Lukjan EX3035D Dryer Vent Wall Box 3.5 in Downward Exhaust

Product Description

The LUKJAN EX3035D is a dryer vent wall box designed for recessed installation in residential walls. It provides a dedicated exhaust pathway that allows the dryer to sit flush against the wall, eliminating the need for a large gap behind the unit. The box features a downward exhaust outlet and a depth of 3.5 inches, making it compatible with both 2x4 and 2x6 framed wall cavities. HVAC installers and finish carpenters typically install this component during new construction or dryer alcove remodels.

The EX3035D is used in residential laundry installations where wall space is limited and a recessed dryer connection is preferred. The bottom vent orientation directs exhaust downward, which suits layouts where the dryer exhaust duct runs below the unit or through a floor cavity. It fits standard 2x4 and 2x6 stud-bay construction, giving installers flexibility across common framing configurations.

Key Features

• 3.5-inch depth fits both 2x4 and 2x6 wall framing
• Downward exhaust outlet routes ducting below the dryer
• Bottom vent design supports below-floor duct routing
• Recessed box allows dryer to sit closer to the wall
• Designed for residential dryer ventilation applications

Compatibility

Designed as an OEM-style replacement and new-construction fitting for residential dryer vent installations in standard 2x4 or 2x6 stud-framed walls.

Installation Notes

Installation is typically performed by an HVAC technician or experienced installer during rough-in or dryer alcove finish work. Disconnect power to the dryer and ensure the dryer exhaust duct is de-pressurized before making connections. Verify that the total duct run complies with local mechanical codes and the dryer manufacturer's maximum duct length requirements. Use approved rigid or semi-rigid metal dryer duct to connect to the box outlet.
