The hydrophobic PTFE membrane filters are made of polytetra-fluorethylene (PTFE) only and are therefore permanently hydrophobic. Unlike hydrophilic filter types, they are not wetted by air humidity.

Oct 10, 2011 · Introduction to PTFE Membranes Classic Filters first introduced PTFE membranes in 2002. They are most commonly used in sample systems to protect expensive and sensitive analytical equipment. Because they are hydrophobic water is repelled from the surface and pores of the membrane and cannot pass through.
PTFE membrane can withstand temperatures up to 500°F (260°C). PTFE membrane filters also are useful in high humidity environments. When moisture enters into a gas stream, it often times causes dust particles to become “sticky” and form agglomeration, which is a serious operational problem in many dust collection systems.

Feb 28, 2022 · The PTFE membrane filters are made of hydrophobic, non-woven and 100% pure PTFE material. The EZFlow’s 3. Filters out particles as small as 0.3 microns and it offers exceptional flow rates in excess of 3000 liters per hour (LPH) with adequate fine particle retention at 1 micron or less for total particulate removal.
Foxx Life Sciences. EZFlow 25mm, 47mm, and 90mm membrane disc filters are used to retain particles or microorganisms by surface capture. The membrane disc filters are available in 0.22µm or 0.45µm pore sizes. The Hydrophobic PTFE membrane is bonded to a polypropylene support and due to its extreme chemical.
PTFE (Polytetrafluorethylene). The hydrophobic nature of teflon and its broad chemical compatibility make it the filter of choice for filtration of air and gases, for use as vents and for clarification of acids, bases and solvents. The teflon membrane needs to be prewet with alcohol before aqueous solutions can be filtered. To overcome problems
Unlaminated PTFE Membrane Filter Specifications Performance by Pore Size Notes: 1. Airflow values calculated assuming linear relationship between volumetric airflow and differential pressure. 2. Water flows measured after prewetting with alcohol and calculated assuming linear relationship between flow and differential pressure. 3.
