● Tee-type air filter - used to remove any particulate contaminates from
the system. A multi-layered glass fiber element produces high effi-
ciency silt-control filtration and provides for extended service intervals
and reduced maintenance cost.
A visual pressure indicator enables the operator to read contaminated
build up before the element is plugged, with an automatic reset.
● Two electrically-controlled open/close air shut-off valves.
● Pressure safety relief valve, set at 165 PSI (11.4 BAR).
● Pressure safety relief Rupture Disc, set at 350 PSI (24 BAR).

centrate and air.
