I wonder about cleaning the filter by blowing it out with air. When I worked in the truck shop that was a big no-no; cause it might make small holes in the media, and it might imbed particles that would drop out into the engine later. For fleets we would send the big air filters out to be washed, dried and inspected. Is air cleaning accepted now to prolong the life of a BHAF?
If no one knows for sure, I could check with the Donaldson tech guys and let the rest of us know.
thanks,
