Diesel fuel filter with gold and silver components on a white background

More Than a Filter. A Complete Fuel Management System.

Contaminated fuel is the #1 cause of diesel engine shutdowns and it usually starts long before you notice a problem. Our systems are designed to prevent this from happening because it’s a safety
issue. No matter if you are just heading out for a day cruise, planning an offshore passage, or managing a backup power system onshore, diesel engine reliability is non-negotiable.  That’s because your diesel engine is the heart of all these applications, and many more. In particular, on boats, your engine is how you maintain control of the vessel. 

It’s a fact that 99.9% of diesel engine shutdowns are due to a lack of fuel caused by clogged filters or air leaks. Having a system onboard that allows you to perform preventative fuel testing and maintenance insures clean fuel delivery to the engine. Most vessels only allow you to add fuel to the tanks or change the filters, which opens you up to sudden engine shut down without warning.

That’s where Keenan Filters come in

All Keenan systems provide the operator advance warning when a problem starts and incorporate the tools you need to correct the issue. They also allow for system testing (like a preflight on a plane) before you leave the dock as well as the ability to perform preventative maintenance like fuel polishing, priming to ensures clean fuel reliability.
