With the continuous development of the modern industrial process, many factory owners have begun to install electric smoke ventilator on the factory floor to meet the needs of factory ventilation, lighting and smoke extraction, because they are installed on the roof, exposed to the outdoors, and have been exposed to wind and sun. It is required to have high corrosion resistance and no hidden danger of water leakage when exposed to the sun and rain. 

chemical waterproofing

At present, the smoke ventilator of the vast majority of fire-fighting electric smoke exhaust skylight manufacturers at home and abroad is mainly composed of four aluminum profiles with broken bridges. These "corner gaps" are exposed outside the workshop and connected to the workshop. If they are not treated, water leakage will inevitably occur. The common practice of electric ventilation skylight manufacturers is to use chemical substances such as silicone and tape to fill the gaps and plug the leaks for waterproofing. However, the chemical substances are easily aged and cracked due to the influence of the environment, so there is a hidden danger of water leakage.

"Nail-free, glue-free, waterproof structure"

Mcwell is the inventor of the "Nail-free and glue-free structural waterproofing" technology, which means that the electric smoke exhaust ventilator produced by Mcwell are not nailed or glued, and only rely on their own structure for waterproofing. Thereby avoiding the hidden danger of water leakage caused by the aging and cracking of materials such as silica gel and tape.

The waterproof method of the skylight for lighting, ventilation, fire, smoke and exhaust will have an important impact on the later use of the plant. If there is water leakage in the smoke exhaust and lighting skylight, the light will affect the normal production, the heavy will stop the production, and even cause immeasurable losses. Therefore, the owner and the general contractor need to be cautious when choosing a smoke-exhaust sunroof manufacturer.
