High temperature fire exhaust fan series three-phase asynchronous motor is a fully enclosed single speed motor independently developed by Suzhou Deneng Motor Co., LTD. Advanced motor design concept; Fully considering the load characteristics of the smoke exhaust fan, it has the characteristics of compact structure, high energy efficiency, low noise, low vibration, stable reliable operation, long service life so on. The motor relies on the wind generated by the operation of the fan at the load end for cooling, the structure is more compact than that of the ordinary motor, which greatly saves the installation space provides strong support for the compact structure of the fan design. According to the needs of fire smoke exhaust environment, the motor designed for high temperature resistance can meet the requirements of the motor in CA211-1999 Test Method for High temperature resistance of fire smoke exhaust fan, can run normally for 2 hours at an ambient temperature of 250 degrees Celsius, meeting the requirements of fire smoke exhaust motor.

Main Performance Main Performance

• Rated Power Range:0.75-315KW

• Rated Frequency: 50Hz
