Nasal Spray-Pump Vents

Pharmaceutical and healthcare companies rely on POREX® Spray-Pump Primer Vents in spray-pump delivery devices (e.g., nasal sprays, topical sprays). Our vents can be designed to promote preservative-free packaging while maintaining sterility of the pharmaceutical agent by incorporating antimicrobial additives into the structure of the porous vent material. The vents provide optimized air flow resistance and performance as specified by the functional requirements of the specific device. They are designed for superior chemical resistance, physical and structural integrity, and are engineered to offer customized part geometries for varied device requirements.
