GORE® Membrane Technology versus Non-Membrane Media
Longer Bag Life, Lower Emissions Rates, Lower Pressure Drops, Better Gas Throughput
Non-Membrane Depth Filtration
Filtering Mode
- Dust is filtered inside of filter media
- Internal dust cake buildup required
- Particles enter into filter media and can pass through
- Might not filter finest particles
- Efficiency requires careful balance between filter, particulate, and system conditions
Cleaning Mode
- Difficult to remove particles, only surface dust cake is removed
- Dust deep inside media can cause higher Dp and blinding with time
- Dust buildup inside media can lead to emissions after cleaning

Membrane Surface Filtration
Filtering Mode
- Dust filtered at membrane surface
- No dust cake buildup required
- No particles enter backer
- Capable of submicron filtration
- Maintains capture efficiency over wide range of system conditions
Cleaning Mode
- Almost all dust falls off membrane surface
- Particles do not build up inside backer
- Surface is hydrophobic, even wet dust cakes can still be handled

GORE™ Membrane Efficiency and Versatility
Membrane (500x)


Surface Filtration
Uniform membrane structure allows higher efficiency.
Non-Membrane (500x)


Depth Filtration
Dust still penetrates into backer and is trapped.
