If not using AEON PD synthetic blower lubricant, use
oils with rust and oxidation inhibitors, anti-foam addi-

AIR FILTERS AND FILTER SILENCERS
Servicing the air filters is one of the
most important maintenance opera-
tions to be performed to insure long
blower life.
Servicing frequency of filter elements is not time
predictable. A differential pressure indicator, with a
continuous gauge reading, should be installed across
the inlet filter. It will tell how much of the service life of
the filter element has been used. It will also eliminate
both premature filter servicing and premature blower
failure due to a plugged filter when the filter pressure
drop is used to establish maintenance points.
In all cases refer to the filter manufacturer’s service
instructions. Due to the many types of filters, it is not
practical to give specific instructions covering all
models.
No matter what type of filter is used,
always make sure all seats, gaskets,
clamps and hose connections on the
filter and inlet line are absolutely air
tight. Each time the filter is serviced,
inspect interior of the blower for dirt.
