Replacing your Perkins filters needs to be part of your maintenance regime. All filters have the same primary purpose – to keep unwanted debris and other material out of the working parts of the engine. Any material not caught by a filter can potentially damage the engine and, at the very least, compromise its efficiency. Within your engine, there are three important filters designed to prevent debris from entering the engine along with the media that needs to go into it. In many cases, filters are small and inexpensive but, in common with anything to do with regular maintenance, servicing them is vital. Using genuine Perkins Filters for your engine is the optimum way of keeping it running long into the future. Precision engineered to fit your engine.
