## Description

Reton 80 Fresh Air Ventilator - Adjustable Passive Make-Up Air Vent. Bring in fresh air from the outdoors and provide makeup air for 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 build 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 RETON 80 is a through-the-wall ventilator designed to provide a source of fresh air into a home or office. The unit can be installed in bedrooms, living rooms, or any other room in need of fresh air ventilation. The RETON 80 allows control over the volume

    Works ok
  

*by A***D on Reviewed in the United States on February 27, 2015*

I have only had it in for a week but it seems to work ok. It does allow fresh air in when an exhaust fan in the house is running. It took a 3.5 inch hole saw to make a large enough hole not a 3.25 saw like the instructions said.
