Fan Components and Material Specifications of
BRCF series vertical discharge roof type radial fans. Body, mounting plate and fan wheels of models between BRCF 280-400 are made of galvanized steel sheet, fan wheels of models between BRCF 450-560 are made of aluminum sheet, fan wheels of models between BRCF 630-800 are made of electrostatic Made of powder coated sheet steel. Asynchronous motors are used in all models. The engine is out of airflow. The device has the ability to carry air at a maximum temperature of 300ºC.
Fan Structure
Fan blades are inclined backwards and have an aerodynamic structure that will ensure regular flow. While the fans consist of backward-curved and sparsely arranged blades combined with the interlocking technique, the fan wheels of the BRCF 630-800 models are manufactured due to the high strength requirement.
Advantages
BRCF roof fans provide a great advantage in applications with their vertical discharge feature, especially in conditions where it is not possible to discharge the absorbed air horizontally. They operate silently thanks to their aerodynamic wing structure. Speed can be adjusted with speed control devices. Since the motor is outside the air flow, it is resistant to high temperatures. Since it is resistant to high temperatures, it allows the hot oily steam absorbed from the hoods to be dispersed vertically over long distances.
Speed Control
can be provided with optional control devices.
In 3~ Phase products, speed control can be done with a frequency inverter. (see BSC-F accessory)
Areas of Use
It is used in cases where horizontal discharge of air is needed in order to improve the air quality of closed spaces. BRCF roof fans operate at low noise levels with an asynchronous standard motor. It is used on the roofs of places where fresh air is required, in chimneys on the roofs of bathrooms and toilets opening to the common shaft of buildings, and in kitchen ventilation and hood system applications.
