A person in charge of Suning at relevant matter is furious about the automatic opening vent produced by a certain factory that had been put into use for over two years. He said: "Water leaks from this batch of electric lighting smoke ventilators frequently, which affect normal usage. This problem could't be fundamentally even after repeated maintenance. The dilemma was, either remove and replace them at a great cost, or keep them in place at the great cost of constant annoyance and operation interruption".
DFSK used smoke vent skylights from another brand for its phase one factory building. After usage for half a year, it was discovered that there was frequent water leakage in the building. Through careful investigation, automatic smoke vent windows was identified as the source of the problem, but after the problem still could not be addressed even after performing numerous maintenance. Since the problem often delayed production, DFSK had no choice but to remove the troublesome ventilators and replaced them with Mcwell's smoke ventilation system with "nail-free and glue-free waterproof structure".
The traditional electric smoke ventilator is generally composed of four pieces of independent broken bridge aluminum profile and solar panels.
The gaps at the corners formed by the four pieces of aluminum profile (referred to as corner gaps) are exposed to natural elements outdoors but connected indoors. water will inevitably enter the room through the "corner gaps"
The traditional method adopted by smoke vent manufacturers is to use gel-like substances such as silica gel to seal the inside of the "corner gaps" where rainwater is unavoidable, so as prevent rainwater from entering the room through the gap.
The "nail-free and glue-free waterproof structure" patented technology ensures reliable and long-lasting waterproof performance of natural ventilator, and fundamentally resolves the hazard of leakage common in the natural ventilator industry.
The window sash and window body of the smoke ventilator with "nail-free and glue-free waterproof structure " do not require any silica gel, self-tapping nails, drilling or rivets; and are all integrated holistically into the waterproof structure.
Let the inner aluminum of the broken bridge aluminum become a whole structure, the window sash profile no longer connects the indoor and outdoor, the indoor and outdoor are separated by the integral flooding plate, and the rainwater entering the window sash is discharged outside through the integral waterproof plate, which fundamentally resolves the hazard of water leakage from smoke vent.
The traditional smoke ventilator use gel-like substances such as silica gel for waterproofing, which are prone to aging, cracking, and potential leak
Mcwell's smoke ventilator with "nail-free and glue-free" relys on its own structure for waterproofing, and has no hazard of water leakage.
The hazard of water leakage exists but this problem cannot be fundamentally resolved even after repeated maintenance. Such kinds of ventilators not only have short service life, but their poor performance affects normal production on rainy or snowy days, and often have to be removed and replaced at substantial costs and troubles.
No leakage hazard, no maintenance cost and remarkable service life on par with external structural roof panels.
The manually applied gel-like substances are often messy, and the self-tapping screws and rivets destroy the integrated structure and affect appearance.
Without nails or glue, the appearance is much more pleasing to the eye.
