AL-KO FLEX UNIT D cartridge filter systems

For powerful dust extraction: AL-KO FLEX UNIT D units are suitable for the extraction and separation of fine dusts in almost all manufacturing processes. Four standard variants offer the right extraction performance for many applications. Thanks to modular system technology, additional individual versions, for example for larger air volumes, are possible at any time. All system components are installed in a housing made of insulated panels. This ensures low operating noise and minimal heat loss when installed outdoors.

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 D systems extract dust and fine particles in numerous industrial and skilled trade production processes. The 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.
