EP Series Air Motors

EP Series Air Motor
Smaller motor is pictured. Larger diameter motors are flanged construction for light weight.
This family of air motors produces maximum horsepower in a given space, and their simplicity of design have earned them a reputation for reliability.

They develop maximum torque at the speeds at which Wilson cleaning heads are most efficient. The high torque developed by EP Series Air Motors is the result of their unique design that uses six light blade rotors and a double-chambered power seal cylinder.

Through an exclusive method of valving the compressed air, EP Series Air Motors are energy efficient, consuming less air than many other motors that are not as powerful. Lightweight blades reduce cylinder wear, so EP cylinders are very rarely replaced. If you are looking for EP Series replacement parts, please refer to the charts on the replacement page.

To ensure a long and reliable motor life, use WilsoLube to lubricate your EP Series Air Motor.
