Rosenberg’s latest innovation in HVAC, ventilation and air filtration fans is being kept super quiet. The new company’s new backward-curved fan can generate1000 CFM of air movement and 1.9” of pressure with only 76 dB(A) of noise (Sound Power – Sound Pressure would be 69 dB at 3 feet.)
Available as a module (part number N43-28003) or as a motorized impeller (part number N42-28002), the fan features Rosenberg’s new 120-V, single-phase 400-watt EC motor coupled with a very highly efficient and exceptionally quiet glass fiber reinforced polyamide impeller. Both models are IP54 rated.
Standard input voltages are 100 to 130 Volt or 200 to 277 Volt, single phase in 50-60 Hz frequency. Like all Rosenberg EC motors, the new motor runs cooler and more efficiently, while increasing airflow. CE-approved and ErP compliant with an excellent FEI, it offers easy speed control, long life and low operating costs.
