Operational data to be recorded could include measurements taken of the air flow 

rate and the pressure differential across the cartridges. This should be recorded weekly or 

monthly. This record can assist with maintenance schedules and show collector variances 
due to operations. 

 

Maintenance data to be recorded should include details of inspections and any parts 

replaced.  

 
See final page of IOM for Maintenance Interval Checklist. 

 

The  following  maintenance  intervals  are  recommendations  by  AAF,  your  dust 

collection system may need more or less frequent maintenance plans.  

 

12.2

 

 Initial Weekly Maintenance 

This should be done during the first month of initial collector operation.  

 
Record the differential pressure across the cartridges at start-up. Record the collector 

differential pressure regularly for at least the first 30 days of operation.  

 

Adverse operating conditions can be detected by a change in differential pressure. 

The differential pressure can be read on the display of the pulse controller. After start-up, 

the dust collector’s differential pressure should settle to approximately 2-3 inches w.g. 

 

The  filter  cleaning  cycle  is  automatically  controlled  from  the  pulse  controller  with 

either the differential pressure set points or the timed interval used to maintain a steady 
pressure differential across the filter. 

 

Do  not  be  alarmed  if  cleaning  pulses  cause  momentary  spikes  in  the  differential 

pressure readings. 

 

NOTE: The time interval between pulses is factory pre-set at 30 seconds. It may be 

changed  and  is  dependent  on  the  application.  Effective  cleaning  is  reliant  upon  pulse 

frequency, duration and pulse compressed air pressure. The pulse duration is pre-set at 100 
milliseconds. DO NOT change the factory setting without contacting an AAF International 

representative.  
 

Inspect  the  dust  disposal  equipment  on  a  regular  basis  during  the  first  month  of 

operation to determine that the collected dust is being disposed at a rate consistent with 
the operation. Failure to ensure that the collected dust is taken away at the appropriate 

rate will result in material building up into the hopper and could cause malfunction. This is
