About KAWEHA Absaugtechnik

KAWEHA Absaugtechnik GmbH, based in Lohfelden in North Hesse, has been developing and manufacturing customized air extraction and filtration solutions for industrial working environments since 1991. The portfolio includes extraction systems for dusts and solids, for oil and emulsion mist as well as aerosols, for gases and volatile organic compounds, plus special designs and industrial fans. Products include the stationary Oilmaster OM Reverse extraction system with flow rates from 1,500 to 100,000 m³/h and the mobile OILMASTER MINI R ST/M series with 600 to 1,500 m³/h, both featuring 3-stage filtration and a frequency converter. For special machines and particular processes, the company creates individual concepts, including ATEX-compliant filtration systems, spark detection and extinguishing systems, and inert-gas filter extinguishing. The systems are used in, among others, metal processing, the chemical and food industries, plastics processing, and laboratories. Performance is confirmed by measurements from accredited testing institutes; services range from consulting through development, installation and commissioning to maintenance and service.
