7" Fan Cover for 30 Rows Oil Cooler. Installing the fan together with the fan cover provides an airflow over the entire heat exchanger, which provides a better cooling capacity than if the fan is mounted directly against the oil cooler. The cover is made of 2 mm thick aluminum, cut and bent on CNC machines and powder coated in a black structure. The kit also includes screws intended for mounting the fan. The fan cover is adapted: For fans with a diameter of 200 mm (215 mm between mounting holes) Oil cooler with dimensions ~260x235x50mm (width / height / depth)
