Our Plug Fans are available in 14 sizes and cover airflows up to 25 m3/s and pressure rises up to 2300 Pa. All parametrs are comparable with famous European producers. The impeller has backward curved blades. The fans are supplied with an integrated air flow sensor with two measuring points as standard. Fans are supplied in a right-hand version (viewed from the fan inlet). Our Centriflow impellers are also used within our Roof Unit range due to the high efficiency they provide.
