Key Features & Technical Specifications
- PTFE Microporous Membrane: Provides high flow rates, low pressure drop, and excellent chemical resistance – ideal for aggressive solvents, acids, and bases.
- 0.45 μm Absolute Rating: Ensures removal of fine particles, bacteria, and particulates down to 0.45 microns, meeting stringent quality standards.
- 304 Stainless Steel Outer Support: Adds mechanical strength, prevents collapse under high differential pressure, and allows for easy cleaning and reuse.
- 20-inch (508 mm) Standard Length: Compatible with most industrial housings; customization available for other lengths.
- Max Operating Temperature 70°C: Suitable for hot liquid filtration without compromising membrane integrity.
- Low Extractables: PTFE is inherently inert, minimizing leaching of contaminants into the filtrate.
- Wide Compatibility: Works with pH 1–14 and various organic solvents.

- Cost Efficiency: Lower replacement frequency compared to disposable cartridges, and reduced downtime during changeovers.
- Versatile Compatibility: PTFE is chemically inert – it withstands aggressive solvents like acetone, toluene, and strong acids, making it ideal for chemical processing and pharmaceutical intermediates.
- High Flow & Low Pressure Drop: The microporous structure maintains high filtration efficiency while minimizing energy consumption.
- Temperature Resistance: Operates reliably up to 70°C, enabling hot filtration processes without membrane degradation.
Frequently Asked Questions (FAQ)
-
What is the difference between this PTFE cartridge and a polypropylene (PP) cartridge?
PTFE offers superior chemical resistance and temperature tolerance. PP cartridges are limited to 60°C and are not compatible with strong solvents. For aggressive media, PTFE is the recommended choice. -
Can this cartridge be sterilized or cleaned?
Yes, the 304 stainless steel support allows for autoclaving or CIP (clean-in-place) procedures. Please consult our technical team for specific parameters. -
What is the typical flow rate of a 20-inch 0.45 μm PTFE cartridge?
Flow rate depends on liquid viscosity, pressure, and housing design. Typically, it ranges from 10–30 L/min per cartridge for water at 25°C. Contact us for a detailed sizing calculation. -
Is the cartridge suitable for food and beverage applications?
Yes, PTFE is FDA-compliant for food contact. The stainless steel support is also food-grade. We can provide documentation upon request. -
What end cap configurations are available?
Common options include 222 O-ring, 226 O-ring, flat gasket, and spear end. Custom configurations are possible – please specify your housing compatibility. -
Can I use this cartridge for gas filtration?
While primarily designed for liquids, the PTFE membrane can also be used for sterile air/gas filtration at lower differential pressures. However, a dedicated gas filter may be more suitable. -
What is the maximum backwash pressure?
We recommend a maximum backwash pressure of 1.5 bar at 25°C. Higher backwash may damage the membrane. Our team can advise on the best cleaning procedure. -
How do I order the correct size?
Standard length is 20 inches. Also available in 10, 30, and 40 inches. Make sure to specify end cap type and O-ring material. We will confirm the order details.
