Stainless Steel Pleated Filter Cartridge with Large Dirt-holding Capacity and Stable Construction for Hydraulic Systems

Stainless Steel Filter Element Pleated Filter Cartridge SUS304 SUS316L Metal Mesh Oil Filter For Hydraulic Water Filtration Tank

Hydraulic Return Oil Filter Element

Product Overview

This return oil filter element is designed for circulating filtration of hydraulic system return lines. It efficiently captures solid particles, metal wear debris and sludge mixed in returning hydraulic oil. It stabilizes oil cleanliness, protects downstream hydraulic components and minimizes system malfunctions. Widely applied in large‑flow hydraulic stations and heavy‑duty industrial machinery.

Product Features

1. Large Dirt‑holding Capacity: Extended pleated filter media provides ample filtration area, holds abundant contaminants and extends service intervals.
2. Stable Construction: Heavy‑duty metal end caps and internal support skeleton prevent filter collapse under flow impact. Good pressure‑resistant performance.
3. Outstanding Compatibility: Filter material and adhesive resist degradation from hydraulic oil, gear oil and lubricant. Adaptable to long‑time continuous operation.
4. Direct Replacement: Standard overall size and inner opening dimension. Quick swap for original filter parts without structural alteration of filter housing.
5. Rigorous Quality Inspection: Every unit is tested for burst pressure and bypass performance to avoid fiber shedding polluting the oil loop.

Main Technical Parameters

Application Scenarios

✅ Hydraulic power stations: Industrial general‑purpose hydraulic stations, large‑flow circulating oil systems
✅ Metallurgical industry: Steel mill equipment, rolling mill hydraulic return circuit
✅ Construction machinery: Excavators, loaders, cranes and heavy‑duty equipment return oil filtration
