(2) (2) Safety el Safety element ement
The safety filter element should never be
cleaned since the safety filter is the last barri-
er to contaminant before it reaches engine/
equipment. The useful life of the safety filter is
equivalent to that of the primary air filter only
if the primary filter element is being regularly
cleaned. If the primary filter element is not
cleaned, the safety filter should be changed at
every third primary air filter change or after
one year of continuous service, whichever
occurs first.
