Electric fire smoke exhaust ventilator is more and more widely used in the market. Different factories have different emphasis on the function of smoke vent skylights. Therefore, smoke vents manufacturers have designed and produced various types of electric roof vents according to local conditions. . However, no matter which roof electric sunroof is, it needs to meet the most basic performance requirements. Among them, the rainproof performance is the most basic performance that the roof smoke exhaust skylight should meet.

1. The importance of the waterproof performance of the electric smoke exhaust ventilator

Electric smoke exhaust ventilator is installed on the roof are called roof electric skylights. At the roof where the smoke exhaust skylight is installed, it is necessary to leave a suitable opening size in advance, and then make the base, and the electric smoke vent skylights need to be installed on the corresponding foundation. Therefore, at the junction of the base and the roof, the junction between the base and the smoke exhaust ventilation skylight, and the structure of the factory's electric skylight are exposed to the outdoors, and are corroded by strong winds and rains all the year round. If the waterproofing of these interfaces is not done well, it will directly cause rain and water seepage in the workshop, thereby destroying and corroding the building, and also leaking into the factory, causing mold and deterioration of the products in the workshop, which will seriously affect normal production. , It will also bring different degrees of loss to the enterprise.

2. Waterproof technology with no nails and no glue structure

The nail-free and glue-free structure waterproof technology of the electric smoke vents adopt the integral closed-loop internal flooding. The inner section of the broken bridge aluminum profile is an integrated structure. The rainwater inside the window sash is isolated by the integral flashing board and discharged outside. The hidden danger of water leakage caused by the "corner gap" of traditional roof lighting and smoke exhaust skylights is eliminated.
