Performance exhaust fan; fire exhaust fan, said during use in exhaust fan, not only to make the appropriate use and maintenance work, and to its performance fully displayed, and improve the efficiency of the fan, so as to increase its Applications range exhaust fan Usually, the majority of user acceptance. So we should make energy-efficient exhaust fan fire effect on how full performance of it, today as we detail below: For some relationship between the different flows, we adjust the way is also divided into several different approaches that adjust the way has little effect on the energy-saving effect how to use the exhaust fan, exhaust fan and even not only not saving much money, but because of the presence of adjusting means more power consumption. Variable-speed control curve closer to the ideal curve. Therefore, the variable-speed control mode is superior, especially the use of variable frequency motor speed control of energy-saving program is the best, but the need for additional frequency devices. Francis HTF temperature exhaust fan is a series of products, performance of new fans between axial and centrifugal fans between the inlet silencer equipped with a current collector, the outlet is equipped with deflector, and is designed into the second gas, help to reduce the ambient temperature of the motor. Temperature exhaust mixed flow fan with high efficiency, energy saving, low noise, compact, light weight, small size, reliable operation, easy installation, can run at 300 ℃ environment 1 hour, HTF series fire temperature exhaust fan designed for high temperature discharge smoke and design. Equipped with high-temperature fan motors, totally enclosed motor built, and a special motor cooling system to ensure safe use of the electric motors at high temperatures. By objective optimization design, the company's HTF temperature exhaust fan fire, the sentence has excellent high temperature performance, high efficiency, low noise, reasonable structure, small size and easy installation. Installed on horizontal, vertical, lifting can be. Exhaust fan introduction, exhaust fan, air conditioning provided by Chen Yu Chen Yu Wu City Air Conditioning Equipment Co., Ltd.
