Process owners/operators have important responsibilities relating to combustible hazards.
Process owners/operators must determine whether their process creates combustible dust,
fume, or mist. If combustible dust, fume, or mist is generated, process owners/operators should at a
minimum:
• Comply with all applicable codes and standards. Among other considerations, current NFPA standards
require owners/operators whose processes involve potentially combustible materials to have a current
Hazard Analysis, which can serve as the foundation for their process hazard mitigation strategies.
• Prevent all ignition sources from entering any dust collection equipment.
• Design, select, and implement fire and explosion mitigation, suppression, and isolation strategies that
are appropriate for the risks associated with their application.
• Develop and implement maintenance work practices to maintain a safe operating environment, ensuring
that combustible dust, fume, or mist does not accumulate within the plant.
Donaldson recommends process owners/operators consult with experts to insure each of these
responsibilities are met.
As a manufacturer and supplier of Industrial Filtration Products, Donaldson can assist process owners/
operators in the selection of filtration technologies. However, process owners/operators retain all
responsibility for the suitability of fire and explosion hazard mitigation, suppression, and isolation strategies.
Donaldson assumes no responsibility or liability for the suitability of any fire and/or explosion mitigation
strategy, or any items incorporated into a collector as part of an owner/operators hazard mitigation strategy.
Improper operation of a dust control system may contribute to conditions in the work area or facility that
could result in severe personal injury and product or property damage. Check that all collection equipment is
properly selected and sized for the intended use.
DO NOT operate this equipment until you have read and understand the instruction warnings in the
Installation and Operations Manual. For a replacement manual, contact Donaldson Torit.
This manual contains specific precautionary statements relative to worker safety. Read thoroughly and comply
as directed. Discuss the use and application of this equipment with a Donaldson Torit representative. Instruct all

Standard Donaldson Torit equipment is not equipped with fire extinguishing or explosion protection systems.
The Dalamatic Cased, Model DLMC, dust collectors
are continuous-duty collectors with bag-style filters
designed to handle product recovery applications and
operations generating nuisance dust. The DLMC provides
continuous filtration and high collection efficiency while
maintaining a relatively constant system resistance.
Standard sizes range from 323 to 5164 sq ft (30 to 480 sq
meters) of filter area. A solid-state timer provides the
interface for filter cleaning control.
Options include a pyramid hopper for use with a
55-gallon drum or rotary airlock, a trough hopper for use
with a screw conveyor, or hoppers for use with bin-style,
dust disposal pails.
The DLMC separates solid particulate from an airstream
as part of a manufacturing process.
The DLMC is commonly used in the chemical, mineral,
food, plastic, metal compound, and pharmaceutical
industries. High temperature applications are possible
with attention to gaskets, caulking, and filter media
choices. Extreme conditions may require special paint
and structural modifications.
Although primarily designed for negative pressure
systems, the DLMC can be used under positive pressure.
Contact Donaldson Torit for information on positive
pressure systems.
Description Purpose and Intended Use
Misuse or modification may result
in severe personal injury and/or
property damage.

During normal operation, dust-laden air is drawn through
the dirty air inlet. Dust will hit the baffle causing the dust
particle velocities to be reduced. From there, natural pre-
separation, caused by the effects of gravity, takes place
with larger particulate falling directly to hoppers and fine
particles collecting on the outside surface of the filter.
Clean, filtered air passes to the center of the filter and
discharges through the clean-air outlet.
Filter cleaning is completed using pulse-jet technology.
A jet tube positioned over each filter distributes a pulse
of compressed air through the filter. As the compressed
air enters the filter, airflow is temporarily reversed
dislodging the dust cake formed on the outside of the
filter. The dust cake falls into the hopper and exits
through the hopper outlet.

Compressed Air Requirements
2 Tier Collectors 55-psig
3 Tier Collectors 65-psig
4-8 Tier Collectors 90-100 psig
1. Remove the plastic pipe plug from the collector’s air
manifold and connect the compressed-air supply
lines. Use thread-sealing tape or pipe sealant on all
compressed-air connections.
2. Install a customer-supplied shut-off valve, bleed-
type regulator with gauge, filter, and automatic
condensate valve in the compressed-air supply line.
3. Set compressed-air supply pressure to a level
suitable for the filters (90-psig). The pulse-cleaning
controls are factory set to clean one or more filters
every 10-seconds during a cleaning cycle.
Compressed Air Installation
Turn compressed air supply OFF,
bleed and lock out lines before
performing service or maintenance work.
A safety exhaust valve should be used to
isolate the compressed air supply. The safety
exhaust valve should completely exhaust
pressure in the collector manifolds when
closed, should be capable of being interlocked
with fire or explosion mitigation equipment
and should include provisions to allow closed-
position locking.
Do not set compressed-air
pressure above 100-psig as
component damage can occur.
All compressed air components must be sized
to meet the system requirements of 90-100-psig
supply pressure.
Compressed air pressure must be set to
the pressure listed in the Compressed Air
Requirements table to ensure proper operation.
The compressed-air supply must be oil
and moisture free. Contamination in the
compressed air used to clean filters will result
in poor cleaning, cleaning valve failure, or poor

