Cleaning filters 

 

Access 

Ensure AOF is switched off and isolated prior to opening 
the cover. 

To gain access to the pre-filter and main filter you will 
need to open the clasp on the front end of the AOF and 
open the filter housing. 

 

Depending on installation you may need to remove the 
flexible pipe from the unit first by removing the quick 
release Jacobs clamp located on the inlet to the AOF. 

 

 

Once the unit is open you now have access to both 
internal filters which will need to be cleaned at least once 
every 3 months to ensure system efficiency. 

Ensure P.P.E is worn when opening the AOF filter housing 
and handling filters. 

 

 

 

Pre-Filter 

The pre-filter can now be removed by gently pulling on 
the foam filter to separate it from the main filter. 

To clean 

 Wash the filter through with a degreaser or 

detergent ensuring you remove as much oil/coolant and 
swarf as possible from the filter. 

These should then be left overnight to allow them to dry 
before fitting back into the AOF.
