New offerings for Cummins®, Racor®, Stanadyne® Fuel Manager® FM 100 and DAVCO® Fuel Pro® systems

MINNEAPOLIS, MN – January 18, 2011 – Donaldson Company (NYSE:DCI), a leading, worldwide manufacturer of filtration systems and parts, has expanded its fuel filter offering to provide customers with even more options to protect engine components and to extend equipment life. The expanded line of replacement fuel filters includes a full complement of filters to fit:

• Cummins® engines,
• Racor® fuel systems,
• Stanadyne® Fuel Manager® FM100 fuel systems, and
• DAVCO® Fuel Pro® 380/382/482 fuel processors.

“If you haven’t used Donaldson fuel filters before, now is the time” says Rich Lewis, General Manager in charge of liquid filtration at Donaldson Company. “This expanded product line-up gives us comprehensive coverage of fuel filter applications in both on-road and off-road vehicles, provides performance that meets or exceeds application requirements, and offers features that make them easy to install and more convenient to use. It truly is a better way to filter fuel.”

Many of the fuel filters in the expanded line have Twist&Drain™ valves, which make them among the easiest to service and use in the industry. The Twist&Drain valve, a key feature on Donaldson replacement filters for Cummins and Racor systems, turns the complicated task of removing water into an easy process. This Donaldson-exclusive valve has been designed with user-friendly features:

• a wider, easy-turn “thumb and forefinger” profile,
• self-venting, allowing for easy water flow, and
• a single threaded port in the bottom of the filter housing for fast and easy water draining – without the awkwardness of multiple sensor and drain ports.

Donaldson filters for Cummins engines with Twist&Drain valves come standard with a fully integrated water-in-fuel (WIF) sensor in the drain valve for operator notification of water presence. Learn more at: http://www.donaldson.com/en/engine/support/datalibrary/067370.pdf

Donaldson filters for Racor systems (used in both on- and off-road vehicles) come with a choice of standard Twist&Drain valves or Twist&Drain valves with an integrated threaded sensor port designed to be compatible with existing OE sensors. Filters for the Racor systems also offer the option of a clear water collection bowl for visual water inspection. Learn more at: http://www.donaldson.com/en/engine/support/datalibrary/068381.pdf
