Nearly 50 years later, we are proud that our great passion has made us the world's leading provider of smoke extraction and innovative ventilation systems. We will continue to inspire confidence with innovative solutions that provide a safe, healthy and comfortable atmosphere in buildings. We call it: Building Atmosphere.
