Local Air Compressors in Sydney NSW

Types of air compressors

There are numerous methods of compressing air, divided into either rotodynamic and positive displacement types. We’ve gathered the more common types of air compression to compare how different air compressors operate.

• Positive displacement works by forcing air into a chamber whose volume is decreased. By decreasing the volume, there is less space for the air, which increases the pressure.
• Common types of air compressors that work this way include piston, rotary screw and vane compressors, which have differing mechanics behind guiding air into the compression chambers.
• Dynamic displacement air compressors are mainly centrifugal compressors or axial compressors. A rotating component uses centrifugal force generated by rapid spinning to accelerate air, which causes the air to be pressurised.

With this in mind, you’ll have a better understanding and appreciation of the intricacies of compressing air. If you’re looking to get some cheap air compressors near you, have a browse through our directory to see all our listings for industrial air compressor suppliers.
