Vortice 42207 - Axial fan A-E 252 M

Vortice 42207 - Helical fan A-E 252 M

DETails
- Nominal diameter 250 mm
- Panels, moulded from phosphate-coated sheet steel, epoxy powder-coated in grey with hammered effect to guarantee resistance over time from atmospheric agents.
- Nozzle, forming a single body with the panels, calibrated to optimise air flow, with an elongated aerodynamic profile to optimise performance and facilitate connection to the supply duct.
- Protective grille (compliant with UNI ISO 13857 standard), integral with the motor support function, made of electro-welded steel rings and painted with black epoxy paint. Simple removal facilitates maintenance and cleaning of the fan.
- Single-phase AC 1-speed motor, external rotor type to minimise axial dimensions, with shaft mounted on supports with ball bearings, class F, thermo-protected.
- Maximum flow rate 1365 m3/h
- Dynamically balanced impeller (UNI ISO 1940, Point 1 - Class 6.3); 5 blades moulded in electro-galvanised sheet steel and painted in black polyester powder.
- Speed controllable by means of Vortex regulator
