Product Introduction
Our high-performance hydraulic oil filtration machines are available in mobile or compact stationary designs with superior cleaning capabilities. They incorporate multi-stage filtration that captures particles as small as 0.1 microns, combined with advanced vacuum dewatering technology that removes water at less than 50 ppm. The systems also effectively separate dissolved gases.
Product Details
Working Principle
A robust hydraulic oil filtration machine combines mechanical filtration, vacuum dehydration, and gas separation. Below is the most common steps to work with:
- Pre-Filtration: Coarse 25μm mesh traps wear debris from pumps/valves.
- Depth Filtration: Cellulose/glass fiber elements remove particles >5μm.
- Vacuum Dehydration: Oil mist heated to 65°C in vacuum chamber vaporizes water (removed via condenser).
- Final Polishing: Electrostatic coalescers capture sub-micron particles.
Clean oil returns to reservoir at 0.1% residual contamination.

Features
✅ Superior Water Removal (< 50 ppm):
Vacuum dehydration under ≤ 6 mbar achieves rapid moisture separation.
Customer Benefit: Prevents cavitation, corrosion, and sludge formation; ideal for machine tools, presses, and turbines.
✅ Low Differential Pressure (< 0.15 MPa at Max Flow):
Minimizes energy consumption in transfer-pump horsepower requirements stay low.
Customer Benefit: Lowers operating costs and reduces fire hazard (no overheating).
✅ Modular Filter Cartridges with Visual / Electronic Indicators:
Quick-change filter housings; filter change-out indicator alarms when differential pressure > 0.1 MPa.
Customer Benefit: Simplifies routine maintenance; no need to guess when to replace elements.
✅ Robust Build and Corrosion-Resistant Piping:
Frame made of powder-coated steel; hoses with anti-static and abrasion-resistant linings.
Customer Benefit: Withstands harsh factory conditions and reduces downtime due to premature wear.
