The ultimate ventilation system, the Duo features a recovery module that recovers both heat and humidity! The most efficient energy recovery ventilator, it will continuously maintain an ideal level of air quality and proper indoor humidity.

For colder climates,  Flair offers the High Efficiency ERV Duo. Featuring twice the recovery surface, it provides maximum heat and humidity recovery at the lowest possible ventilation cost for unparalleled heating and cooling.

In summer, the reverse occurs. The Duo removes approximately 80% of the humidity from the incoming air. The unit can ventilate the basement and distribute its cooler air throughout the house. It will also reduce the cooling load on your air conditioning system, so the indoor air always remains fresh .

In winter, when air can be too dry to allow continuous ventilation using a Heat Recovery Ventilator, the Duo will recover and transfer approximately 80% of the moisture in the stale air to the fresh incoming air. This prevents problems related to overly dry air and insures unequaled comfort. Furthermore, should condensation on the windows or other condition indicate a need for dehumidification, the unit can also exhaust excess moisture quickly, thanks to an innovative device.
