Rooftop fresh air fan

● Rooftop fresh air units are suitable for water-scarce areas. They do not require water for cooling. They are installed on the roof, are easy to install, and do not occupy indoor space. With sufficient outdoor static pressure, rooftop fresh air units are easy to ventilate with air ducts, greatly reducing indoor noise.

● The rooftop fresh air unit adopts a cold bridge-free design, which eliminates cold leakage and condensation caused by the large temperature difference between the inside and outside of the unit.

● The rooftop fresh air unit’s color operation interface is simple and convenient. It can also query various operating parameters and set various parameters, perfectly combining flexibility and practicality.
