Hidria 500mm, 400V 3Ph Axial Fan

Made in Slovenia, Europe

The Hidria R13R-5030A-4T2-7002 (ordering code 0313-4-0006) is a high-efficiency three-phase AC axial fan featuring stamped aluminum blades and an integrated guard grid. It is primarily engineered for heavy-duty commercial refrigeration condenser units, chillers, and large industrial ventilation systems.

  • Fan Diameter: 500 mm
  • Model Number :R13R-5030A-4T2-7002 (ordering code 0313-4-0006)

Model Code Breakdown

  • R13: Product line/external rotor motor series identifier.
  • R: External rotor AC induction motor type.
  • 50: 500 mm nominal blade/impeller diameter.
  • 30: 30-degree blade pitch angle (designed for higher volumetric pressure displacement than the 25-degree version).
  • A: Sucking / Suction airflow direction (pulls air through the blades and over the motor).
  • 4T2: 4-pole, three-phase (Tri-phase) AC motor with dual-speed configuration capabilities (via Star/Delta wiring)
