Fire fan

Fire-fighting fan refers to an industrial fan that can run continuously for more than 60 minutes at a high temperature of 300°C for more than 20 hours per time at a temperature of 100°C.
The prior art fire and smoke exhaust fans are usually driven by the motor alone. When the power supply system fails, the power can only be provided by another mains or a backup generator set. The power distribution line of the backup power supply is relatively complicated and has certain hidden troubles.
However, with the occurrence and spread of fires, the normal power supply system and standby power distribution lines are often damaged and cannot be supplied normally, causing the motor to lose power, resulting in failure of the mechanical smoke prevention and exhaust system, resulting in casualties, equipment, and property losses. . The use of a new type of fully automatic dual-power smoke exhaust fan can effectively solve this potential safety hazard.
Under normal conditions of the power supply system, the fan is driven by the electric motor, but when the power supply system fails, the equipped engine will automatically start in a short time and continue to drive the fan to ensure the normal operation of the mechanical smoke prevention and exhaust system.
