The Pall filter element is a water filter made of sintered filter material and plastic, with a standard filtration accuracy. It serves a broad range of industries, such as petroleum, chemical, metallurgical, aviation, electronics, power, pharmaceuticals, environmental protection, atomic energy, nuclear industry, natural gas, refractory materials, and fire-fighting equipment. The primary function of Pall filters is to remove solid particles and gel-like substances from the working medium in hydraulic systems, effectively controlling the pollution level of the working medium and ensuring the normal operation of the system. It is widely used in hydraulic and lubrication systems.

The material of the Pall filter element is of high quality, such as glass fiber material, oil filter paper, stainless steel, and sintered felt. The filtering accuracy ranges from 1μm to 25μm. It has structural strength and filter rupture resistance and meets the standards such as ISO 2941, ISO 2943, ISO 4572, and ISO 3968. It has a wide range of applications, including being installed at the pump's suction port, pump outlet oil circuit, system return oil circuit, system branch oil circuit, and as a standalone filtration system.

The performance indicators of Pall filters include medium type, material, filtration accuracy, working pressure, working medium, and working temperature. The filtration accuracy ranges from 1μm to 100μm, working pressure between 21bar and 210bar, and the proper working temperature is between -30℃ and +110℃. To ensure the system's maximum protection, Pall filters usually use fluorine rubber rings and nitrile rubber as sealing materials, assisting in optimizing filtration efficiency and service life while maintaining low pressure differentials and high strength.

Series number: The series number of a PALL filter element, such as HC8304, is a combination of numbers or letters that identify the basic series and specifications of the filter element. If two filter elements have the same serial number, it means that their inner and outer diameters are the same.

Filtration accuracy: The filtration accuracy of a PALL filter is represented by the letter N. For example, the HC2207FKP6H filter element has a filtration accuracy of 6um. Different letters are used to represent the filtration accuracy of PALL filters, such as Z for 1μm, N for 6μm, S for 12μm, T for 25μm, and R for 40μm.

Filter height: The filter height is represented by numbers. For instance, a PALL filter with a filter height of 39 inches is indicated as 39. This number is converted to 891mm in millimeters and represents the length of the filter element.

Seal material: The seal material used on PALL filters is represented by letters. For instance, the letter H indicates that the seal is made of nitrile rubber. Other seal materials for PALL filters are represented by different letters, such as J for ethylene or propylene, P for chloroprene rubber, and Z for fluororubber.

These components help provide a clear understanding of the specific specifications and application scope of PALL filters. For instance, the HC2207FKP6H filter element uses high-quality glass fiber filter material and metal mesh, with a filtration accuracy of 6um. This filter element is suitable for specific industrial applications that require clean fluids and safe system operation.
