Technical features of ring fans VD EV
- The series consists of 13 sizes with impeller diameter from 310 to 1260 mm
- Series characterized by extreme strength due to the reinforced construction of the load-bearing frame, built with greater thicknesses than those of normal square panels
- Maximum silence and high aeraulic efficiency due to the presence of inlets with a large radius of curvature made directly from the ferrule
- Construction combined with the RA type impeller which allows to optimize flow reversibility needs
- Ring conveyor, with wide-radius mouthpiece, in steel sheet protected with epoxy-polyester paint
- Motor-side safety net, made in accordance with UNI EN 294, in steel wire and protected against atmospheric agents
- High-performance impeller with airfoil blades with variable pitch angle when stationary, in technopolymer or aluminum, cast aluminum hub
- Balancing according to UNI ISO 1940 standards
- Electric motor, IP 55 protection, Cl F insulation, S1 service, construction in compliance with specific IEC/EEC standards (UNEL-MEC)
