Rosenberg's new 560-mm backward curved fans with size 6 Gen 3+ EC motors deliver all the features and benefits of our innovative Gen 3 motors plus more cooling power.  The Rosenberg GKHM 560-CIG.160.6NA Gen3+ (PN # N88-56604) comes standard with 7.2kW 3~ 460V EC motor, coupled to a super-efficient impeller.  Airflow at 460-Volt exceeds the two “magic numbers” of 6 kW fans for data center cooling and high-efficiency HVAC: 6000 cfm @ 6” of pressure and 8000 cfm @ 4” of pressure. The new fans are in stock now, available for immediate shipment. Click here to see the full Gen 3+ lineup.

Rosenberg’s new EC motors are 30% more powerful than the previous "Generation 2" motors of the same size. They offer a standard input voltage range of 200-480 VAC (50/60 Hz) and automatically adjusts to the actual input power across the entire range, allowing reduced inventory cost and easier design-in. Data on the new “Gen3” fans are included in Rosenberg's fan selection software, RoVent10.
