Diameter, Reversible, 2,350 cfm, Black, Plastic, Kit – Perma-Cool standard electric fans are capable of moving almost twice the volume (cfm) of air as competitive models and still deliver a lower amp draw. Standard models feature high-strength, glass-filled polypropylene blades and shrouds. The straight blade design flows substantially more air than spiral blade designs and their low-profile construction is ideal for vehicles with limited space. They also offer reversible push/pull operation for mounting on either side of the radiator making them ideal for use as auxiliary cooling fans. Keep your cool with the Perma-Cool standard electric fans designed for your application.
