Vertical exhaust centrifugal roof fans for air flow rates between 1100 m3/h and 18000 m3/h. The structure comprises a base of square geometry incorporating the inlet port, a cylindrical safety grille, motor complete with terminal box, impeller, protective cap, and baffles positioned to divert the extracted air upwards.DescriptionBases made of pickled and phosphate steel sheet; grey epoxy powder-coated with hammered finish.Motor cover made of pickled and phosphate steel sheet, polyester powder- coated and furnace-baked,Guaranteeing higher long-term resistance to aggressive agents over time, in grey color with hammered finish.Lateral bulkheads for vertical discharge of the air handled made of galvanized steel sheet, grey polyester powder-coated and furnace-baked, guaranteeing higher long-term resistance to aggressive agents and with hammered finish.Ventilation ports, fashioned in one piece with the body, characterized by aerodynamic profiles, calibrated to optimize the extracted airflow.Safety and anti-bird protective grilles designed in accordance with the UNI ISO 13857 standard, made of electrically welded steel rings with epoxy black paint finish.Galvanized steel sheet cover plates, designed to divert the flow of air handled, preventing it from striking the drive unit directly and thus protecting it from excessive heat loads. Class F or H thermally protected single or three-phase asynchronous motors, depending on the model, with shafts turning on ball bearings with double sealing screen, characterized by high (IP 55) degree of protection against dust and water and with cooling fans for more effective heat dissipation.Starting capacitors of the single-phase models comply with the EN 60252-1 standard and are third-party certified.Centrifugal impellers with electrically galvanized aluminum or steel sheet, depending on the model, self-cleaning, backward-curved blades, dynamically balanced (UNI ISO 1940, Class 6.3), fitted on grooved hubs in die-cast aluminum.Wiring boxes complete with molded cable glands in thermoplastic resin.Steel eyebolts for lifting and transport, protected from corrosion by galvanic treatment.Steel cables for secure anchoring of the product to the destination surfaces supplied as standard.