Donaldson Company, Inc.
Electrical installation, service
or maintenance work during
installation must be performed by a qualified
electrician and comply with all applicable
national and local codes.
Turn power off and lock out electrical power
sources before performing installation, service,
or maintenance work.
Do not install in classified hazardous
atmospheres without an enclosure rated for
the application.
Solid-State Timer Installation
The solid-state timer is used to control the filter cleaning
system.
Solenoid Connection
The collector is equipped with electric solenoid valves
(typically 120V) that controls the pulse-cleaning valves,
which in turn clean the filters.
Solenoid enclosures are mounted near or on the
collector’s compressed-air manifold.
Wire the solenoids to the solid-state timer following the
wiring diagram supplied with the collector. Filter life and
cleaning operation will be affected if not wired correctly.
Timer and Solenoid Specifications
Power to the solid-state timer is supplied to Terminals
L1 and L2, which are intended to operate in parallel
with the fan starter’s low-voltage coil. On fan start-up,
power is supplied to the timer and the preset OFF time is
initiated. At the end of the OFF time, the timer energizes
the corresponding solenoid valve to provide the ON time
cleaning pulse for one diaphragm valve and then steps to
the next until all filters have been cleaned.
To pulse when the fan is OFF, install a toggle switch as
shown on the Solid-State Timer Wiring Diagram. When
the toggle switch is ON, the timer receives power and
energizes the solenoid valves’ pulse-cleaning operation
even though the fan is turned OFF.
1. Using the wiring diagram supplied, wire the
starter, solid-state timer and solenoid valves. Use
appropriate wire gauge for rated amp load as
specified by local codes.
2. Plug the program lug into the pin that corresponds
with the number of solenoid valves controlled.
3. With power supply ON, check the operation of the
timer and valves. The valves should open and close
sequentially at factory set 10-second intervals.
4. If a gauge or similar device is used to control the
solid-state timer, the jumper on the pressure switch
portion of the timer should be removed. The solenoid
valves will then pulse only when the differential
pressure reaches the high-pressure setpoint. The
valves will continue to pulse until the low-pressure
setpoint is reached.
The solid-state timer voltage
must match the voltage of the
rating of the timer provided (typically 120VAC).
Do not mount the solid-state timer directly
to the collector as mechanical vibration can
damage the timer.

Helix Tube Filter Installation
1. Open access door and remove jet tube retainer.
(Retainer is only used on collectors that are 4 tiers or
taller.)
2. Remove jet tubes and set aside. Cover the openings
to the diaphragm valves. To remove jet tube, unbolt
the top of the jet tube from the top.
3. Remove the hex nuts securing the insert clamps.
Remove the clamps and set aside.
4. Starting on one side of the collector, place a helix
tube filter in a seal frame slot as shown Helix Tube
Filter Installation.
Be careful to not scrape the
filters when slipping them
through the seal frame.
5. Install a second helix tube filter adjacent to the prior
helix tube filter.
6. Install a venturi on both adjacent helix tube filters
and place a clamp over one end of both venturis.
Install a nut and tighten using a deep well socket
and extension. See Clamps and Inserts. Do not
overtighten. Maximum recommended torque is
20 ft/lb.
Note: Tighten bottom clamp first.

1. Check that the collector is securely bolted to the
floor or mounting pad.
2. Check that all duct installation is complete and all
removable panels are in place.
3. Check that all hopper outlets are fitted with
containers or closed to prevent airflow from entering
the system through the hopper outlets.
4. Check all electrical connections for tightness and
contact.
5. Check for proper rotation as noted on the fan and/or
hopper discharge device housing.
To reverse rotation, single-phase power supply:
Follow manufacturer’s instructions on the motor’s
nameplate.
To reverse rotation, three-phase power supply:
Switch any two leads on the motor junction box.
Do not interchange a power lead
with the ground wire. Severe
personal injury and/or property damage may
result.
6. Check and remove all loose items in or near the inlet
and outlet of the collector.
7. Check that all remote controls and solenoid
enclosures (if applicable) are properly wired and all
service switches are in the OFF position.
8. Check that all optional accessories are installed
properly and secured.
9. Turn power ON at source.
10. Turn the compressed-air supply ON. Set
compressed-air supply pressure to a level suitable
for the filters (90-psig).
11. Turn fan motor ON.
Do not look into fan outlet to
determine rotation. View the fan
rotation through the back of the motor.
Check that the exhaust plenum is free of tools
or debris before checking blower/fan rotation.
Stand clear of exhaust to avoid personal injury.
12. Turn the Solid-State Timer ON and check that valves
operate in the proper sequence by monitoring the
LEDs on the front panel.
13. Verify operation of interlocks and audible warning
system, if equipped.
Instruct all personnel on safe use and maintenance
procedures.
Electrical work during
installation, service or
maintenance must be performed by a qualified
electrician and comply with all applicable
national and local codes.
Turn power off and lock out electrical
power sources before performing service or
maintenance work.
Turn compressed air supply OFF, bleed and
lock out lines before performing service or
maintenance work.
Check that the collector is clear and free of all
debris before starting.
Do not install in classified hazardous
atmospheres without an enclosure rated for
the application.
Optional fans over 600 lbs must be
independently supported.
Preliminary Start-Up Check
Typical Start-Up Sequence
