According to Greenheck, its new Model AER direct drive sidewall propeller fan moves 30% more air compared to similar fans. This allows for a smaller fan size to be specified in order to achieve desired performance while reducing first cost. Featuring a cast aluminum propeller and an aerodynamic drive frame that helps maximize efficiency, Model AER offers expanded performance up to 29,000 cfm and external static pressure up to 2.45 in wg. Available in four sizes ranging from 20 to 36, Model AER can be specified in exhaust or supply configurations. Direct drive motor options are available up to 1 hp for Vari-Green® EC motors and up to 7.5 hp for AC motors.
