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 reversible symmetrical 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 symmetrical profile impeller, consents to obtain the same performances in both the airflow directions with high efficiencies.
