Product Detail

In all kinds of places where people are crowded or industrial equipment is displayed, eliminating fire hazard and ensuring safety are the most concerned matters for the designers and builders of such places.


Wonder Electric smoke extraction motors are designed for fire ventilation systems and can be operated at room temperature or high temperature. Under normal conditions, it works with the ventilation system to ensure indoor air flow. In case of emergency fire, the powerful performance of Wonder high temperature motor can quickly remove hot and harmful gases in the space, opening a safe passage for personnel evacuation and for fire fighter, and protecting the safety of mechanical equipment, reducing secondary damage caused by high temperature and heat.


The Wonder motors with frame size less than 132 have aluminum frame and end cover, and the motors with frame size more than 180 has cast iron frame and end cover. Wonder chooses the materials that can withstand strong mechanical pressure and chemical corrosion environment. All high temp. motors are equipped with fins and fixed feet. Foot mounting or flange mounting is optional.

Wonder Electric is able to provide protection and monitoring parts for the motor according to user's requirement. The PTC thermistor may issue a warning when the winding temperature rises to a dangerous level. The local heater can be operated when the motor is in standby to prevent condensation water from accumulating inside the motor.


Wonder smoke extraction motor can also be equipped with a frequency inverter and enhance the stator electrical characteristics to avoid damage to the motor by peak voltage.

The series are widely used in large buildings, shopping centers, factories, warehouses, enclosed parking lots and other scenes requiring fire ventilation systems.
