Heat and energy recovery ventilators supply fresh air heated by the outgoing air to the facilities.Heat and energy recovery ventilator has high efficient counter flow heat
The clearance between the fibers is very small, so only the moisture molecules of small
diameter can go through, the odor molecules of larger diameter are unable to pass through it.
By this means, the temperature and humidity can be recovered smoothly, and prevent
the pollutants infiltrating to the fresh air.
