PTFE Membrane
Looking for a reliable solution for the sterile filtration of air or gases? PTFE membrane filters are the industry standard in critical processes where moisture, microorganisms, and particulates must be excluded. Thanks to their hydrophobic properties, these filters repel water and allow only gases to pass through. They are ideal for applications in pharmaceuticals, food and beverage production, chemical processing, and laboratory environments.
PTFE membrane filters for reliable sterile air and gas filtration
What is membrane filtration and how does it work?
Membrane filtration is an advanced separation technique that uses a semi-permeable membrane to separate liquids or gases. This membrane allows certain particles (such as water molecules) to pass through while retaining larger particles, microorganisms, salts, or contaminants. The separation is based on size, pressure, or chemical properties.
How does membrane filtration work?
During membrane filtration, a liquid is forced through the membrane under pressure. Depending on the pore size of the membrane, unwanted particles are retained and removed from the flow.
Benefits of membrane filtration
- Highly accurate filtration
Retains microorganisms, particulates, and dissolved substances down to the molecular level. - Energy-efficient
Often more efficient than thermal separation methods. - Compact systems
Membrane filters require minimal space and are easy to integrate into existing processes. - Versatile applications
Suitable for food & beverage, pharmaceutical, chemical, and water treatment industries.
Applications of membrane filtration
Membrane filtration is widely used in:
- Pharmaceutical manufacturing – for sterile filtration of air, gases, and liquids.
- Food & beverage processing – such as wine clarification and milk filtration.
- Water treatment – to remove bacteria, viruses, and chemicals.
- Chemical processing – for purification of solvents and process fluids.
Why choose PTFE membrane filters?
PTFE (polytetrafluoroethylene) is a chemically resistant and hydrophobic material, making it ideal for sterile filtration. Its stable pore structure, temperature resistance, and pressure tolerance ensure long-term reliability—even in demanding conditions.
