Air Flow - Atlas Copco XAMS 407 CD Instruction Manual

AIR FLOW

Air drawn through the airfilter (AFce) into the
compressor element (CE) is compressed. At the
element outlet, compressed air and oil pass into the air
receiver/oil separator (AR/OS).
(AFce)
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 oil collects in the receiver and on the bottom of
the separator element.
The air leaves the receiver via a minimum pressure
valve (MPV) which prevents the receiver pressure
from dropping below the minimum working pressure,
even when the air outlet valves are open (specified in
(CE)
section Limitations). This ensures adequate oil
injection and prevents oil consumption. The
minimum pressure valve (MPV) also functions as a
check valve.
(CV)
The system comprises temperature sensors (TS),
(TS)
pressure sensors (PS) and a working pressure sensor
(WPS).
