The particulate then drops to the bottom of the hopper and can be removed from the hopper.

Filter Media – Southern Felt Company, Inc.

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. We Accept Printable Order Form. In several industries, baghouses having bag filters are used to remove dust and other particulates from the an air stream. The nonwoven filter media of claim 16 that has two or more fibers blended with the inorganic fiber. Presser Foot “A” Dim.

The following description is better understood with reference to the incorporated drawings which are part of the description of the invention:. A non woven filter media comprising: From these results, we can see that the clean gas concentration can be less than 0. Thanks for your patience.

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 awtm, chemical production and cement plants. Optional presser foot diameters and related weights are available and custom sizes can be supplied to accommodate your specifications.



This weight must be included when calculating test pressure MTG, with Dampener: The denier of these fibers can be between 0.

The inorganic fibers are blended with the polyphenylene sulfide fibers and supported by a scrim. The filter media of claim 11 wherein said tensile test is preformed according to tensile f461 ASTM-D Tank Pressure 5 Bar 4.

This model is NOT recommended when testing requires specific test pressure. After the fifth and sixth cycles, the sample can withstand about 70 pounds of force. The weight of the filter media can be between 5.

Air cleaner, filter element, and methods. At break, after the third and fourth cycle, the sample can withstand 80 Ids of force.

A scrim can be asym in the filter media to support the blended asttm. Contact us for more info. The certified digital indicator includes 3 SPC data output formats, English or Metric display, auto power off, and a left-hand lifting lever.

The nonwoven filter media of claim 16 that is chemically treated. The particulates collect on the bag due to at astn one of the following forces: Weights g less foot weight of 18g less spingle and Footer The nonwoven filter media of claim 16 including a first layer and a second layer of nonwoven filter media supported by a scrim.


To further the objectives above, this invention provides for non woven filter media comprising: Custom Weights and Footers can be made to meet a wide range of specifications. The nonwoven filter media of claim 1 wherein said polyphenylene sulfide fibers have a length of between 1 and 4 inches and a diameter of between 7 and 36 microns and d41 inorganic fibers have a length of between 1 and 4 inches and a diameter of between 5 and 30 microns.

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 efficiency, heat resistance and chemical resistance. Therefore, it would be advantageous to have a filter bag for a baghouse that was resistant to heated particles and corrosive chemicals while maintaining or ast, the performance properties of traditional filter bags.

A nonwoven filter media comprising: The following table illustrates the physical property benefit of the present invention when compared to a polyphenylene sulfide PPS fiber alone. The nonwoven filter media of claim 1 wherein said filter media exhibits a total mass removal efficiency of about
