PRODUCT INTRODUCTION
LEFILTER hydraulic coalescers are precision-engineered filtration systems designed to eliminate free water, emulsified fluids, and solid contaminants from hydraulic oils, lubricants, and fuel systems. Utilizing multi-stage coalescence and separation technology, our coalescers ensure optimal fluid cleanliness, protecting critical equipment from wear, corrosion, and premature failure in harsh operating conditions.
HOW IT WORKS
1. Multi-Stage Filtration Process
Stage 1: Pre-Filtration
Removes large particles (≥10µm) via high-capacity depth media to prevent coalescer overload.
Bypass protection maintains flow during cold starts or high contamination loads.
Stage 2: Coalescence
Proprietary hydrophobic media forces microscopic water droplets (0.5–5µm) to merge into larger droplets.
Optimized fiber matrix maximizes droplet collision efficiency (95%+ removal rate).
Stage 3: Separation
Coalesced water drains via gravity settling into a collection chamber.
Automatic float drain (standard) or manual drain valve (optional).
Stage 4: Polishing (Optional)
Absorbent cartridges (e.g., silica gel) reduce water content to <50ppm for ultra-clean systems.
2. Smart Monitoring & Control
Real-time sensors:
Water-in-oil detection (0–1000ppm) with 4–20mA output.
Differential pressure monitoring (ΔP > 1.5 bar alert).
IoT-ready for integration with plant SCADA systems.
