Dust Collector Maintenance Checklist

1. Record your differential pressure.

Differential pressure measures the difference in pressure between the dirty and clean air sides of the Industrial Dust Collectors. High differential pressure indicates that the filters are creating a lot of resistance. When the differential pressure reaches about 2 KP, Filter Element needs to be replaced.

By monitoring differential pressure regularly, you`ll notice any changes. For example, if differential pressure suddenly drops a lot, you may have a hole in a filter or a leaking gasket. Consequently, this lets air get through more easily by bypassing the filters.

2. Check drums and hopper.

Overflowing your dust collection hopper can create a mess. Worse, it can also seriously damage your Industrial Fume Extractor. Drums must be emptied before the dust reaches the top. Observation window can be added to the dust hopper.

If drums overfill, the dust can back up into the hopper and into the Dust Collector. Firstly, this may damage the filters. Secondly, it creates a dangerous situation where dust could ignite inside the dust collector.

3. Inspect valves and hoses.

Diaphragm and solenoid valves control the pulses of compressed air that clean your filters. These valves can become damaged or leak. This causes a loss of compressed air. It also means that filters may not get cleaned effectively.

Check these valves regularly. First, make sure that when the cleaning system pulses, all the valves work at the same time. Second, make sure that the valves open all the way and close all the way. Check that all hoses are attached and inspect them for leaks.

4. Examine door seals and gaskets.

Industrial Dust Collectors' door has a seal that keeps air and dust inside. This gasket around the edges of the door can become worn out or cracked. If this happens, the door will not seal properly.

Open the dust collector doors and inspect the gaskets. If they appear to be damaged, they should be replaced. Air leaks can allow dust to escape. They can also allow air to be pulled into the dust collector. This can keep the system from moving air properly.

5. Check compressed air pressure.

Pulse jet dust collectors clean their filter with compressed air. This removes dust from the filters to keep them working well. If the compressed air pressure is too low, the pulse jet cleaning system can`t clean the filters efficiently.

If compressed air pressure is too high, filters could be damaged. Check the pressure of the compressed air regularly. It should be at the setting specified in your manual.

6. Lubricate fan bearings.

Check the balance of the air blower impeller, the electric motor axletree (annoit).
