Adjustable Galvanized Steel Intake Louver

The Dayton 2FTV2 is an adjustable intake louver built from galvanized steel for stationary blade ventilation. It fits rough openings of 14 inches high by 24 inches wide with a flanged frame depth of 4 inches. The outside height is fixed at 18 inches while the outside width adjusts from 28 to 46 inches for surface mounting flexibility.

Airflow Performance and Water Penetration

The louver provides a free area of 1.3 square feet with a maximum intake capacity of 1,565 cfm and maximum exhaust of 2,240 cfm. Water penetration begins at 766 fpm while the maximum air velocity rating reaches 3,000 fpm. These ratings suit ventilation systems requiring controlled airflow without active drainage.

Flanged Frame and Surface Mounting

A 2-inch flange width surrounds the 4-inch deep frame for secure surface mounting on exterior walls. The galvanized steel construction resists corrosion in outdoor installations. The stationary blade design eliminates moving parts that could wear or require maintenance. Width adjustability allows the single unit to cover multiple opening sizes without custom fabrication.

Questions about this item

How is the 28–46 in adjustable galvanized steel intake louver trap surface mounted into a 14 × 24 in rough opening?

Fit the 2 in flange against the opening, fasten through the flange holes, then slide the frame width between 28 in and 46 in until the blades align; the step often missed is re-checking the 1.3 sq ft free area after final adjustment.

What maintenance will the stationary blades and galvanized frame need over time?

Inspect blades quarterly for debris build-up that could reduce the 1,565 cfm intake rating, wipe the galvanized surfaces to preserve corrosion resistance, and verify the flange seal remains tight after seasonal vibration.

At what airflow limit does water penetration begin during sustained operation?

Water penetration starts at 766 fpm face velocity; stay below this to maintain the 1.3 sq ft free area performance and avoid moisture carry-over into the duct system.
