Natural ventilator is generally used for ventilation, and is commonly used in households and industries. With the continuous promotion of industrialization, the role of roof louver vent is also increasing. So, how should we determine the suitable roof smoke vent for the plant?
1. The selection of roof louver vent should be based on the ventilation and lighting requirements of the building, and the specifications and models of the daylighting smoke vent should be determined according to the local climatic conditions, dominant wind direction, height of the building, temperature difference between inlet and outlet air, and ventilation volume.

2. The roof smoke vent is suitable for non-seismic areas and seismic areas where the seismic fortification intensity is less than or equal to 7 degrees.

3. Do the internal waterproof nodes and roof flooding nodes of the daylighting smoke vent adopt structural waterproofing technology? Some manufacturers use silica gel and tape to fill the gaps and plug leaks. The silica gel and tape are prone to ageing and cracking and there is a hidden danger of water leakage.

4. Does the factory have explosion-proof requirements? If so, the motor of the natural ventilation system should be an explosion-proof motor.

5. In areas with strong winds or snow in winter, the wind pressure resistance and snow load value of the ventilation building should be considered, and the manufacturer can be negotiated.
