COLASIT is the world’s premier manufacturer of Plastic centrifugal fans for corrosive applications. COLASIT was established in 1944 and was one of the first companies in the world to recognize the potential for fabricating equipment in plastic. These pioneering efforts led to the development of the first COLASIT plastic centrifugal fan – the CMV (COLASIT Medium Ventilator) more than 50 years ago and COLASIT has been setting the world benchmark ever since. COLASIT is constantly striving to improve the design and performance characteristics of their fans taking into account various factors such as energy efficiency, noise levels, longevity and industry needs. This has led to a comprehensive range of proven designs able to cater for air flow volumes from 40m3/h up to 130’000m3/h and static pressures right up to an impressive 7’000Pascal.
