Opening the range
SK 3237.700
Complete fan-and-filter unit for tool-free installation. Diagonal fan technology keeps pressure stability high and air throughput more constant, so heat leaves the enclosure more evenly. Air throughput 20–1,160 m³/h in the range; IP 54 as standard.
SK 3240.900
Energy-efficient EC fan-and-filter unit with IoT capability. Pleated filter as standard for maximum air throughput. Wide-range 100–240 V for worldwide use. Modbus activation: automatic filter cleaning, filter maintenance display and emergency cooling.
SK 3237.600
