RING line is ideal when large air capacities are required; in applications for wall, panel or duct fixing. For instance: ventilation of industrial buildings, car parks, stock farms, cooling of electric and refrigerating equipments etc.

This line consists of 13 sizes with impeller diameter from 300 up to 1250 mm.

Ring line is characterized by the extreme sturdiness due to the strengthen construction of the casing manufactured with thickness higher than the standard Plate fans. The wide round shaped cones directly drawn on the casing guarantee maximum silent and efficiencies normally obtained only in axial fan with bell mouth. This construction together with our fully reversibile simmetrical profile impellers allows getting the 100% reversibility of the airflow. Normally the axial fans allow the reversibility of the airflow by switching two lines of phase of the electric supply and assembling 50% of the blades for intake and the other 50% for exhaust; in both cases with very low efficiencies. The use of the Ring line with the fully reversible simmetrical profile impeller, consents to obtain the same performances in both the airflow directions with high efficiencies.
