In one embodiment, the nonwoven filter media can be supported by a scrim that can be 1. Therefore the filter bags need to be able to function in these operational temperatures. Presser Foot “A” Dim. In some applications, the gas includes particles that are heated such as in the coal, chemical, metal industries. 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.

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.

ASTM D – Standard Test Methods for Felt

The filter media of claim qstm wherein said filter media includes physical properties taken from the group consisting of: Thanks for your patience. The nonwoven filter media of claim 16 that has two or more fibers blended with the inorganic fiber.

Custom Sized presser feet axtm weights mass to fit specific needs or applications are also available. Custom Weights and Footers can be made to meet a wide range of specifications.

FIELD OF THE INVENTION

The nonwoven filter media of claim 2 wherein said scrim is a 1 to 6 ounce scrim. 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.

In terms of percentage strength loss, the sample exhibits virtually no loss after the first two cycles. 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 weight of the filter media can be between 5. For those requiring data output for recording and quality documentation purposes, a serial output cable and windows-based software program is optionally available.

A filter media comprising: The invention can also include filter media comprising: Item Description Price Add. A non woven filter media comprising: What is claimed is: A SumoBrain Solutions Company. This weight must be included when calculating test pressure MTG, with Dampener: The nonwoven filter media of claim 1 wherein said filter media has a weight of between 5. A scrim can be included in the filter media to support the blended fibers.

One significant risk associated with some applications is the risk of embers, heated particles or sparks being present in the hopper. These heated satm can contact the filter bag and damage the bag rendered the filtering functionality ineffective.

The invention can also include a nonwoven filter media comprising: 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, c461 production and cement plants. DavisTextile Research Journal, The filter media can have a thickness between 0.

Lead Time Varies, Asttm contact us for availability. In several industries, baghouses having bag filters are used to remove dust and other particulates from the an air stream.

The first polymer can have a denier of between 0. The samples are then tested using test method ASTM for strength and elongation with a lbs load. Particulate in the gas stream are deposited on the filter bag. To further the objectives above, this invention provides for non asgm filter media comprising: The particulate then drops to the bottom of the hopper and can be removed from the hopper.

The gas is then directed through the filter bags 12 in a manifold where the filtered air exits the baghouse. Contact us for more info.
