Product Description
Lambro Industries - 3440NDSNT The Lambro 4-inch flush mount aluminum fresh air wall intake vent allows clean, fresh air into the home when gas appliances are present or when today’s houses are airtight.
The exhaust vent is for new and replacement installations over an existing 4-inch opening. It features an opening containing the screen with a net-free area of 11 square inches. When removing the bug screen, the net-free area of the unrestricted opening is now 20.5 square inches.
The vent’s manufacturing material is 26 gauge aluminum for durability and will not rust to maintain longevity.
All gas appliances should have a fresh air intake vent if they are indoors. These include gas heaters, fireplaces that use gas, gas water heaters, and gas dryers. If they don’t have a fresh air intake vent, they rely on the oxygen in the air, adding carbon monoxide and carbon dioxide in unhealthy ranges to the home.
Make sure to check local building codes before installation.
