in compressor element (E). Compressed air and oil are
discharged to air receiver/oil separator (AR) via check valve
(CV). In the oil separator compressed air is separated from the
oil. The air is blown via minimum pressure valve (Vp) to air
cooler (Ca). The cooled air is discharged through moisture
trap (MTa) and outlet valve (AV) towards the air net.
Check valve (CV) prevents blow-back of compressed air.
GA/GA W 200 up to -315
Air drawn through filters (AF) and unloaders (UA1 and UA2)
is compressed in compressor elements (E1 and E2).
Compressed air and oil are discharged to air receiver/oil
separator (AR) via check valves (CV1 and CV2). In the oil
separator compressed air is separated from the oil. The air is
blown via minimum pressure valve (Vp) to air cooler (Ca).
The cooled air is discharged through moisture trap (MTa) and
outlet valve (AV) towards the air net.
Check valves (CV1 and CV2) prevent blow-back of compressed
air.
All GA/GA W
Minimum pressure valve (Vp) prevents the receiver pressure
from dropping below a minimum pressure. The valve has a
built-in check valve.
1.3.2 Condensate drain system
A moisture trap (MTa) is installed downstream of the air cooler
to prevent condensate from entering the air outlet pipe. The
trap is provided with a float valve for automatically draining
condensate (Daa) and with a manual drain valve (Dma).
1.3.3 Oil system
GA/GA W 90 up to -160
Air pressure forces the oil from receiver (AR) through oil
cooler(s) (Co), filters (OF) and valve (Vs) to compressor
element (E) and the lubrication points.
