Explosion-proof rolling door is on the basis of steel fire shutter door, the transmission parts to be modified, with explosion-proof electrical equipment, so as to achieve the explosion-proof function.

Explosion-proof rolling door explosion-proof motor controlled by explosion-proof electric control box, through the variable speed device to drive the scroll to make the rolling door up and down, power outages can also be used on the explosion-proof motor manual crank, can be manually operated. At the mechanical relative movement, the coupling is used instead of the chain wheel transmission, and the friction place in the track is inlaid with copper plate or nylon. It is suitable for use or storage of combustible gases, volatile chemicals and other highly inflammable goods in factories and warehouses, and other fire hazardous environments where explosions occur or may occur.
