RTC RTC aluminum aluminum roof fan roof fan is the introduction of foreign advanced technology combined with scientific research institutions jointly developed an environmentally friendly, energy-efficient all-aluminum roof fan, the product shape design and smooth appearance, superb technology, in line with high-grade construction equipment for exposed texture requirements, more suitable to exclude with smoke, mist, humidity and other air pollution, extend the life of the motor and drive components. With the plate-shaped aluminum centrifugal impeller, balance high level, air smooth, stable operation; a light weight, high pressure, moderate amount of wind, low noise, low power consumption, beautiful appearance and firm, etc., are widely used in machinery, chemical, rubber, pharmaceutical, textile and other industries workshop tall plant and senior civil roof exhaust ventilation. JRTC (RTC) aluminum roof fans generally use direct drive, light weight, maintenance-free, reliable, used for roof ventilation. It can be prepared JRSC (RSC) for roofs air blower. Depending on the use of the environment and transport medium, equipped with explosion-proof motors made for transporting flammable and explosive gas, explosion-proof products through national authoritative testing laboratories accredited. Equipped with high-temperature motors made of fire type, able to run more than 45min at 280 ℃ under the high temperature conditions, according to design requirements smoke damper disposed entrance, fans, dampers through the National Fire product testing center type test. Optional accessories: can be arranged as desired gravity-return valve, anti-bird (insect) network, maintenance switch, rubber damping pad, centralized control boxes and other accessories.
