Fresh Air Supply Vent

Homes today are built tighter and more energy efficient. Tight homes can cause drafting problems. When a chimney can't draw fresh air from the home, smoking problems can occur. Our fresh air kits can help solve that problem. Installs through an outside wall to let fresh air in where your heat appliance is located. Works by taking advantage of the negative air pressure of tight homes. Stainless Steel Lifetime Warranty. Made in the USA.
