Viscous Fan 280HP 654MM DIA
The Viscous Fan 280HP 654MM DIA regulates engine cooling by adjusting fan speed based on temperature.
This fan uses a viscous clutch mechanism that automatically increases or decreases rotation depending on coolant and air temperature. Its large 654 mm diameter ensures strong airflow, supporting effective heat dissipation from the radiator and engine components. Designed for 280 HP engines, the fan provides reliable cooling under heavy loads, high temperatures, and demanding driving conditions.
By maintaining optimal engine temperature, the viscous fan improves performance, prevents overheating, and enhances fuel efficiency. It also reduces unnecessary fan power consumption by engaging only when needed, contributing to quieter operation and longer engine component life in commercial diesel vehicles.
Key Features
- Viscous temperature-controlled cooling fan
- Large 654 mm diameter for high airflow
- Supports 280 HP engine cooling demands
- Reduces overheating and improves efficiency
