This pack of 10 high-quality cooling fans is designed for all types of water pumps, ensuring optimal engine temperature control and prolonged pump life. Made from durable mild steel, these round fans feature precision-balanced blades that efficiently dissipate heat by increasing airflow over the pump’s radiator or engine components. Their corrosion-resistant finish and robust construction make them suitable for demanding agricultural, industrial, and domestic pumping environments. With an outer diameter of 132 mm and inner diameter of 26 mm, these fans fit most standard water pump models. Easy to install and maintain, they help prevent overheating, reduce wear and tear, and improve overall pump efficiency, making them an essential component for reliable water pump operation. A cooling fan  is a fan that helps dissipate heat from the coolant (often water-based) that has circulated through the engine. It does this by blowing air over the radiator, where heat is transferred from the coolant to the air. This process helps maintain the engine's operating temperature within a safe range.
