For over 25 years RenewAire has been the innovator and leader in energy efficient ventilation. Since the early 1980's, RenewAire has pioneered the use of the patented Lossnay exchange core throughout the North America, Latin America and the Caribbean. This technology reduces the concentration of harmful pollutants in indoor air by preventing cross contamination with the supply air and the exhaust air. RenewAire ERVs moderate extremes in both temperature and humidity. This not only contributes to an ideal indoor environment but also dramatically reduces the energy costs associated with providing healthy ventilation.

How It Works
In RenewAire E
RVs, stale room air is exhausted and fresh outdoor air is brought
back into the building. These two air streams are directed through a highly developed
"air-to-air" energy exchange core (the Lossnay exchange core). The following is a
explanation on the operation of this advance air exchange technology:
-
The Lossnay Core is built upon the principle of "Cross-Flow Static-Plate
Heat Exchanger". Fresh air passes through one direction, while stale
air passes through a different passage in perpendicular direction
separated by partition plates. Both air flows are completely separated,
with no gas leakage and no cross contamination.As a result, Renewaire
is perfect for controlled exhaust applications such as toilet areas, as well
as for food service and health care occupancies.
-
During Air Conditioning Season
- RenewAire ERVs provide necessary
fresh air while pre-cooling and pre-dehumidifying this air with energy
that would otherwise be lost with the exhaust air. RenewAire is typically
three times more energy efficient than products that transfer only heat.
-
During Heating Season
- Outdoor air is warmed close to room
temperature with heat that would otherwise be lost with the exhaust air.
The water vapor transfer moderates extremes in humidity levels which
helps prevent moisture damage or over-drying of the home.
Trouble-Free ERV

The scheduled maintenance for RenewAire can be performed by an janitorial staff.
No expensive service contracts are necessary because there is no wheel
dissassembly and washing, no seal or belt adjustments and no complex controls
to calibrate. The result is a trouble-free unit and the lowest maintenance cost
of any ERV.
Residential Applications
RenewAire residential products are among the highest performing products in
the Home Ventilation Institute's (HVI) Certification program for Heat and
Energy Recovery Ventilators. RenewAire provides powerful, quiet blowers in
both its ventilation fans and energy recovery ventilators so you can enjoy ample
air exchange without the objectionable noise associated with lower quality products.
-
V-Series Ventilation Fans - Economical and effective exhaust ventilation
for bathrooms, utility rooms and other spot exhaust applications. Lowest
power consumption of any fan line in the industry.
-
Breeze BR70/BR130 ERVs - Moderates extremes in outdoor humidity
year-round. Easy installation with only 2 duct connectors.
-
EV Series - The EV series is the best choice for green ventilation and save
energy year round. The EV series is a central exhaust system and uses a
small duct work system to collect air from each exhaust location. This series
can be used for general ventilation as well.
