Therefore the filter bags need to be able to function in these operational temperatures. No orders will ship and email response will be delayed during this time. The nonwoven filter media of ashm 16 including a scrim supporting said first fibers and said inorganic fibers.

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

The process of placing the sample in the 1N H 2 SO 4 solution then drying and cooling the sample defines one cycle. The first polymer can have a denier of between 0.

Contact us for more info. The nonwoven filter media of claim 16 including a first layer and a second layer asgm nonwoven filter media supported by a scrim. 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.

Device used to purify air and keep cleanly the duct of hot air system or central air exchanger. Refer to details below. 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 filter media of claim 11 wherein said tensile test is preformed according to tensile test ASTM-D At break, after the third and fourth cycle, the v461 can withstand 80 Ids of force. The fibers 14 with the larger diameter principally consist of polyphenylene sulfide and the fibers 16 with the smaller diameters are the inorganic fibers.


Cable and Software are offered as an option. 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.

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

The nonwoven filter media of claim 1 including a scrim supporting said filter media.


For those requiring data output for recording and quality documentation purposes, a serial output cable d4461 windows-based software program is optionally available. The nonwoven filter media of claim 2 wherein said scrim is a 1 to 6 ounce scrim. The inorganic fibers are blended with the polyphenylene sulfide fibers and supported by a scrim. The filter media of claim 11 including a scrim supporting said first polymer fiber and said inorganic fibers.

Weights g less foot weight of 18g less spingle and Footer Custom Weights and Footers can be made to meet a wide range of specifications. The particulate then drops to the bottom of the hopper and can be removed from d4611 hopper.

ASTM-D | Standard Test Methods for Felt (Withdrawn ) | Document Center, Inc.

Reticulated pore formers for ceramic articles. The filter media can have a thickness between 0. After the fifth and sixth cycles, the sample can withstand about 70 pounds of force.

The first polymer can have a denier between 0. These heated particles can contact the filter bag and damage the bag rendered the filtering functionality ineffective. Search Expert Search Quick Search. A filter media comprising: Gas having particles enters the baghouse through hopper 10 of FIG. To further the objectives above, this invention provides for non woven filter media comprising: The indicator d641 fitted on an 8 inch mm tall column to allow the indicator to be raised or lowered to accommodate different size test specimens.


Most baghouses use long, cylindrical filter bags or tubes made of fabric as the filter medium. In several industries, baghouses having bag filters are used to remove dust and other particulates from the an air stream. The particulates collect on the bag due to at least one of adtm following forces: Lead Time Varies, Please contact us for availability. The filter media of claim 11 wherein said filter media includes physical properties taken from the group consisting of: Thanks for your patience.

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 asrm filter bags. Digital Thickness Gauge with 16 mm footer and g weight. Using the acid resistance tensile test, the results are shown in FIGS. Particulate in the gas stream are deposited on the filter bag.

A sample of the blended fabric is cut into about a 2 inch by 6 inch piece in the machine direction. 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.

Click image for more info. With the above test parameter and tested filter media, the following results were achieved as shown in Zstm 1 and In one embodiment, an acid resistance tensile test is preformed with a testing machine suitable for ASTM D 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 invention can also include filter media comprising:
