Difference in types of electric fans – puller vs pusher type

Today we had a call from a customer who asked what the difference was between a puller type and a pusher type electric fan was. Even though most of you will probably only be using your factory radiator fans, heres an explanation of the difference in type of fan – puller versus pusher type of aftermarket fans.

What is a “puller” fan?
A puller fan is a fan that is installed behind, or in back of the radiator, and wired so that when it is running, the air is “pulled” through the radiator core.

What is a “pusher” fan?
A pusher fan is a fan that is installed ahead, or in front of the radiator, and wired so that when it is running, the air is “pushed” through the radiator core.
