Aluminium Intake Louver with Adjustable Width

The Dayton 2FTV4 is a stationary-blade intake louver built from aluminium. It mounts on a surface with a flanged frame and provides a free area of 1.3 sq ft. The unit handles a maximum intake of 1,565 cfm and a maximum exhaust of 2,240 cfm. Water penetration begins at 766 fpm and the maximum air velocity is 3,000 fpm.

Suited for Fixed-Opening Ventilation Projects

This louver fits rough openings of 14 in height by 24 in width and suits installations that need a non-drainable aluminium blade profile. Buyers who require a drainable blade design or a motorised adjustable blade should look at other product types. The fixed 45-degree blade angle also means it will not serve applications needing variable blade positioning.

Verify Rough Opening and Mounting Surface Before

Confirm the wall opening measures 14 in high by 24 in wide to match the rough opening dimensions. Ensure the mounting surface can accept a 2 in flange width and a 4 in frame depth for surface mounting. The overall width adjusts from a minimum of 28 in to a maximum of 46 in, so check the available wall space accommodates that range.

Questions about this item

What rough-opening size must my wall already have for the 18 by 28 inch Dayton 2FTV4 louver to fit?

The unit needs a rough opening of 14 inches high by 24 inches wide; the flange adds 2 inches on each side to reach the 18 by 28 inch outside dimensions.

Can I install this adjustable louver next to an existing 28-inch-wide duct without changing the duct width?

Yes — the frame adjusts from a minimum 28-inch outside width up to 46 inches, so it can match a 28-inch duct at its narrowest setting.

How do I confirm the louver is performing within its rated limits after installation?

Measure face velocity through the 1.3 sq ft free area; intake should stay below 766 fpm to avoid water penetration and never exceed 3000 fpm maximum air velocity.
