Three nozzle configurations are used on the Series 22 starters where the pressure is considered low at 30 psi to 90 psi; standard pressure from 90 psi to 120 psi and high pressure applications from 120 psi to 180 psi.
The starter drive clutch setting is the main determining factor when choosing the correct starter. If the starter is pressurized beyond its stated pressure too much torque would be created that could damage the starter drive.
The 22 Series turbine requires no lubrication in the air stream, due to the turbine having no rubbing parts; all bearings are lubed for life.
The 22 Series as well as all air starters require clean air, filters or strainers are strongly recommended to prevent foreign object damage to the rotating turbine wheels and stators.
An electric time delay is offered to prevent start attempts in a no start situation before the turbine wheels have stopped rotating
The 22 series is shorter and has a smaller diameter than some competitors starter models; an adaptor is available that allows the 22 series to bolt up to existing exhaust plumbing to facilitate starter change out.
The PRQ-200 comes in both a right & left hand rotation to start counter rotating main power engines.
There is a low pressure model as well as the standard pressure model.
The PRQ-200 Series has an exhaust adaptor that allows direct replacement using certain competitive starter exhaust plumbing with the inlet a direct fit in many replacement situations.
PRQ 200 Series is available in a bearing forward inertia model as well as a bearing forward of the pinion pre-engaged model.
