Counter-rotating duct fan with high-quality sheet steel housing
The casing of the counter-rotating duct fan is made of high quality sheet steel and powder coated black according to the applicable standards. The fan uses modular impellers made of aluminum hubs and PAG (glass fiber reinforced polyamide) blades.
Motors – asynchronous, three-phase 400V/50Hz or single-phase 230V/50HZ, IP 55, insulation class F, cast aluminum. Three-phase and single-phase motors are suitable for speed control. For high pressures, the impellers are arranged in counter-rotating direct current.
