Ambient air is cleaned as it is drawn in through the filter
8
.
The air is then compressed in the airend
5
.
The airend is driven by an electric motor
3
.
Cooling oil is injected into the airend. It lubricates moving parts and forms a seal between the ro‐
tors themselves and between them and the airend casing. This direct cooling in the compression
chamber ensures a very low airend discharge temperature.
Cooling oil recovered from the compressed air in the oil separator tank
7
and separator car‐
tridge
10
gives up its heat in the oil cooler
9
. The oil then flows through the oil filter
4
and back to
the point of injection. Air pressure within the machine keeps the oil circulating. A separate pump is
not necessary. A thermostatically regulated fan keeps the cooling oil at optimum temperature.
Compressed air passes through the minimum pressure / check valve
2
into the air receiver
12
. The
minimum pressure/check valve ensures sufficient internal pressure to maintain cooling oil circula‐
tion.
Compressed air is cooled in the receiver and chilled in the refrigeration dryer
11
. Most of the mois‐
ture carried in the air is removed in this way.
