Ingersoll Rand Air Starters are Made in the USA

Banner image for Turbine Air Starters by Ingersoll Rand - they deliver industry leading performance, reliability, and quality the you can count on.

Ingersoll Rand Turbine Pneumatic Air Starters are built to provide reliable performance under the most demanding conditions. The differences between the turbine motor and the vane motor are significant. The turbine motor is lighter in weight, does not need lubrication, and has a tremendous amount of stored energy. It develops its power at extreme rotational speeds as high as 60,000 rpm. Ingersoll Rand turbine motors are speed limited by design and are insensitive to moisture due to the use of the most modern composite materials. The new ST1000 turbine starter uses a solid aluminum motor and is the class leader in performance and durability.

Because turbine starters develop high torque from a compact, lubrication-free motor, they are the usual choice where duty cycles are punishing and service access is limited. Operators running compressor packages and wellhead engines should start with our air starters for oil and gas selection, while standby and prime-power sets are covered under air starters for power generation. For vessels and offshore platforms — where moisture tolerance matters most — see marine air starters. If you are matching a Caterpillar engine or genset, the fitment guide for CAT diesel engines and gensets lists recommended models by SAE flange and pinion.

Selection & sizing guide

How to Choose an Ingersoll Rand Turbine Air Starter

Ingersoll Rand turbine air starters crank diesel and gas engines from 5 to 320 liters (660 L carbureted) with a lube-free motor. This guide compares every series, shows which engine sizes each covers, and walks through sizing by displacement, cycle, fuel, air pressure and mounting.

Simplified diagram. A turbine starter turns the energy of expanding air into rotor speed, then gears it down to cranking torque. With no rubbing vanes, the motor runs without lubrication.

Ingersoll Rand turbine starters use a fully supported, high-speed rotor (not a cantilever), sealed oil-lubricated planetary gears and a modular motor that shares parts with its vane starters. Because nothing rubs inside the motor, there is no oil in the air supply and the exhaust is clean, and IR rates every current turbine series for extended cranking beyond 10 seconds.

Turbine vs Vane Starters

Turbine startersVane starters
MotorAir expands through nozzles onto a turbine rotorSliding vanes in an offset rotor
LubricationNone in the air supply (lube-free motor, sealed oil-bath gears)Small amount of oil in the air (SS100 is lube-free)
Long crankingRated for extended starting (>10 seconds), except the ST700Not rated for extended starting in IR's selection guide
Power range23 to 70 hp per starter (TS gas-turbine starters to 146 hp)13.8 to 75 hp per starter
Engine range (diesel)5 to 320 LUp to 320 L
StrengthsLight weight for the power, tolerant of dirty or wet air (ST1000 solid rotor)High torque at low speed, simple design, long track record

Both types start the same engines. Choose turbine for lube-free operation, long cranking or dirty and wet air; choose vane for high torque at low speed and a simple, proven design. Many engines in our Model Finder list one of each.

How to Size Any Air Starter

  1. Engine size and cycle. Find the displacement in liters (cu in ÷ 61.02). Ingersoll Rand's ranges are for 4-stroke diesels; for 2-stroke diesels multiply the range by 1.5, and for carbureted (spark-ignited gas) engines double it.
  2. Hard starts. IR's own rule: "For difficult-to-start engines or for operation under adverse conditions, use the next more powerful starter." Think cold climates, heavy driven loads, high compression or long idle periods.
  3. Supply pressure. Use a part-arc model for supplies up to 150 psi and the full-arc ("99") model for low-pressure supplies of 90 psi or less. Check the performance table at your pressure, not just the maximum.
  4. Air or gas. If the starter will run on natural gas, choose a gas-sealed version and pipe the exhaust away.
  5. Engagement. Pre-engaged: the drive pinion is completely engaged with the engine ring gear before the starter begins to crank the engine. Inertia: the rotating drive pinion engages the engine ring gear simultaneously with the initial cranking of the engine.
  6. Mounting. Match the flange, pinion (teeth, pitch, pressure angle) and rotation to the engine, or simply read them off the old starter's nameplate.
  7. Air supply. Make sure the receiver holds enough air for several start attempts at the starter's flow rate (see the calculator).

Frequently Asked Questions

Why choose a turbine air starter?

No lubricator to fill, no oil in the exhaust, light weight for the power, and IR rates its current turbine series for cranking longer than 10 seconds. The ST1000's solid aluminum rotor is designed for harsh, contaminated environments.

What is the largest engine an Ingersoll Rand turbine starter can crank?

The ST1000 (D gear set) covers diesel engines up to 320 liters and carbureted gas engines up to 660 liters. Larger engines use two or more starters cranking together.

What does "arc" mean in a turbine model number?

The share of the turbine fed by the nozzles. Part-arc motors (44, 50, 60%) are for supplies up to 150 psi; full-arc "99" motors are for low-pressure supplies up to 90 psi and make similar power from less pressure.

Can turbine starters run on natural gas?

Most current IR turbine starters are sealed for gas (150T, ST150, ST500, ST1000, ST2000 BG). The ST400 and ST600 are air only.
