Air Compressor Glossary

Compressor Types

Pancake Compressors
Flat storage tank mounted under the pump. Smaller footprint.

Hot Dog Compressors
Single horizontal tank mounted under the pump

Twin-stack Compressors
Two cylindrical tanks usually mounted under the pump. Adds additional air without increasing foot print.

Wheelbarrow Compressors
Two cylindrical tanks usually mounted behind the pump. Wheelbarrow design allow easy mobility

Power Source

Plug into mains power to fill the tank. Lower maintenance and quieter. Suitable for indoors or close to mains. Not recommended for outdoor use.

Uses petrol to power pump. Suitable for outdoor use. More powerful, producing greater PSI

Units of Measurement

Pounds per square inch.
This is the value of the pressure a gas or liquid exerts on the walls of its container.

The bar is a metric unit of measurement for pressure
1 bar = 14.5038 PSI

Horsepower (HP)

Horsepower or HP  is the power rating of engine or motor.
The higher HP will create more air pressure, which we measure in PSI.
A higher PSI gives more air in the tank.

CFM (Cubic feet per minute) and SCFM (Standard cubic feet per minute)
This is the volume of air that’s delivered at specific PSI.
