ASTM D MTG Material Thickness Gauge, D, D, ISO

Air cleaner, filter element, and methods. The nonwoven filter media of claim 16 including a first layer and a second layer of nonwoven filter media supported by a scrim. Astn orders will ship and email response will be delayed during this time. In several industries, baghouses having bag filters are used to remove dust and other particulates from the an air stream.

This weight must be included when calculating test pressure MTG, with Dampener: Particulate in the gas stream are deposited on the filter bag. The inorganic fibers are blended with the polyphenylene sulfide fibers and supported by a aastm.

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 atm between 5 and 30 microns.

In some applications, the gas includes particles that are heated such as in the coal, chemical, metal industries. Reticulated pore formers for ceramic articles. A non woven filter media comprising: The filter media of claim 11 including a scrim supporting said first polymer fiber and said inorganic fibers.

A SumoBrain Solutions Company. The nonwoven filter media of claim 1 wherein said filter media has a weight of between 5. The invention can also include a nonwoven filter media comprising: Device used to purify air and keep cleanly the duct of hot air system or central air exchanger.

Filter Media – Southern Felt Company, Inc.

The nonwoven filter media of claim 1 including a scrim supporting said filter media. Item Description Price Add. Most ashm use long, cylindrical filter bags or tubes made of fabric as the filter medium. We are closed until January 2nd. The nonwoven filter media of claim 16 including a scrim supporting said first fibers and said inorganic fibers.

In terms of percentage strength loss, the sample exhibits virtually no loss after the first two cycles. The nonwoven filter media of claim 1 wherein said filter media exhibits a total mass removal efficiency of about 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.

Digital Thickness Gauge with 16 mm footer and g weight. Gas having particles enters the baghouse through hopper 10 of FIG. This model is NOT recommended when testing requires specific test pressure. Optional presser foot diameters and related weights are available and custom sizes can be supplied to accommodate your specifications.

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.

FIELD OF THE INVENTION

One significant risk associated with some applications is the risk of ast, heated particles or sparks being present in the hopper.

The nonwoven filter media of claim 16 that has two or more fibers blended with the inorganic fiber. The gas is then directed through the filter bags 12 in a manifold where the filtered air exits the baghouse. A sample of the blended fabric is cut into d61 a 2 inch by 6 inch piece in the machine direction. The denier of the inorganic fiber can be between 0.

The following table illustrates the physical property benefit of the present invention when compared to a polyphenylene sulfide PPS fiber alone. The MTG Digital Sstm Thickness Gage accurately measures thickness of textiles, non-wovens, technical fabrics and many other materials. The first polymer can have a denier between 0. Weights g less foot weight of 18g less spingle and Footer The first polymer can have a denier of between 0.

In one embodiment, the filter media manufactured from the blended fibers has the physical property of total mass removal of about The weight of the filter media can be between 5. A spark can also create an undesirably opening in the filter bag. Some of the industries that use bag houses to remove particulates from the air stream include garbage incinerators, asym plants or boilers, furnaces for melting metal and other materials, pharmaceutical production food manufacturing, chemical production and cement plants.

At break, after the third and fourth cycle, the sample can withstand 80 Ids of force.

The filter media can have a thickness between 0. In the event that an ember or other hot particle contacts the filter media, a hole can be burned in the filter media ashm hampering or completely eliminating its effectiveness.

Custom Weights and Footers can be made to meet a wide range of specifications. Click image for more info. With the above test parameter and tested filter media, the following results were achieved as shown in Tables 1 and Click for automatic bibliography generation. A filter media comprising: The fibers 14 with the larger diameter principally consist of polyphenylene sulfide and the fibers 16 with the smaller diameters are the s461 fibers.

The following description is better understood with reference to the incorporated drawings which are part of the description of the invention:. The nonwoven filter media of claim 1 wherein said filter media exhibits a residual pressure drop satm less than Pa as measured by ASTM-D
