Oil-Free Screw Compressors

No Risk of Contamination with Drying Compressors

Are you running a production where there should be no risk of oil contamination to the product? This is where the oil-free air compressor comes in. Also known as a dry screw compressor it ensures that the risk of contamination is eliminated. 

Find out how the drying compressor achieves this below. We also have a range of oil-free air compressors available to suit your needs here. Check them out below.


ALUP's OF Oil-Free Compressor

The dry or "oil free" screw compressor compresses air without cooling the compression chamber. The compressor's operating temperature therefore rises to about 200°C, even at an operating pressure of 300 kPa. 

For normal industrial air pressure (about 700 kPa), the drying compressor must therefore compress the air in two stages and cool the compressed air between the compression stage.

Air compressors are used in many different applications and provide essential compressed air to many businesses and individuals with different air needs. No matter what your CFM, PSI and HP requirements are, the electronic controller on your air compressor is the motherboard for keeping your unit running as efficiently as possible. It is your eyes into your machine.


The emergency stop, "e-stop", is for true emergency situations only. When hitting the e-stop, all power is halted from the machine and the unload process isn't achieved. The emergency stop button is intended to help with possibly hazardous situations that are developing. Common conditions of having to use the e-stop is the misuse of the equipment in ways that weren’t intended, predictable failures not addressed or failing to consider all the foreseeable uses of the compressor.


Air compressors are helpful for an enormous range of applications such as air filling, packaging, tools, HVAC control, and more! One possible drawback is the amount of electricity they use; air compressors can be a huge drain on energy if used ​inefficiently​. If you are running them too long, allowing leaks to exist, or using the wrong type of compressor, you are wasting ​energy and money​. This article will go over some of the biggest power-wasters and how to
stop/prevent them!
