The type S30 air starter has been developed to start internal combustion Diesel and gas enginesfrom a power range of 750 to 3200 kW (1020 to 4350 HP), although the suitability depends, in practice, on the engine capacity, number of cylinders and the ratio of the driving pinion to the flywheel ring gear.

The S30 is usually supplied with pinion and flange and does not need external lubrication. It is lubrication-free.

They are successfully used in: power plant gent sets, propulsion and auxiliary marine engines, emergency generating sets and motor pumps.
