Fan filter units are flexible and economic solutions to remove particles from the re-circulated air of turbulent or unidirectional ventilated clean rooms.

Fan filter units are stand-alone units with integrated HEPA-filter, fan and control system.

They supply purified air to clean rooms and laboratories within the life-science, food-and beverage and microelectronic industries by removing harmful airborne particles from recirculating air. Unlike pressurized clean room ceiling plenums, FFUs create a positive room pressure that reduces the contamination risk from potential ceiling bypasses.
