BRCF-EX series vertical flush roof centrifugal fans body, mounting plate and Fan impellers made of galvanized sheet steel, models BRCF 630-800 made of electrostatic powder coated sheet steel. The suction funnel is brass plated. Asynchronous ex-proof motor is used in all models. The motor is out of airflow.

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. Direct drive, backward curved and sparse blad.

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 temperature. Due to its high temperature resistance, the hot oil vapor ab­sorbed from the hoods ensures a long distance to the vertical. The motors ex-proof feature en­sures safe exhaustion of air in hazardous environ­ments due to the fact that the aluminum and copper parts in the housing prevent electrostatic precipitation.

Optional control devices can be provided. The device must be ATEX certified in the area protection class to be used.

Ex-proof fans or ex-proof fans are one of the pre­ferred fan types for the ventilation of high-risk en­vironments. It is designed to be non-sparking. Usage areas are determined according to the de­gree of Atex directive.
