L-RS Series 7.5-22 kW
Fixed & Regulated Speed Rotary Screw Compressors

CompAir-L-AIRstation-rotary_1The L-RS series of fixed speed and regulated speed screw compressors, provide a high quality, reliable, energy saving and compact compressed air solution from 7.5 to 22 kW.

Lower energy costs can be achieved thanks to the new design of the high efficiency airend which operates at low rotational speeds. In addition, the innovative integrated design with; oil-separation, oil filter and thermostatic bypass valve, increases reliability by reducing the number of external hoses and components.

For a complete packaged solution CompAir offers AIRstation. The L series compressor and a refrigerant dryer are mounted onto a high quality air receiver. Simple to use, simple to install and with a small footprint, AIRstation is the ideal “Plug and Play” solution for the smaller compressed air user.
