Trouble Shooting a Reverse Air Dust Collector
Is there power in and out of timer? Yes / No
Are isolation dampers sealing properly? Yes / No
Is reverse air fan running? Yes / No
Is reverse air fan rotation correct? Yes / No
Is cleaning cycle set at manufacturer’s specifications? Yes / No
Is cleaning interval set at its shortest interval? Yes / No
Turn on power and/or repair timer.
Adjust and/or repair and check differential pressure
Turn on and check differential pressure
Change motor leads and check differential pressure
Change setting and check differential pressure
Change setting and check differential pressure
Did you pull a filter bag and run a permeability test to check for blinding? Yes
Is filter bag blinding? Yes / No
Analyze for cause of blinding and correct; Replace filters and check differential pressure.
Is air/cloth ratio less than 6:1 if pulse-jet, 4:1 if Plenum Pulse, or 3:1 if reverse air or shaker? Yes / No
Is material being continuously removed from hopper? Yes / No
Contact BPS for further recommendations.
If pulse-jet or plenum pulse, consider pleated media conversion. If reverse air or shaker, consider pulse-jet conversion or increasing collector size.
Remove material continuously and check differential pressure.
