backward curved, EC, high-volume, with external rotor, low-pressure, high-performance, AC, compact, horizontal, vertical, composite, industrial
18,000 m³/h (635,664 ft³/h)
Free running Vpro impeller with 6 backward-curved, fluted blades in frame sizes 190 to 630 mm. Impeller made of high-performance composite material. Version with inlet nozzles. Volume flow rate up to around 18,000 m³/h free blowing, max. static pressure increase up to 1,300 Pa possible.
GR module for compact installation in customer applications/devices for horizontal and vertical air feed.
Properties & special features:
High volume flow rates, high efficiency, low acoustic power levels due to special three-dimensional blade geometry, reduced rotational tone. Ideally suited for low-pressure applications.
External rotor motors:
ECblue EC technology with integrated controller matched to the fan
