About Karl Bleymehl Reinraumtechnik
Karl Bleymehl Reinraumtechnik GmbH, based in Inden-Pier (North Rhine-Westphalia), is a manufacturer of air-handling cleanroom equipment and systems. The company manufactures laminar flow workbenches and aseptic workbenches in several series (ASW-F, ASW-FU, ASW-QR, ASW-UP, ASW-UD) for product, personnel and environmental protection, as well as integrated laminar flow ventilation systems with HEPA filter ventilation for cleanroom conditioning. The focus is on the laminar flow principle, with which airborne particles are extracted in a controlled manner to create ultra-clean working conditions. Applications range from product protection (e.g. aseptic work, PCR technology) to personnel protection (separation of health-hazardous dusts and hazardous substances) to environmental protection. The company was founded in 1980 and, according to its own reference list, supplies customers from pharma, biotechnology, chemistry, medical technology, laboratory and research in Germany and abroad, including BASF, Bayer, Boehringer Ingelheim, Hoffmann-La Roche, Novartis and Forschungszentrum Jülich. Management has been held by Bernd Markus Bertschinger since October 2025; the company is registered under HRB 3566 at the district court of Düren.
