How to Read an Ingersoll Rand Air Starter Model Number

Every character in an Ingersoll Rand starter model number means something. Here is the SS815GB03R31 vane starter, decoded:

  1. SS8Series: SS800 vane air starter
  2. 15Type: pre-engaged drive (10 = inertia; 15, 25, 50 = pre-engaged)
  3. GGas sealed, for natural gas as well as compressed air
  4. BGear ratio 2.18:1 (C = 2.53:1, D = 3.44:1)
  5. 03Mounting flange: SAE No. 3
  6. RPinion rotation: right hand (L = left hand)
  7. 31Pinion code: 12 teeth, 6/8 pitch, 20° pressure angle
  8. -22GOptional orientation suffix: inlet 2, exhaust 2, drive housing G. It sets port positions, not fit.

Codes differ between series (a pinion code in the 150 series is not the same pinion as in the SS800). Search any number in our part-number index or send it to us for a match.

Vane vs. Turbine Air Starters

Vane

  • Sliding-vane air motor
  • High starting torque at low speed
  • Lubricated in service (SS100 is lube-free)
  • The standard for small and mid-size engines

How an Air Starting System Works

  1. Air receiver

    A tank stores compressed air (or natural gas) at the pressure the starter is rated for.

  2. Strainer & relay valve

    The strainer cleans the supply; pressing start opens the relay valve and sends full flow to the starter.

  3. Air motor

    The vane or turbine motor turns the flow of air into high-speed rotation.

  4. Gear reduction

    Gearing trades speed for torque (the ratio is in the model number).

  5. Pinion & ring gear

    The drive meshes the pinion with the flywheel ring gear and cranks the engine; once it fires, the pinion disengages.

Air Starter Questions & Answers

How many models of Ingersoll Rand air starters do you offer?

We offer every single model of Ingersoll Rand air starter available. There are hundreds of different models of Ingersoll Rand vane and turbine air starters, each designed with features to optimize performance for specific applications, plus air starters designed for special applications and extreme conditions such as high temperatures or rugged environments.

What is an air starter?

Air starters are a robust and secure alternative to traditional electric starters for diesel and gas engines. They operate without batteries and eliminate the risk of sparks, using compressed air to provide superior starting torque. With minimal moving parts, they are built for longevity and ease of maintenance, and they keep performing through vibration, extreme temperatures, dust and saltwater exposure, which makes them ideal for marine, mining, and oil and gas applications.

When should I choose an air starter over an electric starter?

Consider an air starter when you need low maintenance (fewer moving parts than electrical systems), safety in explosive or highly flammable environments (reduced risk of sparks), and adaptability to diverse operating conditions across many industries.

What is the difference between turbine and vane air starters?

Vane air starters use a sliding-vane air motor that produces high starting torque at low speed. They are lubricated in service (the SS100 is lube-free) and are the standard choice for small and mid-size engines. Turbine air starters use a compact turbine motor that is lighter and does not need lubrication, which makes them the usual choice where duty cycles are punishing and service access is limited. Ingersoll Rand's vane and turbine series both reach engines up to 320 liters; see the series table above.

How do I find the right air starter for my engine?

Use our Air Starter Model Finder: choose your engine maker and model to see the matching Ingersoll Rand starters and barring motors. You can also call us at 1-800-353-4676 and our sales engineers will match you with the right starter for your application.

What details do I need to order a replacement air starter?

The engine make, model and serial number; the model or part number of the starter you have now (any brand); the mounting flange (SAE No. 1, 3, 4 and so on); the pinion's tooth count and pitch; the rotation (right or left hand); and the air or natural gas supply pressure. With those, our sales engineers can match the exact Ingersoll Rand model. Request a quote.

How do I read an Ingersoll Rand air starter model number?

Each part of the number is a feature. In SS815GB03R31, SS8 is the SS800 vane series, 15 a pre-engaged drive, G gas sealed, B a 2.18:1 gear ratio, 03 an SAE No. 3 flange, R right-hand rotation and 31 the pinion code (12 teeth, 6/8 pitch). A suffix such as -22G sets the inlet, exhaust and drive-housing positions. Codes differ between series, so decode a pinion code within its own series.

How does an air starter work?

Compressed air (or natural gas) stored in a receiver tank passes through a strainer; pressing start opens a relay valve that sends full flow to the starter. Its vane or turbine motor spins, a gear reduction multiplies the torque, and the drive meshes the pinion with the flywheel ring gear to crank the engine. Once the engine fires, the pinion disengages.

Can you replace an air starter from another brand?

Yes. We offer upgraded replacement pneumatic vane and turbine air starters to replace all brands, including T.D.I., ASC, A/M, Aire-Myte, Start-Master, Pow-R-Quick, Solar, Wahlberg and more. The Model Finder's "Replacing another brand?" tab shows the closest Ingersoll Rand match.

Do you sell parts, rebuilds and repairs?

Yes. Besides new starters, we provide factory authorized repair services, rebuilds, and spare parts for all Ingersoll Rand air starter models, as well as factory remanufactured Ingersoll Rand air starters for customers looking for an economical alternative.

Do you accept purchase orders?

Yes. We accept Net 30 purchase orders on approved credit.

Do you ship outside the United States?

Yes, we ship worldwide. International customers can call us at +1-401-305-7997, Monday to Friday, 9 to 5 Eastern time.
