Galvanized wall exhaust vents are external ventilation fixtures made from galvanized steel, used to vent air from a building to the outside. They are designed for appliances like kitchen and bathroom fans, featuring a hood to protect against weather, a wire mesh screen to keep out pests, and a spring-loaded damper that opens to let air out and closes when not in use to prevent backdrafts.
Key features
- Material: Galvanized steel provides durability and corrosion resistance.
- Hood: A hooded design protects the vent from rain, wind, and other weather elements.
- Damper: A spring-loaded damper is a crucial component that automatically opens for outgoing air and closes to prevent outside air, pests, and wind from entering when the fan is off.
- Screen: A wire mesh screen is included to prevent foreign objects, such as pests, from entering the ductwork. Note: Some screens can trap lint, so vents with fine screens are not suitable for dryer ventilation.
- Purpose: They are used for exhausting air from appliances like bathroom and kitchen fans. Some models can also be used for air intake or supply in certain applications.
- Installation: These vents are mounted on an exterior wall and connect to an internal exhaust duct.
