CompAir Oil-Free Screw Compressors

CompAir’s oil-free rotary screw compressors are built for applications where air purity is essential, including food and beverage production, pharmaceuticals, electronics manufacturing, and medical use. J&J Air Systems supplies and services the full CompAir oil-free range UK-wide, backed by expert advice on sizing and installation.

Oil-free technology eliminates the risk of oil contamination in your compressed air, removing the need for additional filtration in critical processes while maintaining CompAir’s standard for reliability and energy efficiency. Get in touch for expert advice on sizing, installation, or servicing.

Choosing a CompAir air compressor for clean-air work

Choosing a CompAir air compressor for a clean-air application usually comes down to how much risk oil carry-over presents. Every CompAir compressor in this range is Class 0 certified, which means no oil in the air stream at all rather than a filtered-down trace.

In food and beverage production that matters wherever air touches product or packaging directly. In pharmaceutical and medical work it is normally a regulatory requirement rather than a preference. Electronics manufacturers specify oil-free to protect boards and optical surfaces from contamination, and the same logic applies to paint and coating lines where a trace of oil ruins the finish.

Sizing an oil-free installation

Sizing matters as much as purity. An oversized machine spends its life loading and unloading, which wastes energy and shortens component life. An undersized one runs continuously and struggles to hold pressure. Tell us your flow in cfm or litres per second, the pressure you need at the point of use, and how demand varies through the shift, and we will size it properly.
