Throat explosion-proof fan
? The throat explosion-proof fan must ensure that the impeller and shaft will not produce sparks even if there is displacement or friction during operation. At the same time, it must ensure that the explosion-proof certification requirements of the motor meet national standards. Even if there is a short circuit, current overload or line breakdown inside the motor, sparks will not be generated due to high temperature. This is the main principle of the throat explosion-proof fan.
? The throat explosion-proof fan has been tested and complies with GB3836.1/2-2010 "General Requirements for Equipment in Explosive Environments and Flameproof Enclosures" Protection Equipment. The fan equipment can run continuously for 24 hours without trouble, with a long service life and safe use.
