Hidria 560mm, 400V 3Ph Axial Fan

Made in Slovenia, Europe

The Hidria R13R-5625A-4T2-7002 (ordering code 0313-4-0159) is a high-capacity, dual-speed three-phase AC axial fan. Featuring a 560 mm nominal impeller diameter, this model is widely deployed in commercial refrigeration condensers, industrial chillers, dry coolers, and HVAC ventilation systems requiring flexible dual-speed configurations.
The comprehensive engineering nomenclature and technical specifications are detailed below.

  • Fan Diameter: 560 mm
  • Model Number :R13R-5625A-4T2-7002 (ordering code 0313-4-0159)

Model Code Breakdown

  • R13: Product series prefix designating the external rotor AC motor.
  • R: Mechanical configuration type (supplied with an integrated round protective guard grid).
  • 56: 560 mm nominal blade/impeller diameter.
  • 25: 25-degree blade pitch angle (engineered to minimize acoustic output while retaining high static pressure capacity).
  • A: Sucking / Suction airflow direction (draws air through the guard grid, over the blades, and across the motor housing).
  • 4T2: 4-pole, three-phase (Tri-phase) AC induction motor equipped for dual-speed functionality.

Electrical & Operational Performance

This 3-phase motor features a dual-winding design that changes performance characteristics based on Delta (Δ - High Speed) or Star (Y - Low Speed) wiring:
