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
