Our industrial ventilation louvers are made of galvanized steel with a powder-coated finish, offering excellent corrosion resistance and durability in harsh industrial environments. The manual crank control system allows precise adjustment of blade angle from 0 to 90 degrees, enabling users to control airflow rate and direction as needed. The 1200 CFM airflow rate per unit ensures efficient ventilation, and the temperature resistance range of -20 to 80°C makes it suitable for use in a wide variety of industrial settings. The duct-mounted design allows easy integration with existing ventilation ductwork, addressing the common pain point of inadequate ventilation control in large industrial spaces.

This louver set offers size options ranging from 12×12 inches (30.48×30.48 cm) to 48×48 inches (121.92×121.92 cm) to fit most standard industrial duct openings. Each blade has a thickness of 1.2 mm, with a net weight of 25 to 50 pounds (11.34 to 22.68 kg) per set depending on size. The package includes a mounting flange, crank handle assembly, and installation instructions. The powder-coated finish protects against rust and corrosion, even in humid or corrosive industrial environments.
This industrial ventilation louver set is ideal for commercial and industrial spaces including manufacturing factories, warehouses, power substations, ventilation equipment rooms, and commercial building exterior openings. It is used to control airflow into and out of ventilation systems, regulate indoor air quality, and protect ductwork and building openings from rain, dust, and external pests. It is particularly suitable for large industrial spaces where consistent, adjustable ventilation is required.
