Why choose glass fiber oil filter element

Glass fiber is selected as the filter medium of hydraulic oil filter elements because it is often superior to other materials (such as wood pulp cotton, metal mesh, synthetic fiber) in key performance indicators and can meet the strict requirements of modern hydraulic systems for high efficiency, high strength and long life.

When should glass fiber filter elements be preferred?

Given the advantages listed above, choosing glass fiber filter elements is a wise decision in the following scenarios:

• High-pressure or critical hydraulic systems: For example, construction machinery, injection molding machines, and machine tools. These devices demand stringent oil cleanliness requirements, and the high precision and stability of glass fiber are crucial for system reliability.
• Seeking long life and low maintenance costs: While the initial purchase cost of glass fiber filter elements may be slightly higher, their longer replacement intervals significantly reduce overall maintenance costs and downtime, resulting in higher long-term economic benefits.
• High-temperature operating environments: When equipment operates at high temperatures, the excellent temperature resistance of glass fiber ensures that its filtration performance remains unchanged.
• Using synthetic hydraulic fluids: Many high-performance synthetic oils (such as phosphate esters) are highly corrosive, but the excellent chemical resistance of glass fiber provides excellent compatibility with them.

Points to Note

Of course, fiberglass filter elements are not a panacea. There are a few key considerations:

• Water sensitivity: If the hydraulic system has a significant moisture problem (emulsified oil), the fiberglass filter layer may become clogged with water, causing a sharp increase in differential pressure and shortening its lifespan. Therefore, systems with high moisture content require additional water removal and filtration equipment.
