DIRECT DRIVE ROOF FANS - HORIZONTAL OUTLET

Fan Components and Material Properties
BRCF series vertical centrifugal roof type radial fans body, mounting plate, and fan impellers made of galvanized sheet steel except BRCF 630-800 made of painted sheet steel. An asynchronous motor is used in all models. The motor is out of the airflow. The device is capable of carrying air at max. 120ºC.
Fan Structure
The fan blades are aerodynamically curved and provide regular flow. The fans are composed of backward sloping and infrequently aligned fins with the insertion technique, while the fan wheels of the models BRCF 630-800 are manufactured from the necessity of high strength.
Benefits
BRCF roof fans provide a great advantage in applications with vertical shot feature, especially in conditions where horizontal air is not absorbed. Thanks to the aerodynamic wing structure, they work quietly. Speed can be adjusted with speed control devices. Since the motor is out of airflow, it is resistant to high temperatures. Due to its high-temperature resistance, the hot oil vapor absorbed from the hoods ensures a long distance to the vertical.
Speed Control
Optional control devices can be provided. Speed control with frequency inverter can be done in 3~ phase products (see BSC-F accessory)
Usage Areas 
It is used in cases where the air is needed to evacuate horizontally in order to increase the air quality of indoor spaces. BRCF roof fans operate at low volume with asynchronous norm motors. It is used in the roofs of the places where the air is to be refreshed, the chimneys on the bathroom and WC roofs of the buildings, and the ventilation and hood system applications.
