AF Series

The VMAX AF Series exhaust/intake vent cover is a significant upgrade from traditional exterior plastic louvered grilles, offering enhanced durability and performance. Equipped with a patented backdraft damper featuring a triple-sealed and insulated interior module, it ensures ultimate home comfort by preventing cold air infiltration and reducing noise levels. Its versatile design allows for easy conversion from an exhaust outlet to an air intake, making it suitable for various applications such as central vacuum exhaust, dryer vent cover, bathroom exhaust fan vent cover, kitchen range hood vent cover, and HVAC venting systems. The AF Series is freeze-resistant, rodent-proof, and constructed with galvanized steel for robust protection against extreme weather. Available in four sizes, it combines energy efficiency
with a silent operation, making it a valuable addition to any home.

301 & 303 Series

The VMAX-301 and VMAX-303 roof vents are both CSA approved and feature innovative designs that eliminate the need for rotation to prevent water or snow infiltration, unlike traditional turbines. The VMAX-301 is designed for larger ventilation areas of 1000 to 1200 ft², while the VMAX-303 is suitable for areas ranging from 700 to 800 ft². Both models incorporate a unique storm-proof system that captures wind from all directions, creating a “chimney effect” that efficiently removes stale air and moisture from attics while drawing in fresh air through the soffits. They are compatible with various roofing membranes, including metal, and operate silently without electricity or moving parts, ensuring maintenance-free use. Built to withstand harsh weather conditions, including hail storms, and designed to remain clear of snow accumulations, these vents provide homeowners with reliable ventilation and peace of mind throughout the year.

CT Series

The VMAX CT roof exhaust trap is trusted by roofing professionals across Canada for its superior quality and efficiency. Designed to discharge kitchen range hoods, bathroom fans, and dryers, it features a built-in damper that opens to release air and closes tightly for energy savings. With an integrated deflector to prevent backdrafts and noise, it directs airflow sideways to reduce ice dam risks. Unlike traditional exhausts, it disperses air upwards, minimizing odors and rodent attraction. Maintenance-free, silent, and storm-proof with a powder-coated finish for durability.
