Oil Filter Element Series

A: An oil filter element is a specialized filtration component designed for hydraulic systems, installed in filters and oil filters. It removes wear metal powder and mechanical impurities from hydraulic oil, keeping the oil circuit clean to extend the hydraulic system's service life. It comes in variants for suction, pressure, and return oil pipelines, each tailored to different filtration precision and system roles.s.

Diverse Materials & Structures: Constructed from stainless steel woven mesh, sintered mesh, iron woven mesh (metal layers), and filter materials like glass fiber paper, chemical fiber paper, or wood pulp filter paper. The number of layers and mesh density vary based on usage conditions.

High Precision & Reliability: Features high concentricity, strong pressure resistance, and good straightness. Stainless steel material ensures no burrs and long service life. Low-pressure series include a bypass valve that opens automatically if the element isn't replaced in time, ensuring system operation.

Wide Application & Easy Maintenance: Used in crude and fine filtration processes for lubricating oil and fuel (distillation, absorption, evaporation, etc.). Available in multiple models/specifications, with convenient installation/replacement, low initial pressure drop, and long cleaning cycles.

It is critical in hydraulic systems, categorized by installation position:

Suction Pipeline Hydraulic Oil Filter Element: Protects the hydraulic pump (installed at the tank-pump inlet), with precision typically 100–180μm.

Pressure Pipeline Hydraulic Oil Filter Element: Protects downstream components and ensures oil cleanliness, with filtration precision 5–10μm, also safeguarding the hydraulic pump.

Return Pipeline Hydraulic Oil Filter Element: Traps pollutants (e.g., wear particles) to prevent re-entry into the tank, with allowable pressure difference 0.3–0.5MPa and precision determined by oil contamination requirements.
