The shape of triangular smoke vents is triangular, beautiful in appearance, safe in structure, easy to drain in summer and not easy to accumulate snow in winter. According to the window sash opening method, The triangular smoke vents can be divided into upward opened triangular smoke ventilator and downward opened triangular smoke vent rooflight.

1. The characteristics of the downward opened triangular electric smoke vents

The smoke hatch skylight has large ventilation and exhaust capacity, and it is not easy for rain to enter into the wash when the window sash is opened.

2. Waterproof performance of downward opened smoke vent rooflight

The opening angle of C1XT smoke vent system is controlled by three gears. The first gear is ventilation and rainproof gear. In this gear, the smoke exhaust ventilator has certain ventilation performance and good rainproof performance; the second gear is normal ventilation In this position, the electric smoke vents have good ventilation performance, and also have a certain rainproof performance; the third gear is the fire smoke exhaust gear, in this position, the effective smoke exhaust port of the automatic opening vents are same with the roof openings, which has better fire-fighting and smoke exhaust performance.

Mcwell's automatic opening vent adopts the "nail-free and glue-free waterproof structure patented technology". The unique inner profile is formed in one piece, and no corner gaps are generated, which completely eliminates the risk of water leakage caused by common profiles contacting the gaps to connect indoor and outdoor. , It also avoids the hidden danger of water leakage caused by the use of silica gel to seal the leak and easy to age and crack.
