Detailed introduction of product materials

-Filter material: Imported grade resin bonded glass fiber filter material is used, with a multi-layer gradient composite structure. After high-temperature resin curing treatment, the pores of the filter material are uniform, the permeability is good, and it is not easy to deform or lose powder. Compared with ordinary filter paper filter material, the pollutant holding capacity is increased by more than 40%. There is no damage or medium detachment under high-pressure oil flow impact, which meets the technical specifications of PALL original filter media.

-Internal and external skeleton: The entire body is made of 304 stainless steel perforated skeleton, which has high support strength and can resist the impact of high-pressure oil circuit, effectively preventing the filter element from being flattened and deformed. It is suitable for long-term high-pressure continuous operation conditions, corrosion-resistant, not easy to rust, and has a longer service life.

-Sealing rubber ring: using NBR nitrile rubber seals (suffix H standard), suitable for conventional industrial hydraulic oil, with tight sealing, high temperature resistance, and oil corrosion resistance, to prevent oil pressure and leakage problems in the oil circuit, and to ensure that the sealing performance of the filtration system meets the standard.

-End cap structure: Thickened metal end cap with precision injection molding process, high fit, stable installation, compatible with original filter housing, 100% installation compatibility.

Main applicable scenarios and industries

Core advantages of source factory substitution

Xinxiang Lifeierte Filter Corp., Ltd as a professional manufacturer of imported filter elements, our factory has been deeply involved in the filtration industry for more than 5 years, focusing on the localization of various imported filter cartridges such as PALL, PARKER, JOINELL, etc. We have a complete production, testing, and research and development system. Compared with traders and small workshops, our advantages are very prominent:

-Original factory process replication, performance benchmarking imported: relying on a comprehensive database of imported filter element parameters, the original factory structure, filter material ratio, and production process are accurately replicated. Each filter element is produced and tested according to ISO2941 and ISO2942 international filtration standards, and its performance, accuracy, and service life are comparable to those of original imported products.

-Mass production at the source, extremely cost-effective: no middleman markup, factory independent production and sales, price is only about 1/5 of the original imported filter cartridge, significantly reducing enterprise equipment operation and maintenance, accessory procurement costs, and adapting to bulk procurement needs.

-Strict quality control and traceable quality: from filter material procurement, production and processing, folding and bonding, sealing testing, pressure difference testing to factory quality inspection, multiple processes are controlled throughout the process, and each batch of products has a sampling test report to eliminate defective and inferior products.

-Support customization and after-sales guarantee: We can customize high and low temperature resistant, corrosion-resistant, high-strength filter cartridges according to customers' special working conditions. All products support warranty and after-sales service, and can be replaced free of charge if not damaged by human factors. The after-sales response is timely.

Frequently Asked Questions and Answers

Q1: Can this domestically produced replacement filter completely replace PALL's original HC8904FKN39H?

A: It can be completely replaced. The product is a 1:1 replica of the original factory size, interface, filtration accuracy, and pressure performance. The filter material process and structural strength are benchmarked against imported standards, and can be directly installed and replaced in situ. It is compatible with all filtration equipment equipped with the original HC8904FKN39H filter element, and the operating effect is consistent with the original.

Q2: What is the approximate lifespan of the filter element and how often does it need to be replaced?

A: The service life varies slightly depending on the cleanliness of the working conditions. Under conventional clean hydraulic oil working conditions, the service life can reach 3-6 months; Under harsh dust and high impurity conditions, the service life is 1-3 months. Industry standard: When the pressure difference of the filter element reaches 0.35MPa, it is recommended to replace it in a timely manner to ensure stable operation of the equipment.

Q3: What is the maximum pressure that this filter can withstand and is it compatible with high-pressure hydraulic systems?

A: This filter element can withstand a maximum working pressure difference of 21MPa (210bar) and is suitable for various high-pressure hydraulic and lubrication systems in power plants, heavy industries, metallurgy, and other industries. Under standard operating conditions, there will be no deformation, flattening, or leakage of the filter element, and the stability under high-pressure conditions is excellent.

Q4: Apart from PALL filters, what other oil filtration related products do you have?

A: Our factory has a complete line of oil filtration products, which can meet the purification needs of industrial oil products under all working conditions.
