ceilingcommercialplastic

USE Exhaust ventilation systems installed in high-rise buildings and premises. For buildings with mono-pipe ventilation system. For mounting in kitchens and bathrooms. Flush wall or ceiling mounting. DESIGN The fan consists of the fireproof casing BF for flush mounting and exhaust ventilation unit Valeo with a flat front panel. The casing is made of silicate plates based on calcium silicate and has high thermal insulating properties. Equipped with a fire-retarding damper to prevent fire and smoke expanding along air ducts. If temperature in the duct reaches 90°C the thermal fuse melts and closes the damper. When the fan is off the fire-retarding damper serves as a backdraft damper. The front panel is made of snow white UV-resistant plastic. Filter with filter class G4 for motor, impeller and ductwork system protection against soiling. The filter is easily accessible for service operations. Due to modern design and various colour modifications the front panel matches well with any interior. The casing is equipped with oblong slotted joints to facilitate mounting of the casing in true vertical position. If the casing is installed with some vertical deviations the special turnable grille conceals possible mounting inaccuracies. Power is supplied to the fan through a sealed electric lead-in on the casing and the ventilation unit is equipped with an airtight terminal block for connection to the wiring system. For room-to-room ventilation some ventilation unit modifications are equipped with extra spigots: Valeo-BFL – on the left; Valeo-BFR – on the right; Valeo-BFD – on the bottom. Ingress protection rating IP55.
