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 an integrated step-up gearbox
Flow rate: 100/180/270/300/400 PPM at a suction pressure of 14.5 psi suction temperature of 68°F (20°C)
Discharge pressure: 40 psi 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 application to be able to start all aircraft requiring up to 100/180/270/300/400 PPM for starting.

 
Mode Setting: Air Start / AC Pack
