Rotary Screw Air Compressors
L45+ to L132RS
CompAir lubricated rotary screw compressors incorporate the very latest technological advances and guarantee a continuous supply of high quality compressed air.
New CompAir FourCore range balances two-stage efficiency with single-stage footprint
CompAir has announced the launch of its new 110 to 250 kW FourCore compressor range, combining best-in-class compressed air efficiency with a small footprint and sustainable design for eco-conscious businesses.
The FourCore range offers all the capabilities of a two-stage compressor, but with only the footprint of a single-stage unit. It therefore provides businesses – who might not have previously had the on-site space available – the opportunity to take advantage of the capabilities of two-stage technology. And when compared with previous single-stage compressors in this size range from CompAir, the new models are up to 8 per cent more efficient, offering a best-in-class oil-lubricated solution for decision makers.
Our application engineering team, based at the Simmern Centre of Excellence production site in Germany has designed and engineered a brand new, patented technology that offers best-in-class energy efficiency. They have developed a premium efficiency 2-stage model for fixed and regulated speed compressors using the new technology of the compact double stage airend. What’s unique about this design is that the airend has 1 motor and 4 rotors located in a single, semi-integrated casting. This differs from traditional 2-stage compressors, providing a compact package with high energy savings. In fact, these machines are the same size as a 1 stage machine due to new airend technology.
