As a leading manufacturer with over 25 years of experience in filtration solutions, Anping County Boli Hardware Wiremesh Products Factory proudly presents our Industrial PTFE Membrane Coated Fiber Filter Element. Designed specifically for the harshest chemical environments, this filter element offers exceptional resistance to acids, solvents, and high temperatures, ensuring reliable performance in critical processing applications. With annual exports exceeding US$5 million and a global presence across North America, Europe, Southeast Asia, and more, our products are trusted by industries worldwide for their durability and efficiency.
Our PTFE membrane coated fiber filter element is engineered to deliver superior filtration while withstanding corrosive chemicals that would degrade standard filters. The unique PTFE coating provides a non-stick, chemically inert surface that prevents clogging and extends service life. Whether you are filtering aggressive acids, organic solvents, or high-temperature process streams, this element maintains consistent flow rates and particle retention.
Key Features & Technical Specifications:
- Chemical Resistance: Excellent resistance to concentrated acids (e.g., sulfuric, hydrochloric, nitric), alkalis, and most organic solvents. Suitable for pH 0–14.
- High Temperature Tolerance: Continuous operation from -20°C to 260°C, with peak surges up to 280°C.
- Filtration Precision: Available in micron ratings from 0.5 to 100 microns, with customizable options to meet specific process requirements.
- Low Pressure Drop: The membrane-coated fiber structure ensures high porosity and minimal resistance, reducing energy consumption in filtration systems.
- Long Service Life: PTFE coating resists fouling and cake formation, allowing easy cleaning and multiple reuse cycles.
- Versatile Configurations: Offered in pleated, wound, or cartridge styles, with various end cap options (222, 226, DOE, etc.) to fit standard housings.
- Non-Contaminating: PTFE is FDA-compliant and inert, making it suitable for sensitive applications where purity is critical.
Typical Applications:
- Chemical processing: acid recovery, solvent filtration, catalyst removal
- Pharmaceutical manufacturing: active ingredient filtration, solvent purification
- Electroplating and metal finishing: acid bath filtration
- Petrochemical industry: hydrocarbon processing, corrosive gas filtration
- Environmental protection: wastewater treatment, fume scrubbing
