"nail-free and glue-free waterproof structure"learn moreThe window sash and window body of the the roof smoke vent skylights do not require any silica gel, self-tapping nails, drilling or rivets; the window sash and the window body are all integrated holistically into the waterproof structure, there is no self-tapping screw, rivet, screw or bolt that destroy the integrated structure, and waterproofing completely relies on its own structure.
Integrated, modular and easy to install
The "nail-free and glue-free waterproof structure" electric lighting smoke ventilator completely eliminates water leakage hazard
High-end brand famous for reliable and long-lasting waterproof performance

Large ventilation area and low wind resistance coefficient
Mcwell is the inventor of the world's first group of "horizontal louvered" natural ventilator, the low-profile ventilator that truly realizes an effective ventilation area greater than 50%.
3.8 wind resistance coefficient of the "horizontal louvered" labyrinth industrial ventilator is far below that (16) of traditional light-weight natural ventilato.
"holistic waterproof structure"learn moreThis product is a holistic waterproof structure, i.e. it relies on its own structure for waterproofing. It does not use silica gel or adhesive tape to fill seams or to stop leakage, which avoids water leakage hazard caused by aging and cracking of silica gel and adhesive tape. Service life of the waterproof structure is the same as that of building roof panel.
Founded in 2004, Mcwell has consistently pursued 17 years of continuous research and development, and risen as a supplier of excellent ventilation solutions principally engaged in the design and production of overall ventilation, natural lighting and smoke exhaust system for workshops.
