Comprehensive hydraulic oil filter elements and purifier machines designed for optimal industrial performance.
This industrial oil filtration solution is engineered for hydraulic oil, lubricating oil, gear oil, and transformer oil purification. It effectively removes particulate contaminants, moisture, and oxidation byproducts to extend oil service life and protect critical hydraulic and lubrication systems.
Widely used in hydraulic systems, injection molding machines, CNC machine tools, power plant turbine lubrication, steel mill hydraulic stations, and transformer oil purification.
| Position / Use | Recommended Rating (µm) | Max. Pressure | Recommended Media | HUAGONG Model Family | Selection Note |
|---|---|---|---|---|---|
| Suction line (coarse pre-filter) | 100 - 180 | ≤ 0.5 MPa (≈75 psi) | Stainless steel wire mesh / sintered bronze | WU / XU strainers | Protect pump inlet; never use fine media on suction |
| Return line | 10 - 25 | ≤ 3.5 MPa (≈510 psi) | Glass fiber (microglass) | Return-line elements | Most common; prefer βx(c) ≥ 1000 |
| Pressure line (medium) | 3 - 10 | ≤ 21 MPa (≈3050 psi) | Glass fiber / microglass | Pressure-line cartridges | Protect directional & control valves |
| Pressure / servo line | 1 - 5 | ≤ 21-42 MPa (collapse 210-300 bar) | Microglass (Betamicron-type) | HC / BN cartridges | For servo & proportional valves; β10 ≥ 1000 |
| Off-line / kidney-loop | 3 - 10 | ≤ 21 MPa | Glass fiber | LYC-A / LYC-C / LPFC purifiers | Maintain oil to target NAS cleanliness |
| Spin-on / engine & lube | 10 - 30 | Per engine spec | Composite paper / glass | Spin-on elements | Engine lube, gearbox, compressor |
| Brand interchange | 1 - 25 | Match OEM | Microglass / SS mesh | PALL / HYDAC / MAHLE elements | Send OEM No. for cross-reference |
| Coal-mine duty | 10 - 25 | ≤ 31.5 MPa | Flame-retardant glass fiber | Mining cartridges | Flame-proof environment compliant |
