Mcwell full-structure waterproof natural ventilator has the following advantages:

1. Abandon the traditional use of silica gel and tape to fill gaps and plug leaks

Traditional natural ventilator generally use silica gel and tape to fill gaps and plug leaks at some waterproof nodes to prevent rainwater from leaking into the room. Silicone joints will inevitably expand and contract with temperature changes. The temperature difference in different seasons will continue to cause the shrinkage and expansion of the steel plate between the gaps. Silicone is a chemical material, and it is also prone to aging and cracking. The problems of aging and cracking will occur in about half a year. Once the tape and silica gel are aging, it will cause hidden dangers of water leakage in the ventilator. Rainwater leakage will directly cause the normal production to be unable to maintain, and in severe cases, equipment and products will be damaged.

 2. Mcwell adopts full-structure waterproof patented technology

 The waterproof performance of natural vent used in roof systems is a very important performance index. Mcwell natural smoke ventilation adopt full-structure waterproof technology, which has obtained national patent. The full-structure waterproof technology adopts special fasteners for fastening treatment at the board nodes. The special components and fasteners are mainly made of metal materials and molded by molds. Silicone and tape are no longer used for sealing and leaking, which can guarantee the maximum ventilators.
