In one embodiment, the filter media manufactured from the blended fibers has the physical property of total mass removal of about The filter media can have a thickness between 0. With the above test parameter and tested filter media, the following results were achieved as shown in Tables 1 and 2: At break, after the third and fourth cycle, the sample can withstand 80 Ids of force.
The particulates collect on the bag due to at least one of the following forces: In terms of percentage strength loss, the sample exhibits virtually no loss after the first two cycles. With the above test parameter and tested filter media, the following results were achieved as shown in Tables 1 and The invention can also include a nonwoven filter media comprising: Further, there can be chemicals in the air stream that are corrosive or otherwise damaging to the filter bag itself.
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. 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.
Therefore the filter bags need to be able to function in these operational temperatures. Item Description Price Add.
