The definition of a 600 CFM ERV (Energy Recovery Ventilator) is a device that is used to transfer energy between two airstreams. It is designed to reduce the energy loss associated with ventilation by recovering the energy from the exhaust air and transferring it to the incoming fresh air. This helps to maintain the desired indoor air quality while minimizing energy consumption. The 600 CFM ERV is a powerful unit that is capable of handling a large volume of air, making it suitable for larger homes and commercial buildings. It works by exchanging the heat and moisture between the incoming and outgoing air streams, which helps to maintain a comfortable indoor environment. The 600 CFM ERV also helps to reduce the amount of dust, pollen, and other allergens that enter the home, making it an ideal choice for those with allergies or asthma.
