The systems of the FLEX UNIT ECO series offer a unique combination of extraction technology and heat recovery in a compact design. They are available in two standard versions: for extraction of dusts and welding fumes.

AL-KO quality:
- Professional extraction and ventilation technology from a single source
- Optimally integrated filtration and ventilation technology in one unit
- Maximum energy efficiency

Operating principle:
AL-KO FLEX UNIT ECO systems combine extraction and filtration technology in the first stage with the downstream ventilation technology in a compact unit. They are available in versions for dusts (FLEX UNIT D ECO) and welding fumes (FLEX UNIT F ECO). Time-proven AL-KO filtration technology separates the extracted dust or welding fumes by means of efficient filter cartridges. The filtered air then passes through a downstream heat exchanger and is released into the environment. The heat exchanger takes about 73 percent of the heat from the exhaust air and mixes it with fresh air drawn in by a fresh air fan before returning it to the workspace.

Applications:
- For hazardous dusts and fumes that are subject to regulations for exhaust air conduction and fresh air supply, for example in the machining and welding of stainless steel
- Extraction in grinding, welding, polishing and other processes
- Direct extraction at machines, welding stations, booths and enclosures

Your benefits:
- Extraction system and heat recovery in one compact system
- Optimal combination of extraction and ventilation technology
