Anyone who works in a cleanroom understands the complex hygiene procedure even before entering the workplace: protective clothing must be put on. Everything that could contaminate the environment should be covered: shoes, hair and clothing are covered by a hygiene suit. Jewellery is removed, hands are disinfected, and a mouthguard is mandatory. In addition to the personal safety equipment of the users, access to the cleanroom is a critical point. It takes place via locks that are controlled by special doors. The EFAFLEX CR cleanroom series was specifically designed for the requirements of strictly controlled production areas and are used daily in various industries worldwide.
