The addition of PTFE membrane to standard filter fabrics will on average lower initial permeability from 30-60 CFM to 5-15CFM (depending on the fabric substrate and type of PTFE membrane). Under normal conditions Baghouse.com PTFE membrane filters will operate at 0.5in pressure drop at a 6:1 air-to-cloth ratio.

1. Sampler: PTFE laminated membrane filter, 2-µm pore size, 37-mm diameter (Zefluor, Membrana Inc., Pleasanton, CA; Gelman Sciences, or equivalent) backed by a gasket 37-mm OD, 32-mm ID, cut from a cellulose support pad (SKC, Inc. or equivalent) in plastic filter holder. 2.

PTFE (Polytetrafluoroethylene) Membrane Filters. PTFE filters are the versatile choice for size-selective samplers. The material's unique properties make it ideal for gravimetric, chemical, and/or microscopic analysis of sample particulate. PTFE filters are used for aerosol sampling, air venting and gas filtration.

POREX® plastic filter housings are self-contained preliminary filters for both gases and fluids. Designed to protect vacuum equipment, pneumatic controls units, pumps and motors from corrosion and chemicals, our plastic filter housings are an economical pre-filtration alternative for potable water and reverse osmosis systems.

Product Description. AG4502550. This is a 25 mm Hydrophilic Pure Silver membrane filter with a 0.45 um ( 0.45 micron filter ) pore size. Used for air monitoring of carbon black, coal tar products, coke oven emissions & silica. Referenced by NIOSH for collecting airborne contaminants.

PTFE membrane filters are among the most efficient industrial air filters. PTFE-coated filters are often used in dust collection systems to collect particulate matter from air streams in applications involving high temperatures and high particulate loads such as coal-fired power plants, cement production and steel foundries.

PTFE: Our PTFE sampling membranes are naturally chemically resistant, making them ideal for sampling in harsh environments. We offer unsupported PTFE filters for NIOSH-method 5013 testing, PTFE filters with laminated support for polynuclear aromatic hydrocarbon testing to NIOSH 5506 and 5515 standards, PTFE filters with a bonded PMP support

Due to its strength and broad chemical compatibility, PTFE is commonly used in membrane filters. While PTFE is known for its high strength, the addition of a high-density polyethylene (HDPE) backing offers improved filter handling characteristics. Hydrophilic LCR and Omnipore™ PTFE membranes are typically used for filtering aqueous solutions.
