Four points for attention in daily installation of exhaust fan?

Attention should be paid to the following matters when installing the smoke exhaust fan:

1. The foundation of the fan should be level and firm, and the foundation height should be more than 200mm. 2. The fan and the air pipe are connected by flexible material (non-combustion) , the length should not be less than 200mm, and the diameter of the pipe is the same as the size of the fan inlet and outlet. In order to ensure that the hose in the system operation process does not appear distortion, should be installed in a moderate degree of tightness. The canvas hose installed on the suction end of the fan can be installed a little tighter to prevent the fan from being sucked in during operation, reducing the cross-sectional size of the canvas hose. 3. The steel support of the smoke exhaust fan shall be fixed on the concrete foundation, and the rubber damping pad shall be added between the steel support and the foundation of the smoke exhaust fan. All fan and motor components are installed in the whole of the steel bracket, steel frame installed in the top of the foundation on the damping pad, damping pad with porous rubber plate. 4. The pipe diameter of the fan outlet can only be larger, not smaller, the air outlet to install anti-insect net, biased upward wind to increase the rain cap.
