About Absaugtechnik Kalkhof e.K.
Absaugtechnik Kalkhof e.K. from Unna specializes in individual solutions in extraction, filter and dust removal technology. The company implements direct capture of airborne contaminants at production facilities and workplaces where occupational safety and air quality control are the focus. The range of services extends from project planning and system design through explosion protection concepts, plant engineering and sales of extraction and filter systems to service, maintenance and modernization of older systems - including third-party manufacturers' equipment. The product range includes extraction tables (TC 700, TMFI, DAF, UD, UD2, TAMA) with integrated ventilation and filtration, central high-vacuum vacuum systems, mobile suction systems, dust removal systems, industrial vacuum cleaners, capture elements such as extraction arms and hoods, as well as fans and filter media. Customers come, among others, from the cement, metal and chemical industries as well as from workshops, laboratories and mechanical and plant engineering. The company was founded by Dipl.-Ing. Martin Kalkhof and is today led by owner Michael Heitkamp; it builds on more than thirty years of experience in workplace air quality control.
