Areas of use of axial ring fans VD EV

• Ideal when large air capacities are required; in applications for wall, panel or duct fixing
• Ventilation of industrial buildings, car parks, stock farms, cooling of electric and refrigerating equipments

Technical features of axial ring fans VD EV

• This line consists of 13 sizes with impeller diameter from 310 up to 1260 mm
• Line is characterized by the extreme sturdiness due to the strengthen construction of the casing manufactured with thickness higher than the standard plate fans
• Maximum silent and efficiencies normally obtained only in axial fanwith bell mouth, guaranteed by the wide round shaped cones directly drawn on the casing
• Construction together with RA impeller allows getting the 100% reversibility of the airflow
• Ring casing, with wide round shaped nozzle, in epoxy painted steel sheet
• Motor side protection grid, manufactured according to UNI EN 294, and protected against the atmospheric agents
• Impeller with high efficiency airfoil blades, in plastic material or in diecast aluminum alloy; hub is in die-cast aluminum alloy
• Balancing according to UNI ISO 1940
• Variable pitch angle in still position
• Electric motor, protection IP 55, class F insulated, service S1, construction according to IEC/EEC (UNEL-MEC)
• Arrangement 4 (impeller directly coupled to motor shaft)
• Versions with casing with one or two round shaped nozzles
