Operating principle

The construction of the systems is based on the time-proven AL-KO standard with soundproof housing panels. They enclose the system and provide for high-performance and quiet operation. AL-KO FLEX UNIT F systems are designed for extraction of fumes that occur during welding, cutting and separation processes. Large-surface filter cartridges effectively filter out the dust, and the filtered exhaust air can either be returned to the hall or released into the environment. The systems are suitable for indoor and outdoor installation.
