Fresh 80 Air Supply Vent



The Fresh 80 Air Supply Vent provides fresh air by efficiently mixing outdoor air with indoor air. This is accomplished with either mechanical exhaust ventilation or self-induced air supply. The Fresh 80 features adjustable airflow, insulation to eliminate condensation and reduce sound penetration, and dust and insect filters.

PASSIVE INLETS The Fresh 80 Air Supply Vent –  Has an adjustable passive make-up air vent. Bring in fresh air from the outdoors and provide makeup air for the mechanical ventilation system. Make-up air is an essential element in a complete central exhaust indoor air quality ventilation system, particularly in structures that are well-insulated and built tightly. The introduction of fresh air from the exterior provides the make-up air to replace air being exhausted by an exhaust fan.

Thus, indoor relative humidity levels are kept to acceptable levels and a healthy atmosphere is assured. Fresh air vents protect from excessive negative pressure in the living space and can also be a safeguard from the back drafting of toxic combustion by-products. The FRESH 80 is easily installed into an approximately 3 3/8″ diameter circular opening. This opening can be made using a standard 3 1/4″ hole saw. FRESH 80 comes complete with interior, exterior, and in-wall mounting sections
