Description

APPLICATION
Exhaust ventilation of high-rise residential and non-residential premises with increased fire prevention requirements.	Mounting in kitchens, bathrooms, toilets, storerooms and other household areas.
DESIGN
For wall surface mounting. The front panel and the casing are made of high-quality durable ABS plastic. Equipped with maintenance-free fireretarding damper. As the temperature in the shaft reaches 90°С the thermal fuse melts and the damper shuts automatically hot air access off, and the flame and smoke ingress to the room though the ventilation shaft system is prevented.	For easy mounting the damper is mounted on a pivot rod. First mount the damper to the wall and then fix the fan casing (see mounting examples). The fire-retarding damper serves as a backdraft damper when the fan is off and prevents air moving from the ventilation shaft. Connected with the main ventilation shaft with a flexible air duct. Connecting branch pipe diameter 80 mm.
MOTOR
Energy efficient 2- or 3-speed motor on ball bearings with minimum energy demand. Automatic maintaining of constant pressure and air flow in the duct.	For precise characteristics, low noise level and safe operation each turbine is dynamically balanced while assembly.
