A new series of ECOFIT motorized fans with backward impellers are scheduled to be introduced at the AHR Expo by Rosenberg USA. The fans are designed to deliver low-noise and high efficiency in applications such as domestic air-conditioning, electronic cabinet cooling, low-power industrial heaters, and cowl ventilation.
According to the company, until now, only one other company worldwide has offered this product to these specifications. The new fans feature IP44 protection, are UL-listed, and are rated to Class F with optional thermal protection. Airflows reach a maximum of 215 CFM. The unit’s compact wheel is said to be an easy fit in free blowing designs (with screening) in circular, rectangular, and scroll-shaped housings. The plastic impellers measure 135 by 42 mm. Noise is a low 56 dBA at 60 Hz, 53 dBA at 50 Hz. Available accessories include inlet cones, inlet guards, and UL-listed capacitors.
