Pneumatic starter motors
Proven reliability in explosive and offshore environments.
New to pneumatic starting? Read our guide on how an air starter works.
Powerstart pneumatic starter motors, also known as air starters, crank diesel and gas engines using stored compressed air, with no reliance on batteries or an electrical supply. That makes them a dependable choice wherever reliable starting matters most: oil and gas, marine, mining, power generation and fire pump applications.
Our Jetstream range uses a cast iron air turbine design for high cranking torque and long service life, and we supply both turbine and vane air starters to suit different engine sizes and duty cycles. Every unit is designed and manufactured in the UK, with ATEX and IECEx options available for hazardous and potentially explosive areas.
Whether you are specifying a starter for a new engine build or replacing an existing air starter motor, our team can match the right model to your engine make, bore and available air pressure.
