The type A47 air starter is generally used for starting internal combustion engines of an approximate range of ratings of 1100 to 4400 kW (1500 to 6000 HP), although the suitability engine depends, in practice, on the engine capacity, number of cylinders and the ratio of the driving pinion to the flywheel ring gear.
The A47 is usually supplied with pinion and flange and does not need external lubrication. It is lubrication-free.
Its high torque and resistance to adverse atmosphere conditions (saline, humidity, extreme temperature) make it the most reliable starter to install in: power plant gen-sets, gas turbines, propulsion engines, heavy-duty diesel engines.
It is also available in the ‘Z’ version to fit in reduced spaces.
