Absolute tightness is a top priority in the requirements profile when dealing with problematic media such as toxic liquids or gases. With an equally high level of care and know-how, REITZ meets all the relevant safety standards.


In order to prevent anything escaping to the exterior and ensure that people and the environment enjoy maximum safety, we equip our gas, liquid and dustproof fans with a sealing system which has proven its effectiveness thousands of times in practical applications. In addition to gasproof welding of the housing, shaft passages and flange connections are equipped with reliable sealing technologies such as the multichamber labyrinth seal and, where required, the barrier gas connection or grease seal.
