PTFE sintered filter cartridge

The PTFE sintered filter cartridge, also known as polytetrafluoroethylene sintered filter cartridge, is made from pure PTFE material, sintered at high temperature and pressure. As a result, this filter cartridge exhibits strong resistance to acids and alkalis, high filtration strength, and toughness. Additionally, it can withstand temperatures up to 200°C. The PTFE filter cartridge is available with standard M20, 222, and 226 interfaces, which are interchangeable with other filter cartridges. It features flat push and pressure plate interfaces suitable for precise dimensions and steam filtration, and can be customized to various interface types as per requirements. The basic parameters are as follows:

Diameter: ∮20, ∮25, ∮30, ∮35, ∮40, ∮45, ∮50, ∮60

Length: 5", 10", 20", 30", 40"

Filtration accuracy: 0.3um, 0.45um, 1um, 3um, 5um, 10um, 20um

Advantages of PTFE sintered filter cartridge:

1.Resistant to strong acids and alkalis

2.Withstands high temperatures up to 200°C, suitable for steam sterilization and steam filtration

3.High porosity: While typical metal sintered filter cartridges have a porosity below 30%, PTFE sintered filter cartridges have a porosity of over 50%, allowing for increased fluid flow with the same filtration area

4.Smooth outer surface: The outer surface of the filter cartridge is smooth, preventing impurities from adhering to it. The high filtration accuracy on the outer surface and lower accuracy on the inner layer make cleaning easy and thorough, resulting in excellent cleaning efficiency and long service life.

5.High strength and toughness: The filter cartridge is highly resistant to breakage, solving the problem of significant losses caused by filter cartridge breakage.

6.High filtration accuracy: PTFE sintered filter cartridges can achieve filtration accuracies as low as 0.3um, even below 0.1um, surpassing typical metal filter cartridges. The combination of high filtration accuracy and porosity ensures good fluid flow under high filtration accuracy conditions.

7.No particle shedding: Both the inner and outer surfaces of the PTFE sintered filter cartridge are smooth, and thorough sintering at high temperatures and pressures prevents particle shedding during use, avoiding fluid contamination. Therefore, it is widely used in security filtration in industries such as water purification, pharmaceuticals, and food processing.

8.Strong ozone resistance: Thorough sintering at high temperatures and pressures provides the filter cartridge with stronger ozone resistance compared to PTFE folded membranes, making it widely applicable in industries such as pharmaceuticals, water purification, and food processing for ozone gas diffusion and sterilization filtration.

The PTFE sintered filter cartridge finds wide applications in industries such as pharmaceuticals, chemical engineering, synthetic fibers and textiles, wastewater treatment, light industry, food processing, petroleum, and more.For further inquiries about PTFE sintered filter cartridges, please contact Shanghai Sffiltech Co.,Ltd Consulting.
