Primarily used in dairy applications, our Tonair fans are purpose-built to inject fresh air into the barn. A niche application that is highly beneficial in specialized situations. They are the best choice of ventilation to provide milking parlors with adequate air exchange and removing humidity. They are also used in long tunnel-ventilated barns to inject fresh air and help reduce the pressure faced by the Exhaust fans.
