Filter fan units FFU and air handling units AHU

FFU and AHU are used in clean rooms to ensure consistently high air purity. FFUs are usually integrated into the ceiling and are used to protect sensitive production processes. Krantz AHUs are customised special solutions, can be equipped with various filter stages, fans, insulation, cooling and heating coils and have significantly higher air volumes than FFUs.

Stabilised stainless steel; space-saving component arrangement; customised filter stage combination

• Fully welded housing from the last HEPA or ULPA stage for food production; splash guard; multi-stage AHU variants; energy-efficient fans, full stainless if required; double-walled insulated housing available
• Applications FFU: semiconductor, microelectronics and wafer clean rooms, pharma, food, laboratories, hospitals and isolation wards; AHU: food industry
• Filling cabin and clean working cabin UltraFlex clean room for the food industry

Laboratory outlet LAB-V

Laboratory outlet with a high volume flow rate to generate a low turbulence room air flow to supply fresh air and protect laboratory personnel, reducing washout effects at fume hoods. Volume flow 700 to 1,700 m³/h; sizes 1,500 and 2,000 mm; maximum cooling load 130 to 190 W/m². Hybrid low-turbulence mixing-displacement ventilation, adaptable to room load. Our demo laboratory room with fume hoods in Aachen is used to analyse laboratory-specific air distribution systems.
