This Flex-a-lite LoBoy Pusher fan is the most powerful puller fan of its size. With a slim shroud design, the LoBoy sits at just 3 3/16†thick at the motor, and is capable of pushing up to 2,500 cfm at 18.5 amps of current draw. Because of its slim design, the Loboy pusher is the perfect option for many applications where space is limited such as street rods, or custom builds.
