Working Principle
The SO-633VA operates on a three-stage separation process to ensure thorough fluid purification:
Pre-Filtration: A coarse outer layer captures large solid particles.
Coalescence: Hydrophilic glass fiber media causes small water droplets to merge into larger ones.
Gravity Separation: The heavier water droplets settle into a collection chamber, while the purified fluid exits through the center tube.
This mechanism efficiently removes both free and emulsified water, as well as solid contaminants, protecting downstream equipment from corrosion and wear.
Performance and Advantages
The SO-633VA stands out due to its exceptional performance and design features:
High Efficiency: Removes ≥99.5% of particles ≥5 µm and ≥98% of emulsified water.
Long Service Life: Pleated media design with 5.8 m² surface area reduces pressure drop and increases dirt-holding capacity.
Chemical Resistance: Withstands hydrocarbons, solvents, and a pH range of 2–12.
Compliance: Meets ISO 2941/2942/2943 standards for structural integrity and material compatibility.
Cost-Effective: Offers a 30% longer service life compared to standard filters, reducing maintenance costs.
Product Structure
The SO-633VA features a robust, multi-layered construction designed for durability and optimal performance:
Composite Media: Glass fiber layers for coalescence and polypropylene backing for strength.
Knitted Sleeve: Protects the media from mechanical stress and ensures even flow distribution.
Reinforced End Caps: Prevent deformation under high pressure.
O-Ring Seals: Available in Buna-N or Viton® for compatibility with different fluids.
Application in Wind Power Plants
In wind power plants, the SO-633VA plays a crucial role in maintaining the reliability of various systems:
Hydraulic Systems: Removes water and particulates from hydraulic oil, preventing valve failures and ensuring smooth operation.
Gearboxes: Keeps lubricating oil clean, reducing friction and extending the life of gears.
Cooling Systems: Prevents scaling and corrosion in closed-loop cooling systems, maintaining efficient heat transfer.
Fuel Systems: Ensures clean diesel for backup generators, minimizing the risk of downtime.
Other Industrial Applications
The versatility of the SO-633VA makes it suitable for a wide range of industries:
Oil & Gas: Separates water from crude oil in pipelines and refineries.
Aviation: Purifies jet fuel to meet ASTM D1655 standards.
Marine: Protects engine fuel systems from water in saltwater environments.
Chemical Processing: Filters solvents and corrosive fluids in reactor systems.
Food & Beverage: Removes moisture from edible oils and process fluids.
Conclusion
The Replacement Velcon Separator Filter Model SO-633VA from LEFILTER combines cutting-edge technology, durability, and cost-effectiveness. Whether used in wind turbines, refineries, or aviation fuel systems, it ensures optimal fluid quality, reduces operational risks, and extends equipment lifespan.
