About Us
Cleanroom Technology Austria GmbH, headquartered in Wiener Neudorf, is an Austrian full-service provider of cleanroom technology. The company plans and builds cleanrooms and cleanroom systems on a turnkey basis with its own production and assembly, and also offers measurement technology for qualifying room air quality as well as maintenance of the systems. Core products are HEPA filter and laminar flow systems, the TAV ceiling OPi-UL developed in-house with full-coverage HEPA filters for operating rooms, and the patented SurgeonAir system; more than 500 OPi-UL systems have been exported, among other countries to Egypt, Russia, Indonesia, Morocco, Sri Lanka and Mongolia. The company's roots go back to the founding of Filter-Service GmbH in 1965; as its successor, CTA can look back on more than 60 years of experience in cleanroom technology. Customers come from the semiconductor industry, pharmaceuticals, medical technology, automotive, healthcare and research, including the Austrian National Bank, the Space Research Institute of Graz University of Technology and Vienna General Hospital (AKH Wien). An engineering office, Czech Engineering GmbH, complements the planning services.
