Donaldson P550501 Filter Element Alternative

Donaldson P550501 Filter Element Alternative

Donaldson P550501 is another important model in Donaldson's filter product line, often used as a secondary or guard filter in conjunction with coalescer cartridges like the P550500, or as a standalone particulate filtration unit in some systems. Its main function is to capture solid particulate impurities in fuel.

Lefilter Direct Replacement Model: LF-P550501
Our LF-P550501 cartridge is designed for precise replacement of the genuine Donaldson P550501. We focus on its particulate filtration efficiency and dirt holding capacity to ensure reliable protection for downstream equipment.

Product Specification Summary:

• Corresponding OEM Part Number: Donaldson P550501

• Lefilter Model: LF-P550501

• Cartridge Type: Depth-Type Particulate Filter Cartridge

• Filter Media: Uses high dirt-holding capacity resin-impregnated cellulose filter paper or high-efficiency synthetic fiber material with precise pore size control.

• Filtration Rating (Nominal): Typically between 1 to 10 microns (depends on customer needs, please confirm when inquiring). We can provide versions with different ratings to meet various protection levels.

• Efficiency & Dirt Holding: Optimized pleat design provides a large filtration area for low initial pressure drop and high overall life dirt holding capacity.

• Structural Design:

• Includes a metal or plastic center tube.

• Sturdy end caps ensure sealing and withstand installation stress.

• May include a built-in bypass valve (per original design), which we can precisely replicate with its opening pressure.

• Operating Conditions:

• Max Working Pressure: As per design, typically suitable for common fuel system pressures.

• Temperature Range: Suitable for standard diesel fuel temperatures.

The Value of LF-P550501:

• System Integrity: Precise dimensions guarantee perfect fit with the original filter housing, preventing leaks and unfiltered fuel bypass.

• Protects Coalescer Cartridges: As a pre-filter, it effectively extends the service life of downstream coalescer cartridges like the P550500, lowering overall operating costs.

• Engine Safeguard: Efficient removal of hard particles prevents wear on injection pumps and injectors.

Common Installation Locations:

• Within a fuel filter module, positioned after the coalescer cartridge (e.g., P550500) as a polishing filter.

• On fuel supply lines as a standalone particulate filter.

• For diesel engine systems requiring high fuel cleanliness.
