How Do Single Stage Air Compressors Work?

roatry screw compressor diagram 570x360

In oil-free water-injected screw models, single phase compressors use a rotating helical screw and two symmetrically placed star wheels to compress air. Water injected into the compression chamber absorbs heat, reduces friction, and seals gaps for higher efficiency. After compression, a separator tank divides air and water, with the air discharged and water recirculated within the system.

In oil-flooded screw models, single phase compressors operate by using two interlocking helical rotors that spin in opposite directions to compress air. As air enters the system, it fills the gap between the screw threads or grooves, where it is compressed as the screws rotate. The majority of rotary screw compressors are oil-flooded, where oil is used to seal, lubricate, and cool the compression process. However, oil-free screw compressors are also available for applications requiring contamination-free air.

You May Also Want To Know

The following are frequently asked by our customers about single stage air compressors.

What is a single-stage air compressor?

A single-stage air compressor compresses air in one stroke, where atmospheric air is drawn into a cylinder and compressed to deliver at a set pressure, typically around 90-145 psi.

How does a single-stage compressor differ from a two-stage compressor?

A single-stage compressor compresses air only once, while a two-stage compressor compresses air twice, achieving higher pressure and making it suitable for heavier industrial applications.

What are the benefits of a single-stage air compressor?

Single-stage compressors offer simpler design, lower initial cost, easy maintenance, and are generally more compact, making them a great choice for small businesses or DIY users.

How do I maintain a single-stage air compressor?

For oil-injected compressors, regular maintenance includes checking oil (or water) levels, valves and other spare parts as well as cleaning and replacing filters. Proper maintenance extends the compressor’s lifespan and ensures consistent performance.

What is the maximum pressure a single-stage compressor can achieve?

At Gairs, single-stage compressors typically reach up to 181 psi (12.5 bar), though some models may go higher to 232 psi (16 bar), depending on the application.
