential
pressure across the filter. The system will monitor this
pressure and give warnings and faults as the differential
pressure changes. The after-filter does not get cleaned by
the system and has a finite life based on the pressure drop
across the filter. When the pressure drop increases to a
point that the filter can no longer provide proper airflow,
the fault symbol will appear. You will need to replace the
filter at that time.
4.3.6 CUSTOMER SETTINGS
The standard customer settings screen shown in
Figure 12 will allow the operator to make General Settings
changes without a password. The Locked Settings will
require a password to be entered. The default password is
4440.
Figure 12
The General Settings selection will allow the operator
to change the units and check service of the major
components like the blower. These settings are not
password protected. To select one of the items just touch
the box with the item you want to make a change too.
The Locked Settings selection will allow the operator
to select options of the system. One option is Machine
Interlock. With Machine Interlock the operator can allow
another device (CNC machine center, plasma table, or
weld machine) to turn the SHM on when the primary
device is in operation. When this option is selected (see
Figure 20) the Blower Power button in Figure 6 will put
the unit in standby when touched by the operator. When
this setting is selected the indicator to the right side will
change from OFF to ON and turn green.
Figure 13
When After‐Filter and/or Auto‐Flow options are ordered,
they will appear on the Customer Settings screen as
shown on Figure 13.
Figure 14
When the units selection is made on the Customer Settings
screen, you will see the screen as shown on Figure 14.
Figure 15
The operator can select the Service settings shown here.
Each of the selection will allow the operator to see the
health of the unit. You are also able to see any pending
alarms and the alarm history for your system using the
buttons provided.

Figure 16
The service hours will allow the operator to see how
long the primary filter and the after filter have been
in service. These hours are resettable by holding the
specific button and holding it until the number resets to 0.
The operator can also see the total number of hours the
SHM has been in service since being built at the factory.
During factory testing the units are quality checked and
may show a low amount of hours such as 1 or 2 from
this test.
Figure 17
The blower service screen will show all of the connected
blowers in the system. The display will show the
communication of the blower. The communication is setup
at the factory and will not need any service in the field.
This is only an indication of the unit for troubleshooting
purposes. The display screen will show the motor
temperature and the blower operating RPM.
Figure 18
The Auto-Flow Settings screen can be selected in the
Locked Settings group on the Customer settings screen.
The Auto-Flow is an option that is selected at order time
and loaded into the SHM at the factory. The Auto-Flow
Settings will allow the unit to maintain a precise operating
point based on a desired air volume. The operator will
select an air volume setting in the airflow set point box
using the up/down arrows or the selection box. If the
screen is changed, the blower will shut off. Once the
operator has found the air flow setting that gives their unit
the best performance they can touch the Auto-Flow ON
and then accept and lock the settings by touching the lock
button at the bottom of the screen.
Figure 19
The After-Filter setup screen can be selected in the
Locked Settings group on the customer settings screen.
The after-filter is an option that is selected at the order
time and loaded into the SHM at the factory. The after-
filter can be monitored by the unit using its controller to
monitor the health of this filter. The operator can select the
monitoring on this screen by touching the After-Filter ON
box and then locking the settings by touching the Accept
and Lock box.

5. SERVICE
Before servicing equipment:
• Wear appropriate protective equipment when
servicing oil mist collector.
• Disconnect and lockout electrical power to the unit
and control panel.
5.1 GENERAL MAINTENANCE GUIDELINES
Proper maintenance of the SHM is essential for the unit
to provide excellent oil mist collection capabilities and
long‐term service. By keeping the unit well‐maintained,
you will also reduce operating and parts replacement
costs. A scheduled preventive maintenance program,
specifically designed for the SHM and its associated
components, is the best possible method to ensure the
unit stays in proper working order.
Refer to Section 6 for troubleshooting guide to correct
any problems that may occur with your oil mist collection
unit. If the problem or condition continues, contact UAS
customer service for assistance.
5.2 FILTER SERVICE
Automatic filter replacement warnings should display on
units so equipped.
On unequipped units, when the primary filters reach the
point of not being able to maintain proper unit function
they must be replaced.
To order filters, contact your UAS sales representative.
Identify your filter part number from your sales order, your
unit nameplate, or the inside cover of this manual.
The aluminum mesh pre-filter can be washed and rinsed
with a moderately powerful spray from a power-washer or
hose. This filter can be replaced if contaminants become
impossible to remove or due to excessive wear.
Always wear proper PPE including goggles, dust mask
and work gloves when installing or replacing filter
elements. Oil accumulated on the filter elements can
result in irritation of the lungs, skin, and / or eyes.
Remove used filter elements from the collector and dispose
of properly, in accordance with governing restrictions. Be
sure there is no excess oil or residue build-up inside the
primary filter cabinet. Clean or rinse as necessary. Inspect
all filter sealing cam bars and filter support parts for
unusual signs of wear or failure. Checking all gaskets and
seals is recommended at this time, as well as replacement
if necessary.
The surface of the filter element can be damaged as a
result of improper moving or handling. Care must be taken
to prevent any damage to the filter media.
Inspect each filter element for damage from shipping,
storage or handling. Do not use damaged elements, they
may leak or fail prematurely.
Review installation procedures for filter elements before
beginning the installation procedures and accessing the
oil mist collector. Follow the proper lockout, tagout.
Numbers in Figure 5 coordinate directly with numbering
below.

5.2.1 INSTALLATION PROCEDURE FOR
PEACH®SATURATED DEPTH FILTER
ELEMENTS
Inspect filters to verify there is no damage and all packing
materials have been removed. A supportive piece of foam
may be inside the filter tube and should be removed
before operation. Be careful upon removal not to pull too
aggressively to dislodge the inner-most end cap.
Set the header plate (balloon #3 in Figure 5A) on the floor
and place a cartridge in the center of each hole. Lift the
header plate up until the top flange of each cartridge rests
on the plate. Slide the filter assembly onto the cam-bar
and into the cabinet while the cam-bar is in the lowered
position (balloon #4 in Figure 5A) (both handles down)
until the filter bottoms out on a stop. Once the entire
cassette is inserted into the cabinet verify that each filter is
sitting straight and fully seated in each header plate hole.
Rotate the cam-bars upward as illustrated in balloon #5 to
push the filter up and seal it against the tube sheet.
5.2.2 INSTALLATION PROCEDURE FOR
PRE-FILTER & BAG FILTER
The pre-filter and primary bag filter must be slid into and
out of their respective tracks in a delicate and uniform
fashion to avoid damage to the filter or jamming inside
the tracks.
Be sure the bag filter is slid into place prior to hanging the
individual bags/loops.
For units that are two filters deep, be sure to push the first
filter all way toward the back of the primary filter cabinet
until it contacts the stop. Reference balloon #1 in Figure
5A.
The hanging rod is to be inserted through each filter loop
and hung from a bracket on each side of the primary filter
cabinet. Work from the back of the cabinet toward the
front.
Center the filter on each rod, and each rod on its
respective bracket.
Verify all bags are hung and supported properly before
securely closing and locking each door/latch. Reference
balloon #2 in Figure 5A.
5.3 CONTAMINANT REMOVAL
Drain the sump regularly. The required frequency of this
action will be dictated by the load rate and operation.
Be sure oil is not accumulating in any location that could
cause malfunction or a safety concern including, but not
limited to, the motor cabinet, filter header plate, and tube
sheet panel.
Be sure to dispose of, or recycle, any waste oil properly.
Dispose of waste in accordance with applicable local,
state, and federal regulations.
