What should be paid attention to when installing the fire exhaust fan?

2. The pipe diameter at the outlet of the fire-fighting smoke exhaust fan can only be increased, not decreased. Finally, insect-proof nets should be installed at the outlet, and a wind and rain cap should be added when the wind goes out upward.

3. The fire exhaust fan and the air pipe are connected by hose (flexible material and non-burning), the length should not be less than 200mm, and the pipe diameter is the same as the size of the inlet and outlet of the fan. In order to ensure that the hose will not be twisted and deformed during the operation of the system, the tightness of the installation should be moderate. For the canvas hose installed at the suction end of the fan, it can be installed slightly tighter to prevent the fan from being sucked during operation and reduce the cross-sectional size of the canvas hose.

4. The steel support of the fire exhaust fan must be fixed on the concrete foundation, and the rubber damping pad must be added between the steel support of the fan and the foundation. All fan and motor components are installed on the whole steel bracket, and the steel floor frame is installed on the vibration damping pad at the top of the foundation. The vibration damping pad is preferably a porous rubber plate.
