  • Designation key
  • The units are intended for supply, exhaust and supply and exhaust ventilation systems requiring a powerful air flow: commercial, office and other public or industrial premises as well as rooms with high humidity.
  • The fans are compatible with Ø 200, 355 and 400 mm air ducts.
  • The casing is made of polymer (for models 355 and 400, the casing is additionally 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 VENTS Boost fans are equipped with singlephase high-efficiency three-speed asynchronous motors with low power consumption.
  • The motor is equipped with thermal switches for overheating protection.
  • The ball bearings ensure a long service life (about 40 000 hours of continuous operation).
  • The motor ingress protection rating is IPX4.
  • The three-speed motor can be controlled using a built-in switch (option V) or an external switch P3-5.0 (purchased separately).
  • The fans can be mounted at any place and at any angle within the ductwork system.
  • Several fans can be installed in one system in parallel to attain higher air flow or in series to increase operating pressure in the system.
  • The fan casing is equipped with fixing brackets for floor, wall or ceiling mounting.
  • The fans can be mounted using KM-Boost brackets of the appropriate size (purchased separately, available for 355 and 400 models).
