A lubrication filter plays a critical role in a lubrication system for several essential purposes. These include:

• Providing protection for system components against damage caused by particles of critical gap size that can enter component gaps and trigger wear and potential failure.
• Controlling cleanliness to maximize the lifespan of system components.
• Enabling fluid to pass through at a certain flow rate with minimal pressure drop (Δ P).

The filter must ensure that all polluting particles are at a level that they cannot meet or exceed the critical size for the system's operation. Failure to do so can significantly increase the amount of particle generation and cause more damage. If these particles enter the working gap of components, they can damage them through wear mechanisms and lead to even more particles and more extensive damage. Therefore, the filter's role is to capture these particles to maintain the necessary cleanliness of the system.

Lubrication oil filtration is an essential part of the maintenance plan for a lubrication system. Most lubrication oil applications require high-performance filtration technology for consistent optimal fluid cleanliness and operational efficiency. High-performance, long-life filters deliver consistent output throughout their lifespan, lowering costs in industrial operations.

Petrochemicals are created through refining and chemical production processes, which require effective filtration for the separation and recovery of products and intermediate products. Filtration is also necessary for purifying liquids used in the production of magnetic tapes, optical discs, and photographic films, and for removing particles from oil field well water and natural gas.

Textile manufacturing also requires uniform filtration of polyester melt during the wire drawing process and protective filtration of air compressors, as well as the removal of oil and water from compressed gas. Reliable filtration systems are crucial for efficiency and effectiveness.

Electronics and pharmaceutical production require the pre-treatment and filtration of reverse osmosis and deionized water to ensure product purity. Filtration is also necessary for cleaning solutions and glucose. Filtration systems play a key role in ensuring the quality of these products.

Thermal and nuclear power plants depend on purified oil for various systems such as lubrication, speed control, and bypass control of gas turbines and boilers. Filtration is also necessary for feed pumps, fans, and dust removal systems. Filtration systems play an essential role in ensuring the reliability and safety of these power plants.

Mechanical processing equipment, including paper making machinery, mining machinery, and injection molding machines, require effective lubrication systems and compressed air purification. Filtration is also necessary for dust recovery and filtration of equipment such as tobacco processing and spraying equipment.

The filtration of lubricating oil and engine oil is crucial for railway internal combustion engines and generators, maintaining their longevity and performance. In the automotive industry and construction machinery, various filters are necessary for internal combustion engines, hydraulic oil, diesel, and water. Heavy-duty vehicles, ships, and construction machinery rely on efficient and reliable filtration systems for their operation and maintenance.
