Products Description
Hydraulic filter element in order to purify ecological resources and data reuse, and the need for purification equipment, the current filter element is mostly used in oil filtration, air filtration, water filtration and other filtration industries.
Used to remove a small amount of solid particles in the liquid or air, can protect the normal working of the equipment, when the fluid enters the hydraulic filter, the impurities will be blocked, and the clean liquid will flow out of the filter to achieve the filtration effect.
The liquid filter element enables the liquid (including oil, water, etc.) to clean the contaminated liquid to the state required for production and life, that is, to make the liquid reach a certain degree of cleanliness.
Oil filter elements are generally glass fiber, oil filter paper, metal mesh, sintered felt, brass mesh, etc., and different materials of filter elements are used in different industries.

FAQ
Q: How often should the filter element be replaced?
A: Typically every 500–2,000 operating hours, or when the differential pressure reaches 0.3–0.5 MPa (alarm value). Actual intervals should be adjusted based on oil analysis results and operating conditions.
Q: Can the filter element be cleaned and reused?
A: Glass fiber and resin-type fine filter elements cannot be cleaned or reused – cleaning damages the filtration layer and reduces accuracy. Only metal wire mesh coarse elements may be cleaned using specialized cleaning fluids and must pass integrity testing before reuse.
Q: How to select the correct filtration rating?
A: It depends on the smallest clearances of critical system components. General guideline: 3–5 μm for servo valve systems, 10 μm for proportional valve systems, and 10–20 μm for general industrial systems. Overly high rating increases pressure drop, while too low rating fails to protect components.
Q: What are the risks of continuing to operate after the differential pressure alarm triggers?
A: The bypass valve opens, allowing unfiltered oil to enter the system and accelerating pump/valve wear. The element may also collapse under excessive pressure, releasing debris into the oil circuit and causing severe equipment damage.
