Wire Gap Filter

Linear gap filter elements are commonly used in hydraulic systems, primarily for filtering solid contaminants from media such as hydraulic oil, protecting the normal operation of hydraulic equipment.

Features
* **Filtration Principle:** Filtration is achieved through a linear gap structure formed by the precise winding of metal wires (such as copper or aluminum wire). Oil enters from the bottom of the housing, rises along the annular space to the outer surface of the filter element, and contaminants larger than the line gap width are trapped. Clean oil returns to the oil tank through the inner cavity of the filter element and exits from the top outlet.

* **Performance Advantages:** High flow capacity, some models (such as the XU-A630) can reach 630 L/min; low initial pressure loss, typically ≤0.01 MPa; high dirt holding capacity; some improved models include a flushing component, which can remove contaminants accumulated between the line gaps through backflushing.

Structure and Materials: The frame material uses copper or aluminum wire to ensure structural reliability under a working pressure of 0.35MPa. Regarding the filter element material, the use of a new type of synthetic fiber material allows for a β value (filtration ratio) of β3 ≥ 100 and a filtration efficiency exceeding 99%.

Application Scenarios: Widely used in industrial fields such as machinery manufacturing, energy equipment, petrochemicals, metallurgy, and mining, especially suitable for high-flow-rate oil return systems.
