Electric Puller Fan

A puller fan on the other hand sits right behind the radiator.

Electric puller fan.

It has an overall dimension of 16 inches x 16 inches x 3 3 16 inches and it a powerful puller fan of its size. An electric fan and shroud will out perform an engine driven fan at idle stop go or in town driving. Pusher style fans or puller fans. These improve the horsepower and torque delivered to the wheels by eliminating the parasitic drag of the stock belt driven fan.

Most often a pusher fan is used in cars with significant aftermarket modifications and is. Puller style fans mount behind the radiator and draw air through the core. First which is better. Independent tests have shown that even with a pusher style fan mounted only 5 8 of an inch away from the face of the radiator there is still a vast amount of air that escapes from around the skirt between the radiator and the fan blades.

A pusher fan sits in front of the radiator. Ideally the unit features 18 5 amps of current draw and will be able to pull up to 2 500 cfm. Their patented motor ensures the greatest amount of flow in the thinnest design possible. Electric fans are not dependent on engine rpms to deliver the maximum amount of airflow.

These situations are when you need the fan to perform the most. Sometimes a compact relatively quiet fan is needed. Available in puller or pusher models spal low profile electric fans provide industry leading airflow for even the most demanding radiator cores. When a vehicle is moving a pusher fan can obstruct airflow due to its positioning in front of the radiator.

Spal realizes not all vehicles require ultimate airflow. A pusher style fan can be used as an auxiliary cooling source but you should sure make the fan covers as much of the radiator core as possible. Primary electric fans pullers are designed to mount behind the radiator and replace a factory belt driven fan. Switching from an engine driven to electric fan gains horsepower fuel economy.

To answer this it seems like the consensus is in favor of the pull style fans. A pusher fan in the context of a car s cooling system is a fan mounted to the front of the radiator. Electrical fans can either push air through the radiator or pull air through it.
