Featuring a hydrophobic PTFE membrane reinforced with polypropylene, these 50mm inline vent filters deliver fine particulate retention down to a 0.22um pore size while allowing air, gases, and non-aqueous fluids to pass without wetting the membrane. The transparent polypropylene housing is ultrasonically welded for leak-free performance, and 6 to 12mm stepped hose barb connectors on the inlet and outlet make them easy to integrate into inline venting and gas filtration setups. The large 50mm membrane provides a 19.6 cm² filtration area that supports high airflow while maintaining a low pressure drop, supplied nonsterile in a pack of 100.
Key PTFE Membrane Characteristics
- Hydrophobic PTFE membrane reinforced with polypropylene resists wetting, making it ideal for air, gas, and non-aqueous fluid filtration
- 0.22um pore size provides fine particulate and microbial retention for sterile venting and gas applications
- Broad chemical compatibility allows use across a wide range of aggressive solvents and gases
- 50mm membrane diameter delivers a 19.6 cm² filtration area for greater throughput and high air flow
- Reusable and autoclavable, with a maximum operating pressure of 3.5 bar
Key Construction Characteristics
- Transparent polypropylene housing, ultrasonically welded for leak-free performance
- 6 to 12mm stepped hose barb connectors on inlet and outlet
- Housing length 53mm, housing diameter 63mm
