Product specification:

7 backward-curved, aerofoil section 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 inlet.

Properties & special features:

High volume flow rates, high efficiency, low acoustic emissions due to special three-dimensional blade geometry with diagonal air discharge, reduced rotational tone. Ideally suited for low-pressure applications in confined installation spaces. Entire series meets ErP 2015 including in AC technology.

Motor concepts:

External rotor motors:

  • ECblue EC technology: with integrated controller matched to the fan
  • AC technology
