About FlensTech
FlensTech GmbH develops and supplies point extraction systems and filter systems for capturing harmful emissions such as gases, vapors, smoke, dust, aerosols, ozone and nitrogen oxides. The solutions are used wherever pollutants are generated during production steps such as welding, soldering, gluing, painting or 3D printing – in particular during plasma and corona discharges. The product portfolio includes extraction arms, extraction tables (BZ), filter systems of the FlensAir series (FlensAir-1, FlensAir-3 GF-PP, FlensAir-3L), extraction hoppers with magnet as well as precisely matched piping systems made of spiral-wound ducting with around 3,000 variants. The systems can be ordered directly in the online shop; many items are available from stock and are delivered within 3–5 working days. FlensTech is a subsidiary of Tantec Vertrieb GmbH; the solutions are based on decades of experience in plastics processing and mechanical engineering. The company works with partners such as Gram Clean Air, Ventur, Lindab and Vaupel as well as with research institutions, and supplies exclusively registered companies and educational institutions.
