Polytetrafluoroethylene (PTFE), Diameter 47 mm, Pore Size 0.22 μm, PP Laminated, GVS Group (CAT#: STEM-FC-1190-LC)

PTFE (fine powder resin) is expanded into a 3-dimensional weblike structure called PTFE which creates billions of microscopic pores. This structure utilizes the inherent hydrophobic (waterresistant) and non-stick nature of PTFE to remove particulate captured on the membrane surface. This allows air to pass easily through the membrane while allowing collection of particulate as small as 0.1 micron on its surface. PTFE membranes and laminates act as a consistent, temperature and chemical compatible barrier against microbes and particulate matter.
