The new S-Series of oil-free scroll compressors from CompAir does not use any oil anywhere in the compressor and has been certified ISO 8573-1 Class 0 and silicone free, which represents the highest air quality level possible.

In addition to the fulfilment of legal requirements, the oil-free scroll technology reduces the costs of ownership by avoiding oil filter replacements, oil condensate treatment and energy to combat the pressure loss caused by filtration.


100% oil-free design
High reliability
Continuous operation, 100% duty cycle
Energy efficient
Low vibration and sound levels
Compact design
Low maintenance due to less moving parts

Scroll compression explained

An orbiting (rotating) scroll and fixed scroll housing are mated to create the compression chambers.
The continual movement of the orbiting scroll moves atmospheric air from the intake toward the center, compressing the air into progressively smaller areas.
The compressed air is directed to the center discharge port of the compressor

Discharge pressure is accomplished during multiple stages of compression, resulting in a continuous intake suction and discharge.

The S-Series from CompAir is available with different controller options. The Simplex versions can be either equipped with the basic relay panel or optionally with the Deluxe HMI electronic controller.
