High-CFM 11 Blade Cooling Fan OE Z530-38-65-8T11 8 Holes for 4D31 Diesel Engine Kato HD450-7 Excavator Replacement
This high-output 11-blade engine cooling fan (OE Z530-38-65-8T11) delivers maximum CFM airflow for Kato HD450-7 excavators with the Mitsubishi 4D31 diesel engine. The 11-blade configuration provides significantly increased cooling volume versus standard 8-blade designs, making it ideal for heavy-duty digging and demolition operations where engine cooling demand peaks under sustained load conditions. Each blade features an optimized pitch for superior static pressure at all engine RPM ranges.
- 11-Blade High-CFM Configuration: Engineered with 11 precisely profiled blades delivering measurably higher airflow volume than conventional 8-blade fans for optimal engine temperature regulation during continuous heavy excavation work.
- Aerodynamic Blade Geometry: Each blade features an aggressive pitch angle maximizing static pressure and air velocity through the radiator core, improving cooling efficiency at lower engine RPM common in trenching operations.
- 8-Hole Hub Pattern OE Z530-38-65-8T11: Pre-drilled 8-hole bolt pattern ensures balanced rotational stability at high RPM and secure attachment to the 4D31 water pump pulley assembly.
- Low-Noise Operation: The 11-blade balanced configuration reduces blade-pass frequency noise compared to 6-blade alternatives for quieter engine bay operation on construction sites.
- Consistent Cooling at Low RPM: Maintains adequate radiator airflow during low-speed high-torque operations typical of heavy lifting tasks where engine heat buildup is most critical.
- Direct Compatibility: Precision-engineered for Kato HD450-7 excavators with Mitsubishi 4D31 engines, guaranteed dimensional match for factory cooling system components.
