At present, it is a general trend to install smoke ventilator on the roof of industrial workshops. Ridge ventilator becomes indispensable ventilation equipment in the workshops. However, in the natural ventilator industry, the quality is very different from different manufacturers which cannot guarantee waterproof performance, causing many potential safety hazards to the workshop. In the smoke ventilator market, due to limited technology a large number of smoke roof vent manufacturers cannot properly design products to meet user's requirements. Directly drilling hole on the flow plate will cause the continuous rooflight to easily leak rain.

In response to this problem, Mcwell invented the patented technology of full-structure waterproofing. The waterproofing full structure is the joint of the drainage groove of natural roof ventilation, the longitudinal overlap of the flooding plate, the longitudinal flooding plate and the horizontal flooding plate. Special accessories are used to buckle the joints of all the joints, such as the joints of the weatherproof board. The self-tapping nails are hidden. Silicone and tape are no longer used to seal the leaks. The waterproof service life of the natural ventilation system is same with the building roof outer panel. It effectively avoids the leakage.
