PRQ-22i Inertia Drive

Turbine Starters

PRQ-22i Series Inertia Drive Turbine Starter

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.
