Thumbnail Filmstrip of PTFE Vent Filters, 0.45um, 50mm, PP Housing, 6-12mm Hose Barb, Nonsterile, 100/Pk Images
Featuring a hydrophobic PTFE membrane reinforced with polypropylene, this 50mm vent filter delivers broad chemical resistance and high air flow for inline venting and gas filtration. The 0.45um membrane provides a 19.6cm² effective filtration area within an ultrasonically welded polypropylene housing, and 6 to 12mm stepped hose barb connectors make it easy to integrate into existing lines. The naturally hydrophobic media passes air and gases without wetting, making it ideal for venting and phase separation duties.
Key PTFE Membrane Characteristics
- Inherently hydrophobic PTFE that resists moisture absorption from air and gases, ideal for venting applications.
- 0.45um pore size for particulate removal from air and gas streams.
- Broad chemical compatibility with acids, bases, oxidants, and non-aqueous fluids.
- Reinforced with polypropylene for structural durability and consistent performance.
- Large surface area provides greater throughput and high air flow rate.
Key Construction Characteristics
- Polypropylene housing, ultrasonically welded for a reliable, leak-resistant seal.
- 6 to 12mm stepped hose barb inlet and outlet connections for inline setups.
- Effective filtration area of 19.6cm² across a 50mm membrane.
- Maximum operating pressure of 3.5 bar.
- Nonsterile, supplied 100 per pack; autoclavable at 121°C up to 10 times.
This vent filter maintains reliable air and gas flow while protecting sensitive environments from airborne particulates. The hydrophobic PTFE media and chemically resistant polypropylene construction support repeated autoclave cycles without compromising performance. The result is dependable venting and particulate control across laboratory and process applications.
