Choosing an Air Compressor?

Which compressor configuration best suits you?

Choosing the correct air compressor isn't always simple. Purchasing a compressor that is too big can produce higher future costs in electricity and servicing, not to mention potential damage due to a lack of adequate use.

A compressor sized too small and you might not be able to use all of the equipment you need.

If you are unsure of what compressor would be suitable for you, please refer to the below troubleshooting guide

​

Do I need a receiver?

Simply put, yes! Typically any compressor will need some form of a receiver to store compressed air. 

Although most compressors come built complete with receivers, if you already have a receiver that is suitably rated and sized for the compressor you are after, then you can connect straight into this with a base-mounted compressor. 

​

Do I need a dryer?

Most productions rely on good quality air to ensure their end product is free from any contaminants or defects caused by "dirty" or "wet" air. You should consider the potential long-term damage to your equipment and product caused by untreated air when choosing an air compressor. If you already have a dryer that is suitably sized and rated for the compressor you are after, you may be able to connect this into your system.

​

Do I need a three-phase compressor?

Compressors come in many shapes and sizes and often different power supplies. 

If you are limited to single-phase (such as most residential buildings) then you may have no option other than to consider purchasing a single-phase, diesel, or petrol compressor. However, this may limit the amount of free air delivery (CFM) available to you. You should calculate/consult how much free air delivery you require before making a decision. 

Three-phase compressors typically offer much higher output (CFM) but again, you should consider the maximum AMPS your supply is rated for before making a decision. An electrician may be required to assist you with this.

​

Do I need a Piston or Screw compressor? What's the difference?

While Piston compressors offer good reliability, value for money and are typically more maneuverable than screw compressors, most piston compressors are only rated at 50% duty. This means they are not designed for continuous use, and should only be used for applications when compressed air is not used critically in your production. 

Screw compressors on the other hand offer 100% duty cycles and are built to run continuously in a well-ventilated environment. However, if you don't require continuous air delivery, you should consider the potential long-term damage caused by "underusing" a screw compressor. Much like a car, the compressor needs to maintain a minimum temperature when it is running to ensure the oil circulates properly through the compressor and doesn't cause internal damage.
