Air Starter Motors: Reliable Starting Power for Heavy Equipment 2025

Air Starter Motors: When it comes to starting large diesel engines or heavy-duty industrial equipment, few solutions are as rugged, reliable, and explosion-proof as air starters. At MultiTorque, we specialise in supplying and servicing air starters across industries like mining, oil and gas, marine, and heavy transport. With more than 15 years of experience and a reputation for long-term client relationships, our team knows exactly what you need to keep your equipment running smoothly.

In this article, we’ll cover what air starters are, how they work, the advantages over electric alternatives, and why MultiTorque is Australia’s trusted partner for air starter supply, servicing, and support.

What Are Air Starters?

Air starters are mechanical devices used to start internal combustion engines—especially in heavy industrial machinery. Unlike electric starters that rely on a battery or generator, air starters use compressed air to initiate engine rotation. This makes them ideal for environments where explosive gases may be present or where battery-based systems are impractical.

They are commonly found in:

Diesel engines on mining and earthmoving equipment
Gas turbines
Generators
Offshore and marine engines
Petrochemical plants
Oil and gas drilling rigs

The design and application of air starters make them a critical component in any industry where downtime can mean a loss in productivity or safety risks.

How Do Air Starters Work?

Air starters work by directing compressed air into a turbine or vane motor, which then generates the torque needed to turn the engine’s flywheel. As the flywheel spins, it initiates the engine’s combustion cycle, starting the engine.

Two main types of air starters exist:

Vane-type air starters: Known for simplicity and high torque at low speeds.
Turbine-type air starters: Ideal for high-speed engines, requiring less maintenance and offering longer lifespan.

Both types are rugged and reliable, and the choice between them depends on your specific engine and environment.

Key Advantages of Air Starters

Here’s why air starters are often the preferred option in industrial applications:

1. No Risk of Ignition

Because they don’t use electrical currents, air starters are non-sparking and ideal for hazardous environments where flammable gases or vapours are present.

2. High Torque Output

Air starters generate instant torque, enabling them to start even large, high-compression engines reliably.

3. Durability & Longevity

Air starters are built to last, with fewer moving parts than electric starters. This means less maintenance, reduced wear and tear, and higher uptime.

4. Lightweight Design

Despite their heavy-duty performance, air starters are compact and lightweight, making them easier to install in tight engine compartments.

5. Fast Restart Time

Because they rely on compressed air, restarts can be immediate—especially valuable in emergency or high-frequency-use scenarios.

Air Starter Applications Across Industries

At MultiTorque, we support clients across a wide range of industries that rely on air starters to keep their operations moving:

Tips for Air Starter Maintenance

Even the most rugged equipment benefits from regular care. Here are some quick tips for maximising the lifespan of your air starter:

Use clean, dry compressed air: Moisture or contaminants can wear down internal parts.
Inspect regularly for leaks: Air loss can cause poor starting performance.
Schedule routine servicing: Preventative maintenance avoids costly downtime.
Replace worn parts early: Components like vanes and bearings wear naturally over time.

MultiTorque offers preventative servicing packages for clients wanting to avoid reactive repairs.
