Fuel Filtering Simplified: Davco's Unique Approach

how does davco fuel filter work

Davco is a company that manufactures fuel filtration and water separation systems for diesel-powered engines. Their products are used in a variety of vehicles, including on-road trucks, agricultural equipment, and construction equipment. Davco's fuel filters work by first filtering out contamination, then separating water droplets from the fuel in a coalescing layer. The fuel then passes through a super-hydrophobic material that allows fuel to pass through while blocking dissolved water. This results in a higher percentage of fuel moving to the engine compared to traditional fuel filtration technologies. Davco's fuel filtration systems are known for their high efficiency, high capacity, and superior water separation abilities.

Davco's patented technology

Davco's EleMax filters are also a notable addition to their patented technology. These filters offer high efficiency and capacity filtration with three layers of incremental micron-sized StrataPore™ filter media, enhancing contamination capacity and filtration efficiency. The StrataPore™ technology ensures superior and sustained water separation over time. This is particularly important for ultra-low sulfur diesel fuel (ULSD), which requires water separation beyond what traditional media can provide.

The EleMax filter is designed for the suction side of the fuel system, ensuring effective water separation. When the engine is turned off, emulsified water collects at the bottom of the fuel processor body. Davco's filters use a three-layer approach to filtration, where contamination is filtered, and water droplets are separated from the fuel in the coalescing layer. The fuel then reaches a final layer of super-hydrophobic material, which allows fuel to pass through while blocking dissolved water. This results in a higher percentage of fuel reaching the engine compared to traditional fuel filtration technologies.

Davco's filter options

Davco also offers the Shop Pro® FXP, an all-in-one tool for priming diesel engines, cleaning fuel tanks, and transferring fuel with filtration. The company recommends using EleMax filters due to their patented vapor relief valve and half-wrap, easy-to-see filter change level, and three-layer StrataPore™ media for improved dirt-holding capacity and superior water separation. The three layers of incremental micron-sized StrataPore™ filter media increase contamination capacity and filtration efficiency. The EleMax filter is designed for the suction side of the fuel system, ensuring better water separation.

Davco's fuel processor

The first layer of the filter separates contamination from the fuel. The second layer, known as the coalescing layer, separates water droplets from the fuel. Finally, the fuel reaches a super-hydrophobic layer that allows fuel to pass through while blocking dissolved water. This process results in a higher percentage of fuel moving to the engine compared to traditional fuel filtration technologies.

The EleMax filter is designed to address the challenges posed by ultra-low sulfur diesel fuel (ULSD). When sulfur is removed from diesel fuel, it loses its lubricity, so synthetic lubricants are added. However, these lubricants increase the ability of fuel and water to combine, resulting in lower interfacial tension. Due to the low interfacial tension, water droplets can break apart and pass through to the engine with the fuel instead of dropping to the lower chamber. Davco's fuel processor with the EleMax filter prevents this issue by ensuring superior water separation.

Davco's water separation

Davco is a North American company that has been providing fuel filtration and water separation systems for diesel-powered engines since 1976. They have a range of products that cater to different applications, including on and off-highway, industrial, gen set, construction, military, and marine.

The filtration process starts with the removal of contamination, after which water droplets are separated from the fuel in the coalescing layer. The fuel then passes through a final layer of super-hydrophobic material, which allows fuel to pass through while blocking dissolved water. This results in a higher percentage of clean fuel reaching the engine compared to traditional fuel filtration technologies.

Davco's all-in-one shop floor tool

Davco's Shop Pro® FXP is an all-in-one shop floor tool that offers a range of benefits for diesel engines. Its multi-purpose functionality includes priming diesel engines, cleaning fuel tanks, and transferring fuel with filtration, making it a versatile solution for shop floor operations.

The FXP's priming capabilities ensure that diesel engines are ready for operation, while its fuel tank cleaning feature helps maintain engine performance and longevity. The tool's fuel transfer function, combined with filtration, ensures that fuel is delivered efficiently and cleanly, reducing the risk of contamination.

The FXP's filtration system is a key component, utilizing Davco's patented technology. This system separates water from fuel, addressing the issue of water contamination, which can lead to the growth of microbe colonies and cause significant engine problems. Davco's filtration process involves multiple layers, including a coalescing layer where water droplets are separated, and a final super-hydrophobic layer that blocks dissolved water while allowing fuel to pass through.

The result is a higher percentage of clean fuel reaching the engine, improving performance and reducing fuel-related issues. Davco's all-in-one tool is designed to save time and resources, providing a convenient and effective solution for shop floor diesel engine maintenance and optimization. With its advanced filtration and water separation capabilities, the Shop Pro® FXP helps extend engine life, reduce downtime, and improve overall operational efficiency.
