Scheduled service
Change the element at least once a year, or sooner if the differential pressure gauge on the housing shows it is loaded.
Breakdown spares
Keep one on the shelf so a loaded compressed air filter element does not stop the machine while parts are ordered.
Workshop and fleet stock
Workshops looking after several machines can stock this one element under any of its 4 part numbers.
No. It is an aftermarket compressed air filter element made to replace the Walker Filtration E831AC. It is not made by or affiliated with Walker Filtration, and the part number is used only to show what it replaces.
It replaces the element numbered Walker Filtration E831AC and the other numbers in the cross reference table. Check the number on the old element or in the machine's parts list.
Carbon stops adsorbing once it is saturated, whatever the pressure gauge says. Change it at least every 6 to 12 months, or sooner if oil vapour or odour comes through.
Isolate the filter housing and let the pressure out. Unscrew the bowl, pull the old element off its seat, fit the new element with its O rings lightly lubricated, refit the bowl and pressurise slowly. Check for leaks.
