A complete line of high-efficiency radial fans for use in wall-mount air conditioning units, commercial kitchens, and cleanrooms is now available from Rosenberg USA Inc. Designated the DRAD Series, these compact blowers feature forward curved impellers in diameters ranging from 5.24 to 15.75 in. They are ideal for air conditioning evaporator applications from 1.5-ton to 15-ton capacity.

MacroAir has introduced AirEffect, a climate control system for large diameter fans. Through automation, AirEffect eliminates the need to constantly monitor and adjust the fans’ speed and direction in response to temperature fluctuations. AirEffect identifies and dictates the optimal operating speed and direction for each fan based on the facility’s temperature and humidity.
