Free running ZAvblue impeller with 7 backwards-curved, fluted blades in frame sizes 175 to 630 mm. Impeller made of high-performance composite material. Version with inlet nozzle made of plastic. Volume flow rate up to around 19,000 m³/h free blowing, max. static pressure increase up to 800 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 with diagonal outflow, reduced rotational tone. Ideally suited for low-pressure applications in confined installation ratios. Entire series meets ErP 2015 including in AC technology.
External rotor motors:
- ECblue EC technology: with integrated controller matched to the fan
- AC technology
