What is an Oil-Free Screw Compressor?

A screw compressor is a type of air compressor that powers twin-shaft rotating lobe machines. They work on positive displacement principle with internal compression and are so-called compulsive conveyors. There are different types of rotary screw air compressors, such as oil-injected screw compressors and oil-free screw compressors. Others include direct and belt-driven.

Oil-free options do not use oil when it comes to compressed air. In other types of compressors, oil is injected to seal rotors, offer lubrication or provide water cooling, air cooling, etc. In this model, AERZEN uses precision and excellence to create an oil-free option of the highest quality.

What are the Key Benefits of Oil-Free?

Rotary screw air compressors without oil offer manufacturers a huge range of benefits everywhere. Those benefits include:

Less Impact on the Environment - The world is racing to reduce oil use to prevent its negative impact on the environment. This model offers higher quality results with a more positive environmental footprint. Not only is less oil being used, but the disposal of oil is no longer a concern.
Lower Cost of Ownership - Maintenance costs are reduced with an oil-less compressor. From oil changes to filters, the cost to maintain the machine at optimal function is less work for your team.
Energy Efficiency - Screw compressors without oil are more energy efficient in the long term.
Reduced Contamination Risk - The risk of contamination is lower with oil-free compressed air systems, helping to ensure products remain clean across industries with strict standards like food and beverage, pharmaceuticals, etc.
And More - The list does not end there. The key benefits of oil-less compressors are endless.
