NEW GORE® LOW DRAG Filter Bags for Carbon Black production
NEW GORE® Low Emission Filter Bags
Particle and Gas Filtration for Industrial Processes & Bag Houses
A carbon black manufacturer faced a need to maintain filtration emissions to the lowest level possible to ensure regulation compliance and increase energy production efficiency.
Chemical manufacturing is driven by throughput. In order to meet chemical productivity demands, manufacturers require components that function reliably at a steady rate, and filter bags are critical to their processes. Filter bags must often withstand constant exposure to aggressive environments, along with high temperature and humidity levels. They must endure mechanical stress from high dust loading and frequent cleaning cycles at high pressure — all while capturing as much chemical product as possible, day in and day out.
That is why discerning chemical manufacturers use GORE® Filter Bags. They count on us to reliably capture their high-quality chemical products while delivering the lowest cost of ownership. At Gore, we take pride in providing ePTFE filtration products and solutions that our customers value, offering cost-saving benefits such as …
- longer filter bag life
- less unscheduled downtime
- higher productivity
- lower emissions
Innovative Products for Chemical Manufacturers
GORE® LOW DRAG Filter Bags: Lower Resistance to flow has many possible benefits!
Optimizing production is the primary goal of many chemical manufacturers. While all GORE Filter Bags provide excellent product capture, GORE LOW DRAG Filter Bags can potentially increase your throughput. How?
The key is improved cleanability without sacrificing durability or particle capture efficiency, as shown in this short video.
Instead of the “blinding” effect, which causes an increase in resistance during the life of other filtration materials, GORE LOW DRAG Filter Bags maintain high airflow levels (or low baghouse differential pressure) throughout their useful life. For a chemical manufacturer where the baghouse is the bottleneck, this translates to increased throughput.
In fact, GORE LOW DRAG Filter Bags can be utilized in a variety ways for the benefit of chemical manufacturers. The most common benefits, as described further in this video, are…
- increased throughput
- higher airflow (higher productivity)
- lower differential pressure (dP)
- longer filter bag life
- less filter bags required
GORE LOW DRAG Filter Bags can be optimized to reduce your total cost of ownership by increasing product throughput; or, the baghouse can be optimized to increase the life of your filter bags.
GORE LOW DRAG Filter Bags — A Step Change for Carbon Black Production
GORE LOW DRAG Filter Bags are now available for use in carbon black applications, offering carbon producers the efficiency, high performance and low cost of ownership that other industries have experienced through GORE LOW DRAG Filter Bags.
These bags incorporate a new ePTFE membrane designed to drastically reduce the resistance to airflow in your baghouse. By optimizing airflow, the filter bags allow operations to run more efficiently with significant benefits for carbon black baghouse operators:
- Lower emissions and sifting, leading to consistent regulatory compliance and improved downstream energy recovery (read case history)
- Lower persistent differential pressure (dP), which enables longer bag life through reduced cleaning (read case history)
- Increased throughput and/or fewer required filter bags
Combining a robust filter bag design and Gore’s complete application and system optimization experience, GORE LOW DRAG Filter Bags enable plant operators to achieve extremely reliable operations that remain compliant, are easy to maintain, and have a low cost of operation.
Watch this video to see how GORE LOW DRAG Filter Bags improve baghouse performance in carbon black applications.

GORE® Low Emission Filter Bags - Durable seam-sealing technology for the most challenging particle capture applications
When filter bags are sewn, the stitch holes create tiny holes in the membrane, which can become a leak path for extremely fine or free-flowing particles. For applications in which this small level of emissions is unacceptable, Gore has developed GORE Low Emission Filter Bags. Each bag features a PTFE-based seam tape covering all seams where the filter bag has been sewn, closing all the stitch holes and preventing emissions from leaking through.
When exposed to high temperatures and harsh chemicals, other PTFE tapes will often peel or crack, sometimes making the dust leakage problem even worse than it would be without seam sealing. Our patented seam tape stays intact and in-place, lasting for the life of the filter bag. This truly innovative technology serves our customers well in applications such as these:
- maximizing capture of high value ($/kg) particulates
- maximizing capture of very fine or free-flowing particulates
- meeting stringent emissions regulatory limits
- contamination of sensitive downstream applications

Filtering Grindings of Titanium Dioxide
A producer of TiO2 in the United States installed GORE membrane/heavy-duty polyester felt filter bags. As a result, bag life extended to 9–18 months, as opposed to the 2-4 months experienced with previously installed, conventional filter bags. Energy savings due to low DP was about $2,000/year, emissions became virtually non-detectable with 0% opacity, and the improved product recovery provided over $10,000/year of additional salable products. Additionally, less downtime and improved airflow equated to a production increase of over 10%.
Carbon Black Dryer Exhaust Collector Filtering
A producer of carbon black was experiencing major operational problems, including high differential pressure, visible emissions, and bag failures every three to six months. We installed 100% PTFE GORE Membrane / GORE Filter Bags. As a result, our customer experienced 60 months of continuous, problem-free service, with excellent pressure differential (dP).
Sodium Silicate Spray Dryer Filtering
A sodium silicate manufacturer was experiencing restricted production rates. Differential pressure in excess of 7.5" H2O had caused the baghouse casing to collapse. Increased product throughput would require approximately a $1,000,000 U.S. expenditure to enlarge the baghouse and require up to 24 months to appropriate the funds and complete the construction.
Instead, we installed GORE Filter Bags (Aramid felt). As a result, our customer exceeded their production goals without paying to enlarge the baghouse. The bags have performed consistently well for the past 12 years, with scheduled changeouts every 24 months — though bag life has reached 30 months. Since installation of the first set of GORE Filter Bags, the airflow has increased 30%, the differential pressure has not exceeded 5.5" H2O and the product throughput has increased by better than 60%.
Pulse Jet Dryer Baghouse
GORE Acid Resistant Aramid Felt Filter Bags have been successfully used for many years in dryer baghouses across a broad range of titanium dioxide products. However, in one industrial pulse jet dryer baghouse, a new line of grades with a combination of smaller particle sizes and increased flow ability was penetrating through the filter bags’ stitch holes — reducing product capture, increasing emissions, causing unplanned downtime and decreasing bag life.
To fix the issue, GORE Low Emission Filter Bags were installed. Constructed specifically to capture any emissions that may leak through stitch holes, these filter bags feature GORE Seam Tape covering all of the stitched seams.
As a result of the switch to GORE Low Emission Filter Bags, the emissions were eliminated. Particulate capture increased, boosting the baghouse’s efficiency and productivity and filter bag life increased from 4 to 18 months.
Gore produces a wide range of filter bags that vary by material and resistance to temperatures, moisture, oxygen, acid and alkali.
We are offering the following innovative filtration solutions:
