Air ventilators improve indoor air quality, maximizing clean and healthy air while minimizing contaminants and moisture. There are two types of in-line ventilators: Energy Recovery Ventilators (ERVs) and Heat Recovery Ventilators (HRVs). Both contain a supply and exhaust motor in one unit, bringing in fresh air from outside and pulling stale air from the living space. The unit’s recovery core ensures incoming air is not too cold during the winter or too warm in the summer.
The core in an ERV unit transfers heat and moisture to outgoing air, making ERVs perfect for the warm and dry Southeastern United States. They clean air and reduce the load on air conditioners.
HRVs are recommended in all cold climates, in addition to warm areas that are dry. They bring in an amount of air equal to that which they exhaust, transferring heat from warmer to colder air. HRVs also use defrost protection that allows year-round operation. Visit PexSupply.com to browse Fantech and Honeywell ventilators.
