A scrim can be included in the filter media to support the blended fibers. The weight of the filter media can be between 5. The nonwoven filter media of claim 2 wherein said scrim is a 1 to 6 ounce scrim. The first polymer can have a denier of between 0.

What is claimed is: The indicator is fitted on an 8 inch mm tall column to allow the indicator to be raised or lowered to accommodate different size test specimens. The nonwoven filter media of claim 16 including a scrim supporting said first fibers and said inorganic fibers.

Gas having particles enters r461 baghouse through hopper atm of FIG.

ASTM D – Standard Test Methods for Felt

A sample of the blended fabric is cut into about a 2 inch by 6 inch piece in the machine direction. Digital Thickness Gauge with 9. We Accept Printable Order Form. Further, there can be chemicals in the air stream that are corrosive or otherwise damaging to the filter bag itself.

The filter media of claim 11 wherein said filter media includes physical properties taken from the group consisting of: The following table illustrates the physical property benefit of the present invention when compared to a polyphenylene sulfide PPS fiber alone. With the above test parameter and tested filter media, the following results were achieved as shown in Tables 1 and 2: This weight must be included when calculating test pressure MTG, with Dampener: This invention relates to a composition of fibers and filter media made there from that provide for advantageous physical properties, especially for use with bag filters for a baghouse.

A non woven filter media comprising: In one embodiment, the polyphenylene sulfide fibers have a length of between 1 and 4 inches and a diameter of between 7 and 36 microns and said inorganic fibers have a length of between 1 and 4 inches and a diameter of between 5 and 20 microns. In some applications, the gas includes particles that are heated such as in the coal, chemical, metal industries.

Refer to details below. From the acid resistance tensile test, it can be seen that after the first two cycles, the sample can withstand over Ids of force.

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 improving the performance properties of traditional filter bags.

In terms of percentage strength loss, the sample exhibits virtually no loss after the first two cycles.

FIELD OF THE INVENTION

The nonwoven filter media of claim 1 wherein said filter media exhibits a total mass removal efficiency of about The samples are then tested using test method ASTM for strength and elongation with a lbs load. The filter media can have a thickness between 0.

In one embodiment, the filter media manufactured from the blended fibers has the physical property of total mass removal of about The certified digital indicator includes 3 SPC data output formats, English or Metric display, auto power off, and a left-hand lifting lever.

Thanks for your patience. The filter media of claim 11 wherein said tensile test is preformed according to tensile test ASTM-D A nonwoven filter media comprising: In one embodiment, the nonwoven filter media can be supported by a scrim that can be 1.

The nonwoven filter media of claim 1 wherein said filter media has a weight of between 5. Particulate in the gas stream are deposited on the filter bag. 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.

The nonwoven filter media of claim 1 including a scrim supporting said filter media. To further the objectives above, this invention provides for non woven filter media comprising: Therefore the filter bags need to be able to function in these operational temperatures. When the polyphenylene sulfide fibers and the inorganic fibers are blended and used to manufacture a filter media for a bag filter, the resulting filter can have the physical property of clean gas concentration of less than 0.

The first polymer can have a denier between 0. The particulate then drops to the bottom of the hopper and can be removed from the hopper. The nonwoven filter media of claim 1 wherein said polyphenylene sulfide fibers have a length of e461 1 and 4 inches and a diameter of between 7 and 36 microns and said inorganic fibers have a length of between 1 and 4 inches and a astn of between 5 and 30 microns.

The filter media of claim 11 including a scrim supporting said first polymer fiber and said inorganic fibers. Presser Foot “A” Dim. The invention can also include a nonwoven filter media comprising: The denier of the inorganic fiber can be between 0. We are closed until January 2nd. Reticulated pore formers for ceramic articles. Most baghouses use long, cylindrical filter bags or tubes made of fabric as the filter medium.

For those requiring data output for recording and f461 documentation purposes, a serial output cable and windows-based software program is optionally available. Custom Weights and Footers can be made to meet a wide range of specifications. One significant risk associated with some applications is the risk of embers, heated particles zstm sparks being present in the hopper.

Lead Time Varies, Please contact us for availability. The inorganic fibers are blended with the polyphenylene sulfide fibers and supported by a scrim.
