450 mm Diameter Inlet Axial Fan with Protective Grill – 230V, 4-Pole, 1400 RPM Motor for HVAC/R

Description

Superior Airflow Performance and Mechanical Reliability for Large Air Volumes

The Ø 450 mm axial fan is designed to ensure high energy efficiency in commercial and industrial applications where continuous heat dissipation is required. The 1400 RPM 4-pole external rotor motor assembly ensures smooth rotation and constant torque, allowing the aerodynamically profiled blades to easily overcome the back pressure generated by deep-finned heat exchangers or ventilation ducts.

The suction flow dynamics (Air Flow “S”) draw air evenly across the heat exchanger’s radiating surface and expel it through the rear grille on the motor side, optimizing convective heat transfer and preventing hot air from stagnating near the unit.

Strengths & Advantages:

• Optimized Intake Geometry (Air Flow S): The dynamically balanced blade design minimizes intake turbulence and reduces overall noise at the same airflow rate.

• 4-Pole External Rotor Motor (1400 RPM): A compact and robust medium-speed design, engineered to reduce structural vibrations and ensure efficient and consistent power delivery over time.

• Integrated Safety Support Grille: Made of sturdy electro-welded carbon steel wire and finished with an epoxy powder coating resistant to weathering and salt spray; it serves simultaneously as a safety barrier and an anchorage support.

• Long-Life Sealed Ball Bearings: A sealed bearing system that does not require periodic lubrication, designed to withstand radial and axial loads in both horizontal and vertical flow configurations.

• Designed for Continuous Duty (S1): A bimetallic thermal protection disc (thermal protector) is incorporated into the copper windings to isolate the circuit in the event of abnormal overloads or rotor lockup.
