The smoke vent skylights Project of Chengdu Tianfu International Airport is located in Jianyang City, Sichuan Province. It is the largest civil transportation hub airport project planned and constructed during the 13th Five-Year Plan period of the country. It is a 4F international airport, an international aviation hub, and it is the highest airport in the Silk Road Economic Belt.  The products that Mcwell supplied is a combination of triangular electric smoke ventilator and daylighting hoods. The smoke vent rooflight can also be used as fire vents. It has multiple functions of smoke, lighting and ventilation. The top is triangular, which is good for drainage in summer and not easy to accumulate snow in winter. The broken bridge aluminum profile has the function of heat preservation and heat insulation to prevent the backflow of condensed water.

Mcwell's smoke vents adopt the patented technology of "nail-free and glue-free structure waterproof". It is integrated structure. The skylight window sash profile adopts a seamless internal drainage structure, and the interior of the profile is integrated through a seamless internal drainage structure. Rainwater is discharged outside; the roof smoke vent is completely waterproof by its own structure. There are no self-tapping screws, rivets, and bolts to destroy the integrated structure, which fundamentally eliminates the hidden danger of leakage.
