While filters play a passive role in engine protection, they nevertheless must work together with the lubricating oil to keep engines protected and clean. Lubricating oil acts to reduce friction, wear & tear in cool engine parts, seal combustion chambers, clean engine components and inhibit corrosion. The protective action of the lubricating oil and its additives are supported and balance by the work of the lube filter.Lube Filters, particularly those designed for heavy-duty applications, have the sole purpose of keeping damaging contaminants away from sensitive engine parts. During the process some particles adhere to filter media as the oil flows through the filter. Such particles attach themselves to the media surface without plugging up the media pores. Most of these particles are trapped in the outer portion of the media, leaving the inner media surfaces open to continue catching particles that slip through. Eventually, however, media pores will fill up and the filter begins to lose its effectiveness.Filter media today ranges from the long popular and proven cellulose to synthetic media made of fiberglass, polyester, micro glass and various blends of these materials. Each type of media has specific applications for which it is best suited.

The easiest and most cost effective way to lower maintenance expense and help to ensure trouble-free system operation is through filtration. Improving system oil cleanliness levels, providing better cold start performance and meeting service interval expectations are primary objectives of a hydraulic filter. A hydraulic filter utilizes two types of depth filtration media: Cellulose Media & Synthetic Media. Cellulose Media comes in many efficiency grades, most cellulose hydraulic and transmission filters range from 15 to 40 microns. Synthetic Media is the choice in higher pressure, heavy-duty mobile and industrial hydraulic transmission applications. These man-made glass fibers are very uniform in size and shape. Synthetic media elements may cost slightly more, but offer significant performance advantages such as improved efficiency to protect sensitive controls and extended equipment life.Expensive hydraulic equipment may require synthetic media to accommodate high flow rate, while maintaining high efficiencies. Equipment owners need to choose their filters based on equipment manufacturer’s recommendations, which are typically working environments and specific equipment demands.

The deterioration of fuel is almost inevitable. Contaminants are introduced into the fuel system through mixing, transferring, and storage. These contaminants spread through the fuel system and quickly plug the fuel filter. A coating of slime will develop over the entire surface of the media. Contaminants arrive in your fuel in two forms- precipitates and particulates. Precipitates are generally heavier than fuel, and tend to settle to the bottom of tanks. Particulates are black, tar-like contaminants. There is n o known chemical treatment for the removal of these contaminants.Potentially the most damaging of all contaminants, water, destroys the lubricative properties of your fuel. With lost lubricity, the fuel can scour pumps and even blow out injector tips. Hence fuel filters protect your engine from the harmful effects of water and contaminants in fuel. They will also help increase engine performance and life.

Air is necessary for successful combustion in your engine. Clean air- air almost 100% pure is critical to engine survival and vital to its performance. Most engine manufacturers specify minimum initial efficiency of at least 98.5%. This figure may seem very high; however, it is important to remember that dirt in any amount can be harmful to your engine.The Air Filter element establishes a barrier for the separation of airborne contaminants, allowing only clean air to enter the engine. Air Filters enhance performance, delivering the clean air that powers your engine and extends its useful life by thousands of miles down the road. It is impossible to determine, just by looking, when air filters should be changed. An element that looks relatively clean may be almost totally plugged with ultra-fine particles from exhaust smoke or air pollutants. On the other hand, a filter that looks dirty may still have many hours of useful life.We do not recommend the cleaning of air filter elements. Since all contaminants cannot be removed, service intervals become progressively shorter. Further, the cleaning process might damage the filter, leading to engine damage as well.
