Good To Know
Q: How often should this air filter kit be replaced? A: Replace it when the restriction indicator signals blockage or at the interval specified in your equipment manual, typically every 500 to 1000 hours depending on dust exposure.
Q: Can I clean and reuse these filters? A: The outer filter may be cleaned with compressed air briefly, but the inner safety filter should always be replaced; both filters lose efficiency after repeated cleaning.
Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
