Anping County Boli Hardware Wiremesh Products Factory, established in 1998, is a professional manufacturer specializing in high-performance filtration elements. Our PTFE Membrane Coated Fiber Filter Element with 0.45μm absolute rating delivers exceptional filtration efficiency of 99.9%, making it ideal for demanding industrial applications. With an annual export value of US$5-10 million and shipments to major ports like Tianjin and Qingdao, we bring decades of manufacturing expertise to every product.

Key Features & Technical Specifications

PTFE Membrane Coating: Provides superior chemical resistance, hydrophobic properties, and low extractables. Ideal for both aqueous and aggressive chemical filtration.
0.45μm Absolute Rating: Ensures precise removal of particles down to 0.45 microns, guaranteed by multi-layer construction and advanced manufacturing process.
99.9% Filtration Efficiency: Tested for high-efficiency particle retention, suitable for critical applications requiring consistent quality.
High Differential Pressure Capability: Withstands up to 0.5 MPa (5 bar) differential pressure without structural failure, ensuring durability in high-flow or high-pressure systems.
Fiber Core Reinforcement: The inner support structure uses high-strength fiber material to maintain shape and integrity under varying flow conditions.
Wide Operating Temperature Range: Customizable options allow operation from -20°C to 80°C (standard), with higher temperature variants available upon request.
Low Pressure Drop: Optimized pleat design ensures efficient flow with minimal energy consumption, reducing operational costs.

Applications & Benefits

Chemical Processing: Excellent resistance to acids, alkalis, and solvents ensures reliable filtration in harsh environments.
Pharmaceutical & Biotech: 0.45μm absolute rating meets sterilization-grade requirements for pre-filtration and final filtration.
Food & Beverage: Low extractables and FDA-compliant materials (upon request) make it suitable for edible liquids and beverages.
Water Treatment: High efficiency for particle removal in RO pre-filtration, wastewater, and process water.
Gas Filtration: Hydrophobic PTFE membrane prevents liquid passage while allowing gas flow, ideal for vent filters and air sterilization.
Cost Savings: Long service life due to robust construction and cleanability (backwashable in some configurations) reduces replacement frequency.

Our PTFE membrane coated fiber filter elements are manufactured with strict quality controls at every stage. The pleated design maximizes surface area while maintaining low pressure drop, ensuring consistent performance over extended periods. Each element is individually tested for integrity and efficiency before shipment.

Frequently Asked Questions (FAQ)

What does “0.45μm absolute rating” mean?
It means the filter element will retain particles larger than 0.45 microns with 99.9% efficiency. Absolute rating is more stringent than nominal rating, guaranteeing consistent performance.
Can this filter element be cleaned and reused?
In many applications, the PTFE membrane allows backwashing or chemical cleaning, depending on the contaminant type. However, for critical pharmaceutical use, single-use is recommended. Please consult our technical team for specific reuse guidelines.
What is the maximum operating temperature?
Standard version operates up to 80°C. For higher temperature requirements (e.g., up to 120°C), we can customize the materials upon request.
Is this filter suitable for aggressive chemicals like strong acids?
Yes, the PTFE membrane offers excellent chemical resistance to most acids, bases, and organic solvents. However, compatibility testing is recommended for extreme conditions.
What is the typical pressure drop across the element?
Initial pressure drop is low (typically below 0.02 MPa at nominal flow), depending on fluid viscosity and flow rate. The maximum allowable differential pressure is 0.5 MPa.
Can I get custom lengths and end cap configurations?
Absolutely. We offer customization for length, end cap types (flat, spear, 222 O-ring, 226 O-ring, etc.), and seal materials. Minimum order quantity may apply.
How does this filter compare to a standard polypropylene filter?
This PTFE membrane filter provides higher chemical resistance, hydrophobic properties, and absolute rating compared to standard melt-blown polypropylene filters, making it suitable for more demanding applications.
Do you provide certification or test reports?
We can provide factory test reports for each batch, including bubble point and efficiency tests. Specific certifications can be discussed upon request.
