In the event that an ember or other hot particle contacts the filter media, a hole can be burned in the astmm media severely hampering or completely eliminating its effectiveness. The nonwoven filter media of claim 16 including a scrim supporting said first fibers and ast, inorganic fibers. DavisTextile Research Journal, Southern Felt Company, Inc. The invention can also include a nonwoven filter media comprising: Digital Thickness Gauge with 16 mm footer and g weight. The scrim 18 is also shown disposed in the blend of fibers.

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 said inorganic fibers have a length of between 1 and 4 inches and a diameter of between 5 r461 30 microns.

FIELD OF THE INVENTION

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.

The nonwoven filter media of claim 1 wherein said filter media exhibits a residual d41 drop of less than Pa as measured by ASTM-D Using the acid resistance tensile test, the results are shown in FIGS. A sample of the blended fabric is cut into about a 2 inch by 6 inch piece in the machine direction.

The particulate then drops to the bottom of the hopper and can be removed from the hopper. The nonwoven filter media of claim 16 that is chemically treated. Device used to purify air and keep cleanly the duct of hot air system or central air exchanger. From the acid resistance tensile test, it can be seen that after the first two cycles, the sample can withstand over Ids of force.

Further, there can be chemicals in the air stream that are corrosive or otherwise damaging to the filter bag itself. Search Expert Search Quick Search. The invention can also include filter media comprising: This model is NOT recommended when testing requires specific test pressure. 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.

In one embodiment, an acid resistance tensile test is asfm with a testing machine suitable for ASTM D Air cleaner, filter element, and methods. Weights g less foot weight of 18g less spingle and Footer We Accept Printable Order Form.

This weight must be included when calculating test pressure MTG, with Dampener: The first polymer can have a denier of between 0. The filter media of claim 11 including a scrim supporting said first polymer fiber and said inorganic fibers. Cable and Software are offered as an option. 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 indicator is fitted on an 8 inch mm tall column to allow the indicator to be raised or lowered to accommodate different size astn specimens. A non woven filter media comprising: A SumoBrain Solutions Company.

Particulate in the gas stream are deposited on the filter bag.

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. To further the objectives above, this invention provides for non woven d416 media comprising: The first polymer can have a denier between 0.

The inorganic fibers are blended with the polyphenylene sulfide fibers and supported by a scrim. Refer to details below.

Filter Media – Southern Felt Company, Inc.

The denier of these fibers can be between 0. These heated particles can contact the filter bag and damage the bag rendered the filtering functionality ineffective. The nonwoven filter media of claim 1 including a scrim supporting said filter media. The filter media can have a thickness between 0. In terms of percentage strength loss, the sample exhibits virtually no loss f461 the first two cycles.

In one embodiment, the nonwoven filter media can be supported by a scrim that can be 1. Lead Time Varies, Please contact us for availability. With the above test parameter and tested filter media, the following results were achieved as shown in Tables 1 and 2: In several industries, baghouses having bag filters are used to remove dust and other particulates from the an air stream.
