2.2 DESCRIPTION AND OPERATION
The DUST-HOG®Supra-Conic®is a high-efficiency,
cartridge dust collector designed for intermittent-duty
collection. The Supra-Conic®is equipped with a filter
cleaning system developed by UAS. The cartridge filter
is a conical filter with an integrated air distribution insert.
The filter is arranged in a vertical orientation to
precipitate contaminant release from the pleated filter
design. The dust collector is designed for automatic
downtime filter cleaning by means of a built-in
compressed air system (refer to Figure 2).
There are two primary modes of operation — the air
filtering operation and filter cleaning cycle (refer to
Figure 3).
2.3 AIR FILTERING OPERATION
The Supra-Conic®is a compact, high-efficiency, vertically
orientated dust collector equipped with a cone-shaped
cartridge filter. The unit includes a backward-inclined fan
wheel for quieter operation and higher airflow
performance, as well as a self-contained air pulse
cleaning system designed for downtime cleaning.
The contaminated airstream enters the dust collector
through the rear and/or side inlets. The airstream
velocity is reduced and channeled by a series of inlet
baffle plates which produce even dust loading distribution
across the conical cartridge filter(s). The conical shape
of the filter provides increased media surface area along
with an inherently lower pressure drop across the filter.
This allows greater external static pressure capabilities
and requires less horsepower (kilowatts) to run. The
filter media strips the dust from the airstream allowing
only the clean air to pass through the filter. The clean
airstream then moves through the tubesheet into the
lower blower chamber compartment which houses a
Goyen®diaphragm valve. The clean airstream is pulled
upward through a backward-inclined blower wheel and is
exhausted out the top of the cabinet.
2.4 FILTER CLEANING CYCLE
During normal operation of the intermittent-duty dust
collector, the surface of the cartridge filter(s) becomes
loaded with contaminants. Upon start-up, the downtime
filter cleaning system will automatically engage and the
air manifold is pressurized to 93 PSIG (6.5 BAR) by a
self-contained air compressor. However, the air pulse
blast does not activate until the unit is shut down. One
minute after the fan is deactivated, the diaphragm valve
will discharge 93 PSIG (6.5 BAR) of air into the center of
the conical filter for 0.5-1.0 seconds. The flexing of the
filter media and the pulse airflow breaks the collected
particles from the filter media and the particles fall
downward into the dust drawer, drum or pail. The
tapered design of the conical filter allow gravity to aid
particle removal and increase dust release.

4.1 INSPECTION NOTE
Upon receipt of your unit, check for any shipping
damage. A damaged carton indicates that the equipment
may have received rough handling during shipping that
may have caused internal damage. Notify your delivery
carrier and enter a claim if any damage is found.
4.2 OFF LOADING AND INSPECTION
Each Supra-Conic®unit is shipped completely assembled
on one skid. Another skid will contain the hopper/leg
assembly and other components. Other accessories
(afterfilters, assemblies, casters, storage drums, etc.)
may be on an additional, separate skid.
Hopper overall dimensional information can be found in
Figures 11, 12 and 13 in Section 7 of this manual.
Supra-Conic®dust collectors have high centers of
gravity due to the unique fan design. Extreme care
should be used when moving the collector to avoid
overturning the unit.
NOTE: Do not lay collector on its side or back as
damage to fan assembly may occur.
4.3 INSTALLATION PLANNING
Asolid, level surface is required for installation of a
standard Supra-Conic®dust collector. Acollector with
optional hopper assembly requires a level concrete

7.1 for additional information on optional hopper
assembly installation requirements.
The Supra-Conic®dust collector is designed for indoor
operation and location only. The Supra-Conic®is
designed to operate at a maximum indoor temperature
environment of 100°F (38°C).
The built-in air compressor is designed to operate in
a light-duty environment. Heavy or dirty environments
will cause the air compressor to malfunction and/or
fail prematurely. In heavy or dirty environments, it is
recommended the customer provide compressed air
to the dust collector manifold.
Locate the Supra-Conic®dust collector as close as
possible to the dust source.
Certain items should be considered when locating the
unit, such as room to empty the dust storage container(s)
(dust drawer, drum or pail), filter removal requirements,
electrical connections and fan discharge direction. The
shortest duct length with a minimum number of elbows
will maximize the performance of the unit. Ease of
maintenance should also be considered when selecting
the location and orientation of the system.
Do not locate dust collector near dust source in cases
where dust is explosive or a fire hazard.
Supra-Conic®dust collectors are not designed as
explosion proof and/or spark resistant units.

