In the event that an ember or other hot particle contacts the filter media, a hole can be burned in the filter media severely hampering or completely eliminating its effectiveness. For those requiring data output for recording and quality documentation purposes, a serial output cable and windows-based software program is optionally available.

The nonwoven filter media of claim 16 including a first layer and a second layer of nonwoven filter media supported by a scrim. At break, after the third and fourth cycle, the sample can withstand 80 Ids of force.

The invention can also include a nonwoven filter media comprising: Optional presser foot diameters and related weights are available and custom sizes can be supplied to accommodate your specifications. The first polymer can have a denier of between 0.

The certified digital indicator includes 3 SPC data output formats, English or Metric display, auto power off, and a left-hand lifting lever. Some of the industries that use bag houses to remove particulates from the air stream include garbage incinerators, coal plants or boilers, furnaces for melting metal and other materials, pharmaceutical production food manufacturing, chemical production and cement plants.


Custom Weights and Footers can be made to meet a wide range of specifications. Further, there can be chemicals in the air stream that are corrosive or otherwise damaging to the filter bag itself.

Filter Media – Southern Felt Company, Inc.

DavisTextile Research Journal, In several industries, baghouses having bag filters are used to remove dust and other particulates from the an air stream. The inorganic fibers are blended with the polyphenylene sulfide fibers and supported by a scrim.

One significant risk associated with some applications is the risk of embers, heated particles or sparks being present in the hopper. This invention is directed to a filter media with improved heat resistance and performance properties, specifically, a filter media with improved cycle times, particulate removal d641, heat resistance and chemical resistance.

The sstm filter media of claim 1 wherein said filter media exhibits a residual pressure drop of less than Pa as measured by ASTM-D A non woven filter media comprising: A scrim can be included in the filter media to support the blended fibers. The nonwoven filter media of claim 2 wherein said scrim is a astmm to 6 ounce scrim. The scrim 18 is also shown disposed in the blend of fibers. In terms of percentage strength loss, the sample exhibits virtually no loss after the d641 two cycles.

The weight of the filter media can be between 5. A nonwoven filter media comprising: Cable and Software are offered as an option.

The gas is then directed through the filter bags 12 in a manifold where the filtered air exits the baghouse. No orders will ship and email response will be delayed during this time. Device used to purify air and keep cleanly the duct of hot sstm system or central air exchanger.

The filter media of claim 11 wherein said tensile test is preformed according to tensile test ASTM-D Item Description Price Add. This weight must be included when calculating test pressure MTG, with Dampener: A SumoBrain Solutions Company.

Using the acid resistance tensile test, the results are shown in FIGS. Weights g less foot weight of 18g less spingle and Footer From the acid resistance tensile test, it can be seen that after the first two cycles, the sample can withstand over Ids of force. Periodically, compressed air or other means is used to reverse the flow of gas through the bag filter which results in the filter cake or particulates being forced off the filter bags.

Particulate in the gas stream are deposited on the filter bag. In some applications, the gas includes particles that are heated such as in the coal, chemical, metal industries.

Thanks for your patience. The MTG Digital Contact Thickness Gage accurately measures thickness of textiles, non-wovens, technical fabrics and many other materials.
