The natural ventilator is installed on the factory floor and belongs to the external equipment, which is eroded by wind and rain all the year round. Therefore, whether the material of the low-profile ventilator is anti-corrosion and anti-oxidation, and whether its structure is rain-proof is particularly important. The following mainly talks about how the MCW1 roof thin ventilator is waterproof.

1. The composition of MCW1 natural ventilator

MCW1 type roof thin ventilator is composed of supporting frame, three-layer flashing board, outer guard board, valve plate and control system (the latter two parts are optional devices). The support frame can be made of hot-dip galvanized steel plate, aluminum alloy steel plate and stainless steel plate according to the anti-corrosion requirements and the actual wind and snow load at the location of the industrial plant; Ester lighting panels (with lighting requirements) are FRP lighting panels.

2. The waterproof principle of MCW1 low-profile ventilator

The MCW1 roof thin ventilator has three layers of flashing boards, which can effectively prevent rainwater from falling into the room. The rain directly hits the first layer of the flashboard, and the resulting splashes and raindrops fall on the second layer of the flashboard. The rain directly hits the second layer of the flashboard, and the resulting splash and rain fall on the third layer of the flashboard. The bottom layer of the flashing board has its own drainage groove, and the flashing board and the drainage groove are integrally formed. The upper and middle flashing boards of this type of thin roof natural ventilator can effectively block and divert the rain or floating rain from the outside. The three-layer rain-proof and diversion structure eliminates the hidden dangers of floating rain, splashing water and rain leakage.
