Remove the intake filter element from the housing

Clean the intake filter element in one of the following ways

▪ Hand washing: Soak and agitate element in a warm water and mild detergent solution. Allow adequate time for the element to air dry (24 hours minimum). Do not install a damp element. This will cause higher initial pressure loss and rapid dirt loading

▪ Compressed air cleaning: Using approximately 7 bar(e) (100 psi(g) or 5.25 Torr(e)), direct air flow at inside of element towards pleats. Blow off the outside of the element directing the air flow down to avoid embedding dirt in the media. Blow off the inside again to remove any dirt that might be on the clean side of the element

▪ Vacuum cleaning: Point the vacuum cleaner to the dirty side (outside of element) only, using a vacuum of approximately 100 mbar(a) (75 Torr(a)). A crevice tool is recommended

▪ Hand cleaning: Hold element down with one hand and move other hand across the fins in a strumming motion. This action will dislodge most of the dirt

The element is ready to be reused;
