Chicago Pneumatic OF Series Oil-Free Screw Air Compressor
An oil-free screw air compressor compresses air with no oil in the compression chamber, so the air it delivers carries no oil at all. The Chicago Pneumatic OF Series is a range of oil-free rotary screw compressors certified to ISO 8573-1 Class 0 — 100% free of oil, aerosols and other contaminants. For industries where even a trace of oil would spoil the product or fail an audit, that certified purity is essential.
The OF Series covers 20 to 220 HP in both fixed speed (OF) and variable speed (OF…V) models, delivering up to 825 cfm at pressures up to 10 bar. World-class oil-free rotors, precision gears and superior air-end bearings keep efficiency high and the total cost of ownership low, while the Airlogic controller and ICONS remote monitoring keep the machine reliable. For oil-tolerant duty, compare our standard screw compressors; for the lowest energy cost, the iPM range.
RR Enterprise supplies, installs and services the full OF Series. Pair the compressor with air treatment and AIRnet piping for a complete clean-air system, and ask about the Warranty Service Package covering maintenance for up to 5 years.
What is ISO 8573-1 Class 0 Air?
ISO 8573-1 is the international standard that grades compressed-air purity by oil content. Class 0 is the cleanest grade — even more stringent than Class 1 — meaning the air is certified 100% oil-free. Chicago Pneumatic OF Series compressors are Class 0 certified, so there is zero risk of oil contamination reaching your product or process.
| Class | Total Oil (aerosol, liquid, vapour) mg/m³ |
|---|---|
| 0 | As specified by user/supplier — more stringent than Class 1 (CP OF Series) |
| 1 | < 0.01 |
| 2 | < 0.1 |
| 3 | < 1 |
| 4 | < 5 |
Why Choose the Chicago Pneumatic OF Series
VSD Models Save ~35% Energy
Because energy is around 70% of a compressor’s 5-year operating cost and most plants have fluctuating demand, the OF Series variable speed (V) models match air supply to demand and cut energy cost by an average of about 35% versus fixed speed — while still delivering certified Class 0 oil-free air.
