PASSIVE INLETS Fresh 80 Fresh Air Ventilator – 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 backdrafting 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.
