A "4D 450 Hi Cool Large Axial Fan 400mm" is a heavy-duty industrial cooling fan, part of Hicool's product line, featuring an 18-inch (450mm) blade, designed for high airflow in large spaces like factories, condensers, or clean rooms, using an axial (straight-through) flow for ventilation, often powered by AC, and noted for efficiency in demanding temperatures. The '4D' indicates a model type (likely '4-pole, Direct Drive'), '450' refers to the size in millimeters (or 18 inches), and 'Hi Cool' is the brand, moving large air volumes parallel to the fan shaft. 

A 4E-350 HiCool Large Axial Fan is a powerful industrial cooling/ventilation fan, 350mm (14-inch) in size, designed for moving large volumes of air in factories, HVAC, or agricultural settings, featuring a durable metal build, efficient external rotor motor, and suitable for both suction and blow-through applications, offering high airflow for demanding industrial cooling needs. 

The AXIAL FANS 4D600S is a 24-inch (approx. 600mm) industrial-grade axial flow fan designed for high-volume air movement in ventilation, refrigeration, and cooling applications. It typically features a 3-phase, 380V-415V motor, 1350-1380 RPM speed, and is known for its durable, powder-coated metal construction, often used in HVAC, condenser, or exhaust systems

The AXIAL FANS 4D630S (often labeled as YWF4D-630S or Hicool 4D-630) is a 25-inch (630 mm) high-performance industrial axial fan. Designed for ventilation, cooling, and heat exchange, it operates on a 3-phase 415V AC power supply, typically delivering over  of airflow at 1320-1360 RPM with low power consumption

The AXIAL FANS 6D710S (often branded as YWF6D-710S or Hicool 6D-710) is a high-capacity, 28-inch (710 mm) industrial axial fan designed for heavy-duty cooling and ventilation applications. It is characterized by its external rotor motor, metal blades, and 3-phase power supply, commonly used in refrigeration, air conditioning, and industrial equipment. 

The 6D800S is a large, 800mm diameter industrial AC axial flow fan designed for high-volume air movement in HVAC, refrigeration, and condenser units. Operating on 3-phase power (often 380V-440V), it uses an external rotor motor to deliver powerful airflow—typically exceeding 12,000 —with 6 aluminum or plastic blades.
