Axial exhaust fan BOOST SERIES

ductcommercialindustrial

Inline fans for supply and extract ventilation of various commercial and industrial premises requiring powerful air flow. The fans are compatible with Ø 355 and 400 mm air ducts. The fan casing is made of polymer and reinforced with a metal housing. Due to the conically-shaped polymer impeller with specially profiled blades the air stream circular velocity increases, which results in higher air flow and pressure as compared to characteristics of standard axial fans. The specially designed diffuser, impeller and airflow rectifier at the fan outlet provide smooth air flow distribution and enable the best combination of high air flow, increased pressure and low noise. The fan casing is equipped with an airtight terminal box for connection to power mains. The line features three-speed four-pole asynchronous motors. Fans are controlled by either a P3-5,0 three-stage or a smooth thyristor speed controllers, connected to the maximum speed terminal.
