It is applicable in the environments where there appear or may appear hazards of explosion and fire.
Technical parameters:
Blast resistance level: Sites where mixture of flammable gas in T1-t4 groups and on IIB and IIC levels, vapor and air forms explosive mixtures.
Average open/close speed: 2-9m/min
Power source: 220V/380V, 50Hz

Usegaes:
It is most suitable for the enbironments such as plants, storehouses, etc,
Where people use or keep the items with high ignition quality like flammable gas, volatile chemical drugs and so on, and where there appear or may appear explosive fire hazards. It has been qualified in the inspection of the national quality supervision, Inspection and testing centre for Anti-the bn electric products, and has been issued with the certificate of conformity for blast resistance.

Function: The blast resistance motor is controlled by the blast resistance electric control box, and it can drive the winding shaft through the speed control device, to make the curtain plate fixed on the winding shaft move up and down along the guide rails on the two sides, and push the blast resistance button to realoze the opening and closing of the door. When the shutter moves to the preset up and down extreme positions. It cuts off the power source of the motor through the limit device, to stop the shutter moving. Manual operation can be realized by using the manual handle on the blast resistance motor. In the place of mechanical relative movement, it adopts the coupleing to replace the sprocket drive, and the friction position inside the guide rail is embedded with copper plates or nylon.
