Donaldson Torit Dust Collector HPH

Warning: Do not let the dust storage containers overfill. It can cause poor collector performance and create an extensive clean up due to overflow of dust when removing the container(s). In addition, it can cause dust to accumulate in the collector hopper. This should NEVER happen.

Turn off the dust collector and empty as necessary. Empty the 55-gallon drum when 2/3 full.

If the hopper has a gate attachment, close the gate before servicing the drum. Remove and empty the drum and open the gate. The collector fan does not have to be shut off if this procedure is followed.

CAUTION: Compressed air can be dangerous.

Before attempting service, shut off plant air supply to dust collector and depressurize air manifold. Disconnect and lock out electric power to dust collector, fan, and rotary valve. Do not operate the dust collector with the inspections or access doors removed.

Check the following items every three-to-four months:

1. Check the condition of the clean air section for dust. There should be no dust accumulations on the tubesheet. If dust is present, check the surrounding filter tubes for rips or loose seals. Shining a light down the center of the tube will usually reveal any dust leaking through the tube.

2. Proper operation of solenoid and diaphragm valves.

3. Check seals on the door and adjust or replace as necessary.;

Warning: This check requires trained personnel with PPE!

Exhaust visibly clean after filter exposure to dust

If a leak develops, report the issue to the maintenance team and stop the procedure

Monitor filter tube pressure drop

Note: 1 to 6 'wg is considered normal for filter tube pressure drop

Fan motor overload at initial start-up with new filter tubes?

If fan motor overload happens, partially close a volume control damper and check blower fan amperage draw.
