6.0 Dust Collector – Troubleshooting Cont’d

Trouble

Probable Cause

Remedy

High differential pressure.

Clogged filters.

Screen clogged/dirty.

Check filter pulsing rate and
pressure. Pressure should
be 80 PSI and drop about
30 PSI for each pulse
occurring once every 10 -
11 seconds. Do not allow
dust bin to overfill.

Filters old and saturated –
replace filters.

Clean/replace screen
located inside filter
chamber.

Pressure loss.

Pressurized air leak.

Goyen diaphragm stuck
open.

Unloader valve not holding
pressure.

Compressor not building air
properly.

Timer board malfunction.

Check all high pressure air
connections.

Check solenoid valves’
operation. Replace if
necessary. Check
diaphragm(s). Clean or
replace if necessary.

Adjust or replace unloader
valve.

Repair or replace
compressor. Check air
hoses for leaks.

Check “tell-tale” lights on
timer board, replace if
necessary.
