Features

BRTC Explosion-proof Centrifugal Roof Fan is an environmentally-friendly and energy-saving all-aluminum centrifugal roof exhaust ventilator jointly developed by the United States and European advanced technology research institutes. The product has a smooth and beautiful appearance design and exquisite workmanship, which meets the requirements of the building for the quality of exposed equipment. The direct-coupled motor is fully cooled within the air flow. The belt-driven motor is located at the top and is isolated from the exhaust air flow. It is more suitable for removing the polluted air with fumes, oil fog and humidity, prolonging the service life of the motor and transmission components. The use of aluminum centrifugal impeller, the balance of high grade, smooth air flow, smooth operation; with light weight, high pressure, moderate air flow, low noise, power consumption, beautiful appearance and strong advantages.

Fans generally use direct drive, light weight, maintenance-free, reliable, for roof exhaust. Products through the national authority explosion-proof testing agencies approved. According to the design requirements with the inlet smoke fire damper, fan, fire damper through the national explosion-proof electrical product quality supervision and inspection center for inspection.

Explosion-proof centrifugal roof fan produced by Nanyang Yitong explosion-proof mark Ex d Ⅱ C T4 Gb / DIP A21 TA, T4, double explosion-proof gas and dust type, not only can be used in explosive gas environment can also be used in combustible dust environment.

Optional accessories: If necessary, can be equipped with gravity check valve, anti-bird (insect) network, maintenance switch, rubber damping pad, centralized control box and other accessories.
