Compact External Rotor Design – Motor integrated inside the impeller hub, reducing axial installation space. Ideal for space-constrained condenser and evaporator units.
High Airflow at Low Noise – Direct-drive impeller mounted on rotor delivers high airflow with minimal noise. Suitable for noise-sensitive commercial environments.
Efficient Motor Cooling – Motor positioned directly in the air stream, acting as a rotating heat sink. Extends motor life and maintains stable performance.
Built-in Thermal Protection – Thermal overload protector cuts power when winding temperature exceeds safe limits. Prevents motor burnout.
IP54 Protection – Dust and moisture resistant, suitable for outdoor and humid refrigeration environments.
Wide Size & Voltage Range – 200mm to 630mm blade diameters, 220V/380V. Covers small display cases to large commercial condensers.
Stable Bulk Supply – Standard models ship in 15–25 days. Supports rolling replenishment.
OEM & ODM Support – Custom blade diameter, voltage, speed, and mounting available. Produced per customer drawings.
Export Packaging – Seaworthy carton and pallet packaging. Suitable for long-distance ocean shipping.
