Famco sdwv4br Hooded Wall Vent 4 Inches Brown

Product Description

The FAMCO sdwv4br is a hooded wall vent designed for exhaust and ventilation applications in residential and light commercial construction. Built from metal, this 4-inch vent includes an integrated screen and a spring-loaded or gravity damper that closes when the connected system is not operating, blocking backdrafts, pests, and debris from entering the duct opening. Brown finish allows it to blend with common exterior siding and trim colors. HVAC technicians, plumbers, and general contractors install this type of fitting wherever a duct terminates through an exterior wall, including bath exhaust, dryer vent makeup, range hood discharge, and fresh-air intake points.

This wall vent is suited for 4-inch round duct systems terminating through exterior walls in residential new construction and retrofit projects. The hooded cap deflects rain and wind away from the duct opening, while the included screen adds a secondary barrier against insects and small animals. It is a common choice for bath fan exhaust, utility room ventilation, and similar low-pressure exhaust runs where a clean exterior termination is required.

Key Features

• Metal construction for durability in exterior wall applications
• Integrated screen blocks insects and debris at the duct termination
• Damper closes when system is off, preventing backdraft and heat loss
• Hooded cap sheds rain and wind away from the duct opening

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 4-inch round duct exhaust and ventilation systems in residential and light commercial applications.

Installation Notes

Installation is typically performed by HVAC technicians, plumbers, or general contractors during rough-in or retrofit work. Power down or disconnect any fan or exhaust equipment connected to the duct before cutting the wall penetration or sealing the fitting. Seal the perimeter of the vent flange to the exterior wall surface with an appropriate weatherproof caulk to prevent moisture intrusion. Verify local building code requirements for duct termination clearances and screen mesh sizing before installation.
