Features:

• Panels, pressed in phosphated steel sheet, painted with grey epoxy powder with hammered effect to guarantee resistance over time to atmospheric agents.
• Mouthpiece, made up of a single body with panels, calibrated to optimise airflow, with an elongated aerodynamic profile to optimise performance and facilitate connection to the supply air duct.
• Protection grille (conforming to UNI ISO 13857), integral to the motor support function, made of electrowelded steel rings painted with black epoxy paint. The simple removal facilitates the maintenance and cleaning of the fan.
• 1-speed single-phase AC motor, external rotor type to minimize axial encumbrance, with shaft mounted on ball bearing supports, class F, thermo-protected
• Maximum flow rate 4063 m3/h
• Dynamically balanced impeller (UNI ISO 1940, Point 1 - Class 6.3); 4 electro-galvanized sheet steel stamped blades and polyester powder coated in black colour
• Speed controllable by Vortex regulator.
