When Is An ePTFE Membrane Laminate the Right Solution for my Baghouse Air Pollution Control Application?

The Micronics Engineered Filtration team offers high-quality filter bags in a range of fabrics like aramids, fiberglass, polyester, PPS, and P-84, depending on your specific baghouse needs. Our filtration experts will help you choose the right filter bag measurements, construction, and determine whether a special finish is called for to optimize your dust collector’s performance. One of the many finishes that Micronics offers is known as an ePTFE membrane or membrane laminate.

What Is An ePTFE Membrane? “ePTFE” stands for expanded polytetrafluoroethylene and it is a microporous membrane that is bonded to the filtration side of the media to enhance bag performance. Enhanced operating performance with ePTFE membrane laminate may include enhanced emissions control, better bag cleaning, higher collection efficiency, and reduced energy costs.

Basically, when we select an ePTFE membrane laminate finish for your filter bag, it keeps the particulate out of the fabric of the bag, which helps to extend filter bag life in your baghouse and minimize the need for frequent bag changeouts.

What About Suitability for High-Heat or Chemically Aggressive Environment? 

When it comes to thermal and chemical compatibility, the substrate is the determining factor in the media selection process. For instance, in an application with inlet gas temperature consistently above 275°F, the ePTFE membrane may be laminated to PPS, Aramid, P-84, or fiberglass.

Tip:  It is important that you utilize the proper fabric best suited to your specific operating conditions and understand the full make-up of your gas stream, including hydrocarbons, as this may impact the ability to use ePTFE in your process.
