High Airflow Plastic Circular Cabinet Outlet for Flat Air Vent Cap

It is integrally stamped from high-quality 304 stainless steel with polished finish. 304 stainless steel features excellent rust-proof, anti-corrosion and UV-resistant performance. It can withstand long-term wind and rain exposure on exterior walls, and will not rust or deform easily, perfectly fit outdoor wall mounting.

It has wide application. It matches kitchen range hood exhaust pipes, bathroom exhaust fan ducts, whole-house fresh air system outlets, as well as ventilation pipes of storage rooms, machine rooms and small equipment. Multiple sizes can meet different pipe diameter demands of household and engineering projects.

No. The product adopts integrated slanted louver structure as the first waterproof barrier. Raindrops will slide down along the inclined shutters instead of pouring backward into the pipeline. Cooperated with the flat wall-mounted design, it greatly reduces the chance of rain infiltration even during continuous heavy rain.

It comes with built-in dense fine metal mesh as secondary protection. The tiny mesh holes block mosquitoes, wasps, sparrows, mice, fallen leaves and sundries from entering and clogging the duct. It keeps smooth air exhaust while avoiding frequent pipeline cleaning.

Installation is simple and DIY-friendly. Just drill a round wall hole matching the vent size, insert the vent body into the through-wall duct, then fill the edge gap with weatherproof glass glue for sealing. No special brackets or complex tools are needed; one person can complete installation quickly without professional workers.
