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.
