CENTRIFUGAL ROOF FANS - HORIZONTAL OUTLET
 
 
Fan Components and Material Properties
The mounting plate and fan cap of the BRF series horizontal discharge centrifugal fans are made of electrostatic powder-coated sheet metal. The fan wheels of the BRF models are made of high-quality galvanized sheet steel resistant to corrosion.  All models have an external rotor motor with a closed structure. The device is capable of handling air at max. 40ºC.
 
Fan Structure
The fan blades are aerodynamically curved and provide regular flow. The fans are composed of backward-sloping and infrequently arranged fins.
 
Benefits
Lightweight and compact housing for easy installation. Thanks to the aerodynamic wing structure, they work quietly. Speed can be adjusted with speed control devices.
 
Speed Control
Optional control devices can be provided. Speed control can be done with linear voltage regulators in 1~phase products (see BSC accessory). Speed control with frequency inverter can be done in 3~phase products (see BSC-F accessory)
 
Usage Areas
In order to improve indoor air quality, BRF roof fans operate at low noise levels with an external rotor motor. It is used on the roofs of the places where the air is to be refreshed and the chimneys on the roofs of the bathrooms and WCs which are opened to the common shaft of the buildings.
