The certified digital indicator includes 3 SPC data output formats, English or Metric display, auto power off, and a left-hand lifting lever. 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.

The scrim 18 is also shown disposed in the blend of fibers. In one embodiment, an acid resistance tensile test is preformed with a testing machine suitable for ASTM D Southern Felt Company, Inc.

The first polymer can d4611 a denier of between 0. Further, there can be chemicals in the air stream that are corrosive or otherwise damaging to the filter bag itself. From these results, we can see that the clean gas concentration can be less than 0.

ASTM D – 93 Standard Test Methods for Felt (Withdrawn )

The nonwoven filter media of claim 1 including a scrim supporting said filter media. No orders will ship and email response will be delayed during this time. The first polymer can have a denier between 0. The filter media of claim 11 wherein said filter media includes physical properties taken from the group consisting of: The process of placing the sample in the 1N H 2 SO 4 solution then drying and cooling the sample defines one cycle.


For those requiring data output for recording and quality documentation purposes, a serial output cable and windows-based software program is optionally available. 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 traditional filter bags. The filter media can have a thickness between 0. 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.

Digital Thickness Gauge with 16 mm footer and g weight. Therefore the filter bags need to be able to function in these operational temperatures. 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.

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

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


Custom Weights and Footers can be made to meet a wide range of specifications. With the above test parameter and tested filter media, the following results were achieved as shown in Tables 1 and 2: Cable and Software are offered as an option.

E461 nonwoven filter media of claim 1 wherein said filter media exhibits a total mass removal efficiency of about 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 nonwoven filter media of claim 16 that is chemically treated. We are closed until January 2nd. Weights g less foot weight of 18g less spingle and Footer From the acid resistance tensile test, it can be seen that after the first two cycles, the sample can withstand over Ids of force. Using the acid resistance tensile test, the results are shown in FIGS. asfm

The fibers 14 with the larger diameter principally consist of polyphenylene sulfide and the fibers 16 with the smaller diameters are the inorganic fibers.

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