Fire exhaust fan, said during use, not only to make the appropriate use and maintenance work, and to the performance of fully displayed, efficient use of the fan, so as to increase its range of applications, the majority of user acceptance . So we should make energy-efficient exhaust fan fire effect on how the full performance of it, today, as we detail below: For some relationships exist between the different flows, we adjust the way it is divided into several different approaches that regulate the way little effect on energy savings, even not only energy efficiency, but because of the presence of the device to adjust the power consumption more. Speed ??adjustment curve closer to the ideal curve. Therefore, the speed adjustment method is superior, especially the use of variable frequency motor speed control of energy-saving solutions for optimum exhaust fan control box, but the need for additional frequency devices. Francis is a high-temperature exhaust fan kitchen exhaust fan HTF series of power, performance between the new fan axial and centrifugal fans between inlet silencer fitted collector, the outlet is equipped with baffles, and secondary air intake is designed to help to reduce the ambient temperature of the motor. Francis temperature exhaust fan with high efficiency, energy saving, low noise, compact, light weight, small size, reliable operation, easy installation, can run at 300 ℃ environment one hour, both for ventilation can play Fire The role of high-temperature exhaust. Temperature exhaust Francis fan Uses: used in senior civil and underground warehouses, ovens, tunnel and mining enterprises and other sectors of ventilation and fire smoke. cf type kitchen exhaust duct fan, exhaust fan, air conditioning wholesale Chenyu provided by Wu Cheng Chen Yu Air Conditioning Equipment Co..
