Featuring a single-layer, inherently hydrophobic Polytetrafluoroethylene (PTFE) membrane supported inside a rugged polypropylene housing, this filter provides a large 19.6 cm² effective filtration area (EFA). The extreme hydrophobicity of the PTFE substrate prevents ambient humidity or aerosol mist from wetting out the membrane, maintaining optimal, high-velocity airflow and preventing premature pressure drops. This model is equipped with universal stepped hose barb connections that interface cleanly with flexible laboratory tubing ranging from 1\/4 inch to 1\/2 inch inner diameter (ID).\u003c\/p\u003e\n\n\u003ch3\u003eTechnical Performance and Design\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eInherently Hydrophobic PTFE Membrane:\u003c\/b\u003e The 0.2 µm sterilizing-grade PTFE matrix naturally repels aqueous solutions and moisture droplets, serving as an absolute physical barrier to block aerosol tracking and bacterial bypass under both wet and dry operating environments.\u003c\/p\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003eBroad Chemical Compatibility:\u003c\/b\u003e Constructed entirely from premium fluoropolymer and polypropylene resins without internal adhesives or glues.
