Hydrophobic PTFE Membrane Vents for IV Filters - Oleophobic Solutions from China Suppliers & Factory
Product Introduction
Hydrophobic PTFE (Polytetrafluoroethylene) micro pore membrane is an ideal venting membrane for medical IV filters. It power poses an excellent performance in medical applications. Its Hydrophobic properties make itself used as a perfect venting filtration media for IV filter or other medical devices. Air elimination is a necessary feature of infusion filters which have self-venting function. It allows the passage of air that has been entrapped in the intravenous line or filter and ensures that only clean air-free fluids reach the patient's bloodstream, and keep smooth, accurate, and safe infusion therapy.
Oleophobic PTFE membrane is highly recommended for compatibility with lipids or alcohol-based drugs (chemotherapeutics) delivery in infusion therapy.
By using 1.0μm venting membranes, excellent air-flow speed is key performance which improve the efficiency of elimination of infusion set and filter. 0.45μm venting membranes bring aerosol bacterial interception characteristic which intercept particles, microorganisms, bacteria in the air. Ensure the safety of infusion therapy. And 0.2 μm is the best choice of 0.2μm IV filters because of its necessity safety reasons.
According to the performance requirements by the users, ePTFE membrane has a wide range of customized options of pore size and airflow rate requirements because of its expanded structure. Meanwhile, additional oleophobic property is highly recommended for compatibility with lipids and alcohol-based drugs delivery in infusion therapy, ensuring long lasting venting performance.

Performance
Applications
- IV filters’ venting
- Gas filtration
- Bacteria interception
- Air-liquid separation
- Drainage bag/bottle
- Aerosol & microorganisms interception
- Medrad (high pressure injector) venting
- Humidifier bottle bacteria venting
- Spike & caps bacteria venting
Warning
- Handle with care to avoid damaging the filter material.
- Sterilization by irradiation is not acceptable.
- Do not use glue or cyclohexanone for adhesion as it can clog the material itself, preventing gas from passing through.
- Avoid contact with alcohol or high-permeability solvents, otherwise, the material will become hydrophilic before it is fully dried (oleophobic ePTFE membrane does not have this issue).

Frequently Asked Questions (FAQ)
What is the primary function of the Hydrophobic PTFE membrane in IV filters?
The main function is to act as a venting filtration media that allows entrapped air in the intravenous line or filter to escape while ensuring that only clean, air-free fluids reach the patient's bloodstream.
When should an Oleophobic PTFE membrane be selected over a standard Hydrophobic one?
An oleophobic PTFE membrane is highly recommended when the infusion therapy involves lipids or alcohol-based drugs (such as chemotherapeutic agents) to ensure long-lasting venting performance and compatibility.
How do the different pore sizes (1.0μm, 0.45μm, 0.2μm) affect performance?
1.0μm membranes offer high air-flow speed for efficient air elimination. 0.45μm membranes provide aerosol bacterial interception to block particles and microorganisms. 0.2μm membranes provide the highest level of safety and bacterial retention required for critical IV filters.
Can I customize the thickness and pore size of the ePTFE membrane?
Yes, because of its expanded structural properties, the ePTFE membrane has a wide range of customizable options for pore size, thickness, and airflow rate to meet specific application requirements.
What sterilization and chemical restrictions apply to PTFE venting membranes?
Sterilization by irradiation is not acceptable. You must avoid using glue or cyclohexanone for adhesion to prevent clogging. Additionally, avoid contact with alcohol or high-permeability solvents unless you are using the oleophobic version.
