ST155FP88R54-POS Turbine Air Starter | 47 hp | Half Arc (up to 150 psi) | NEW by Ingersoll Rand

The Ingersoll Rand ST155FP88R54-POS is a genuine IR ST150-series pre-engaged turbine air starter. It is a lube-free solid-aluminum turbine starter that delivers up to 47 hp (35 kW) and 240 ft-lb (325 N·m) of breakaway torque at 150 psi. Ingersoll Rand built the ST150 for heavy-duty diesel and gas engines in the 11 to 90 liter size. This ST155 is the half-arc version for 60 to 150 psi supplies. It uses the code 88 drive housing on an SAE No. 3 flange and drives a right-hand 11-tooth 6/8 pitch pinion. The ST150 is the current successor to the 150T "F" series.

How to Read the Model Number

Why Choose the ST155FP88R54?

ST155FP88R54-POS FAQ

What is the opposite-rotation version of the ST155FP88R54-POS?

The ST155FP88L54-POS is the opposite-rotation counterpart. Power, flange and gearing are the same; only the rotation and the matching pinion code differ. Match the rotation printed on your existing starter's nameplate.

What is the difference between the ST155 and ST159?

The ST155 is a half-arc turbine for 60 to 150 psi supplies (47 hp at 150 psi). The ST159 is a full-arc turbine for 30 to 120 psi supplies (47 hp at 120 psi). Choose by the pressure you can deliver at the starter.

Does the ST150 replace the 150T "F"?

Yes. Ingersoll Rand's supersession list moves 150TMPF88/81 models to ST155FP88/81 models with the same suffix, and 150TLPF models to ST159FP models. The ST150 keeps the 150 drive-housing and pinion coding.

Can it crank for a long time?

Yes. IR highlights the ST150's rugged planetary gearing as allowing extended crank cycles.

What does -POS mean?

It means the inlet, exhaust and drive-housing positions are specified when the starter is ordered. Tell us how your ports need to point, or send photos of your installation, and we will configure it.
