Mak Controls making quality Air Start Unit for over 45+ years of industrial experience, We are expert in manufacturing air start unit for aircraft usages. Air start unit are used for starting aircraft engines equipped with air starter. It supplies necessary quantity of air at specified pressure through one/two or three hoses attached to the aircraft's under belly. https://www.makcontrols.com/index.php/makcon_products/air-starter-unit-asu/

1. Air Start Unit
Air Start Unit equipment to start the aircraft through pneumatic power
with the required airflow and air pressure depend upon aircraft demand
(100 ppm, 180 ppm, 300 ppm, 400 ppm) whenever aircraft Auxiliary
Power Unit is failed / not working condition. We build the variant type of
Air start unit with depending upon client’s aircraft requirement for
transporting the system like Tow able/trailer/skid mounted
/self-propelled
Our Air start unit is tested with B777 Aircraft-engine GE90-115B in a
minute. We are a good achiever in the globe for a manufacturing Air
start unit

2. MAK Air Start unit is available in a standard model that ranges from 90
PPM - 450 PPM. The Air Start unit is a rotary machine comprising of an
oil-free dry Screw Compressor with an integral gearbox and driven by a
suitable Diesel Engine.
These units provide regulated, dry, oil-free air at a pressure of 40 PSIG,
with determined flow required to start the aircraft jet engines, while the
On board Auxiliary Power Unit is Unserviceable.
AIR START UNIT PRINCIPLE OF OPERATION
The Air Start Unit is air compressor package, it consists of various
components and assemblies. The Diesel Engine acts as a prime mover to

3. rotate the secondary Screw Compressor. Other major
components/assemblies are as follows,
 Compressor air suction filter assembly.
 Compressor oil tank and output assembly.
 Output air pressure regulating assembly.
 Electronic control module assembly.
 Pneumatic panel assembly.
 Compressor oil coolers assembly.
 Output header / Hose assembly.
 Engine fuel tank assembly.
 Engine air filter assembly.
 By-pass assembly.
Air Start Unit proprietary digital pressure control system automatically
regulates the output air pressure/flow for different air crafts with low
noise level. To know more information about Air Start Unit visit us
