A family of compact radial fans with free-running impellers and variable speeds is available. The units combine electronically commutated external rotor motors with newly developed integrated power electronics. The fans’ long-life, low-temperature brushless dc motors are controlled by maintenance-free electronic circuitry. GKHR fans are mounted and balanced motorized impellers that can be provided with or without an inlet cone. GKHM fans are complete fan modules. According to the manufacturer, with reduced mechanical content, the fan motors run cooler and quieter, require little or no maintenance, and can be speed-controlled using an external potentiometer or 0-10-V PWM signal.

Rosenberg USA, 1010 Forsyth Ave., Indian Trail, NC 28079; 704-289-5423; 704-283-7170 (fax); sales@rosenbergusa.com
