At the heart of every screw compressor is its screw airend whose efficiency and performance translates the performance of the device throughout its service life. ASU screw airends with an optimized rotor profile were designed by specialists from the Research and Development Department of Airpol. The vast experience and knowledge of compressed air technology gained over several decades, as well as professional, modern technical facilities, allowed us to start the production of Polish screw airends a few years ago. Thus Airpol company joined the small group of world manufacturers of screw airends, confirming that it is a specialist in its branch. Precision of manufacturing, low tolerance of measurement accuracy at every stage of production are the guarantee of high quality and durability of ASU screw airends. Our offer includes screw airends with a wide range of applications, from 7.5 kW up to 110 kW motor compressors, made for the pressure range of 5.5 – 15 bar.
