AIR FLOW
Air drawn through the airfilter (AF) into the
compressor element (CE) is compressed. At the
element outlet, compressed air and oil pass into the air
receiver/oil separator (AR/OS).
The check valve (CV) prevents blow-back of
compressed air when the compressor is stopped. In
the air receiver/oil separator (AR/OS), most of the oil
is removed from the air/oil mixture; the remaining oil
is removed by the separator element.
The oil collects in the receiver and on the bottom of
the separator element.
The air leaves the receiver via a flow nozzle (FN)
which prevents the receiver pressure from dropping
below the minimum working pressure (specified in
section Limitations ), even when the air outlet valves
are open. This ensures adequate oil injection and
prevents oil consumption.
The system comprises of a temperature switch (TS)
and a working pressure gauge (PG).
A blow-down valve (BDV) is fitted in the unloader
assembly to automatically depressurise the air
receiver (AR) when the compressor is stopped.
