Engine
Make: Cummins / Deutz / Detroit diesel / Equivalent Diesel Engine
Speed Regulation: Through electronic governor
Electrical system: 24 V DC
Compressor

Make: MAK / GHH-RAND / equivalent
Type: Oil free screw compressor with integrated step up gearbox
Flow rate: 100/180/270/300/400 PPM at suction pressure
of 14.5 psia suction temperature of 68°F (20°C)
Discharge pressure:
40 psig at a discharge temperature of 392°F (200°C)
Coupling System

Coupling Flexible with integral housing.
Regulation: Electro pneumatic
Variable flow and a constant pressure of 2.76 bar (40 psig)
are achieved by control of engine speed and the output
air through a pressure regulating valve
This makes the ASU versatile and universal in its applicatio
to be able to start all aircraft requiring
up to 100/180/270/300/400 PPM for starting

Mode Setting: Air Start / AC Pack
