Engine cooling system radiator fans U45306890 move the air aiding the cooling effect on the radiator, to ensure your engine runs at the right temperature. Perkins designs the fans to provide low noise and efficient cooling by selecting the number, shape and blade material, to deliver effective airflow by movinge the right amount of air. Every fan is selected and tested with thousands of hours of testing, especially important as the higher level of emissions such as in Tier 4 higher levels of heat rejection are required, to deliver the right level of cooling.

发动机冷却系统散热器风扇U45306890移动空气，以帮助冷却散热器，以确保您的发动机在合适的温度下运行。 珀金斯设计的风扇通过选择数量，形状和叶片材料来提供低噪音和有效的冷却，并通过移动适量的空气来提供有效的气流。 每个风扇都经过数千小时的测试选择和测试，这一点尤其重要，因为更高的排放水平（例如在方法4中）需要更高的散热水平，以提供正确的冷却水平。
