9″ OD Fan
Series 2 fans were originally developed for use on textile-type motors, but many manufacturers use these “paddle-wheel” shapes for both internal and external motor cooling. The absence of a back plate on these fans permit airflow through the motor in either direction. These fans are particularly adaptable since it is so easy to shorten the blades to reduce the overall diameter.

Overview
Cast in Aluminum, this Series 2 9″ Paddle Wheel Fan can be machined to your exact specifications by Jenkins or be provided as-is for in-house machining. The shape of the fan cover or motor housing then determines the path of higher-pressure air in these fans. Please provide exact machining specifications or call Jenkins at 800-438-3003 for machining questions.
Specs
Series 2 Padde Wheel Fans create a higher-pressure at the blade tips, typically a few pounds per square foot near the blade tips, which varies with the motor speed.
