Introduction

LEFILTER, a leading Chinese manufacturer specializing in industrial fluid purification solutions, introduces the Replacement Velcon Separator Filter Model SO-640V. Engineered as a direct replacement for Velcon’s original SO-640V, this product offers identical performance, durability, and compatibility while delivering significant cost savings. Backed by ISO 9001, ISO 14001, and ISO 45001 certifications, LEFILTER ensures seamless integration into Velcon systems across industries such as pharmaceuticals, oil & gas, and petrochemicals.

Working Principle

The Replacement Velcon Separator Filter Model SO-640V operates through a three-stage process optimized for efficient water separation and particle removal:

1. Pre-Filtration:

• Multi-layer media (pleated filter paper, fiberglass) traps solid particulates and mechanical impurities.

2. Coalescence:

• Hydrophilic materials merge small water droplets into larger volumes, enabling effective separation from the fluid stream.

3. Separation:

• Gravity and hydrophobic layers separate coalesced water from the purified liquid, which is then discharged.

Key Advantages

1. High Separation Efficiency:

• Removes ≥99.9% of water droplets and solid particles ≤5μm, ensuring clean fluid for critical applications.

2. Durable Construction:

• Stainless steel housing and composite media resist corrosion and mechanical stress in harsh environments.

3. Low Maintenance:

• Long service life and automated backwash systems reduce downtime and operational costs.

4. Cost Efficiency:

• Up to 30% lower cost than Velcon’s OEM filters without compromising performance.

5. Global Compliance:

• Meets ISO 2941 (burst resistance), ISO 2942 (integrity testing), and ISO 16889 (multi-pass performance).

Product Structure

The SO-640V features a modular design with the following components:

1. Filtration Media:

• Hydrophilic composite media (polypropylene, fiberglass) for efficient coalescence.

2. Support Layer:

• Non-woven fabric provides structural integrity and uniform flow distribution.

3. Outer Wrap:

• Polypropylene helical wrap prevents pleat collapse and enhances mechanical strength.

4. End Caps:

• Glass-filled polypropylene ensures leak-proof operation.

5. O-Ring Seals:

• Viton® seals resist chemical degradation and maintain pressure integrity.

Application in Pharmaceutical Water Treatment

The Replacement Velcon Separator Filter Model SO-640V is critical for pharmaceutical applications:

1. Purified Water (PW) and Water for Injection (WFI):

• Removes endotoxins, bacteria, and particulates to meet USP, EP, and JP standards.

2. Process Water:

• Ensures high-quality water for formulation, cleaning, and equipment rinsing.

3. Wastewater Recycling:

• Separates solvents and contaminants from wastewater, enabling safe reuse and reducing environmental impact.

Other Industrial Applications

1. Oil & Gas Industry:

• Separates water from crude oil and natural gas streams, protecting downstream equipment.

2. Petrochemical Industry:

• Purifies solvents, acids, and alkalis in refining processes.

3. Aviation Fuel:

• Removes water and particulates from jet fuel, ensuring engine performance and safety.

4. Power Generation:

• Cleans lubricating oils and coolants in turbines and generators.

Conclusion

LEFILTER’s Replacement Velcon Separator Filter Model SO-640V combines advanced technology with robust construction to deliver reliable, high-quality fluid separation for pharmaceutical and industrial applications. Its three-stage filtration process, ISO compliance, and compatibility with Velcon systems make it a trusted choice for businesses seeking to optimize operational efficiency and reduce costs.
