Cleaning
Prior to cleaning an air filter element, check it for damage and replace element if any damage is found. The element can be cleaned using compressed air but air pressure should never exceed 30 PSIG (200kPa). The element should be cleaned a maximum of six times and it should not be used longer than one year without changing.
When cleaning, reverse flush the element by directing the compressed air up and down the pleats in the filter media from the “clean side” of the element. Continue reverse flushing until all dust has been removed. Replace the element if any oil or greasy dirt remains on the filter surface.