4.5 STANDARD DUST COLLECTION
CONFIGURATION
The Supra-Conic®dust collector is designed to allow
collected particles to be bulk stored in three model
configurations: dust drawer, drum/pail or open bin.
4.5.1 DUST DRAWER ASSEMBLY
The dust drawer configuration is standard on all Supra-
Conic®models. The dust drawer package consists of a
dust drawer(s), bottom filter housing panel and fasteners.
The individual dust drawers have a collection volume
capacity of 1.8 cubic ft (51 liters). The SC600 and
SC1700 are equipped with a single dust drawer and the
SC3400 is equipped with two dust drawers. Dust drawer
configured Supra-Conic®models are shipped fully
assembled from the factory. Field installation for dust
drawer assembly is not required. The bottom filter
housing panel is removable to allow for upgrading the
collection method to a hopper or caster assembly
configuration in the field.
4.5.2 HOPPER ASSEMBLY
Pail and drum configured Supra-Conic®units require a
hopper assembly. The hopper assemblies are shipped
separately from the Supra-Conic®unit and require field
assembly. For hopper installation instructions, refer to
Section 7.1. Figure 9 highlights the method necessary to
mate the hopper assembly to the Supra-Conic®module.
4.5.3 BIN VENT ASSEMBLY
The Supra-Conic®dust collector may be configured from
the factory for a bin vent application. The bin vent
package allows the Supra-Conic®module to be
configured with an outboard flange around the base of
the filter housing. The bin vent configuration requires
field assembly. The outboard flange plate is shipped
loose along with fasteners for connecting the outboard
plate to the Supra-Conic®inner base flange. A dimension
sheet and installation instruction drawing are provided
with the bin vent package.
4.6 DRUM LID KIT INSTALLATION FOR
HOPPER ASSEMBLIES
Remove the drum lid kit package from its shipping
carton. Place the drum lid on the 5-gallon (19 liter) pail,
30-gallon (114 liter) shortened drum or the 55-gallon
(208) liter drum. Slide the 8" (20cm) or 14" (36cm) hose
over the drum lid and secure with a hose clamp.
Position the drum assembly over the unit, slide the hose
onto the discharge adapter collar on the hopper and
secure with a hose clamp. Slide gates are factory
installed at UAS when this option is ordered. Open the
slide gate prior to using the dust collector.
NOTE: The hopper is not designed for dust storage.
The slide gate should remain open during
normal operation.
4.7 INLET COLLAR AND BLANK COVER
PLATE INSTALLATION
Inlet collar and blank cover plates bolt directly to the
Supra-Conic®dust collector housing. Inlet collar
assemblies are specified with the initial order. If inlet
diameters and locations are not specified with the initial
order, the dust collector is supplied with all blank cover
plates.

Shut off the disconnect panel and lock out all electrical
power to the dust collector before performing any
service work.
Loosen check valve (white plastic part) connected to
brass tee threaded into air manifold reservoir to
completely relieve air pressure prior to performing any
service work on the air pulse cleaning system (refer to
Figure 8).
The Supra-Conic®dust collector is supplied with a self-
contained air pulse cleaning system which has been
factory installed by UAS. The air pulse cleaning system
consists of the following major components: air
compressor, diaphragm valve, pressure switch with
unloader valve, check valve, interconnecting tubing and
fittings, air manifold reservoir, printed circuitboard
controller card, and conical filter assembly. The air pulse
cleaning control system requires 500 watts of 100-120V,
single-phase, 50/60 hertz power supply to operate.
The dust collector may be configured without a built-in air
compressor, in which the customer is to supply the clean,
dry, oil-free compressed air to the air manifold reservoir.
!WARNING
5. OPERATION
5.1 START-UP
Never operate dust collector without the blower
compartment bolt-on panel being installed.
Shut off unit disconnect and lock out all electrical
power to the dust collector prior to performing
service work.
UNIT BLOWER (FAN)
Inspect the installation area and make certain no tools,
parts, etc. have been left anywhere on or inside the
Supra-Conic®dust collector. Check blower discharge to
make certain it is free from all debris.
Start motor/blower and check for proper rotation. A
rotation arrow is located in the blower compartment
beside the fan wheel. All blower wheels rotate in a
clockwise rotation as viewed from the driven end (motor
end with motor cooling fan). If the blower is rotating in
the opposite direction, disconnect the power to the motor
starter. For 3-phase power, interchange any two power
wires to the motor at the load side of the motor starter
contactor (for single-phase power, refer to motor
nameplate for which two wires to interchange at motor
junction box), engage starter disconnect, start blower
and recheck rotation.
NOTE: Proper blower rotation is required to move the
designed amount of air. A blower rotating in the
incorrect direction will only move about 40% of
design airflow and cause the fan motor to pull
excessive running load amps. Running blower in
incorrect rotation for an extended period of time
will cause fan motor damage and reduce life of
motor/blower.
PC CONTROLLER BOARD
The Supra-Conic®dust collector is equipped with a
printed circuitboard (PC) controller card which controls
the air pulse cleaning cycle. Refer to Figure 7 for PC
board layout and fuse information.
The PC controller card is equipped with four board LED
lights which can be seen through the electrical enclosure
lid. The four LED lights indicate the following conditions:
FAULT – Activates after a pulse valve or pressure
switch failure
PULSE – Indicates when pulse valve is energized
SYSTEM – The LED continuously illuminates to indicate
the air pulse cleaning system has been
energized.
The LED flashes to indicate the pulse cycle is
sequencing, allowing the pulse valve to
activate.
COMPRESSOR – Indicates the compressor is running.
