Step 1 – Filter Media Selection<\/h1>\n

Choose the media from which your filter bags will be constructed of based on the type of application they will be used for. Take the following things into consideration prior to selecting your filter media:<\/p>\n

\u2022\u00a0\u00a0\u00a0 Temperature – Do your bags need to withstand extreme temperatures?
\n\u2022\u00a0\u00a0\u00a0 Material – What is the filter being used for?
\n\u2022\u00a0\u00a0\u00a0 Chemistry – Can your filter withstand the chemical makeup of the dust particles
\nResistencia: \u00bfEs capaz el material del filtro de resistir la abrasi\u00f3n de las part\u00edculas de polvo?<\/p>\n

Choosing the correct filter media is an important and sometimes difficult process. To assist you in the identification of the right media for your bags, keep the following in mind: Filter bag performance is directly related to how well it can tolerate the environment in which it is being used. How efficiently it can remove the dust particles from its fabric and its ability to be cleaned by the dust collector is also important. You must first learn to identify the type of filter media currently used in your application. Below you will find a list of typical construction methods:<\/p>\n

\u2022\u00a0\u00a0\u00a0 Woven felts
\n\u2022\u00a0\u00a0\u00a0 Non-woven felts
\n\u2022\u00a0\u00a0\u00a0 Natural fibers
\n\u2022\u00a0\u00a0\u00a0 Synthetics (Thermoset or Thermoplastics such as Polypropylene “PPRO” – Polyphenylene sulfide “PPS” – Polyester “PE”)<\/p>\n

For additional information on media types please examine our Filter Fabrics Chart below. A simple test to determine if a material is a thermoplastic is to take a small swatch and put a flame to it. A thermoplastic material will begin to melt when exposed to direct heat. The selection criterion eliminates materials based on temperature and chemical characteristics. The first cut is usually made based on temperature. Then the chemical characteristics of the gas stream are considered to further refine the search. Next, the efficiency of the material further dictates the construction of the material such as the weight, oz\/sq. ft., fiber and surface treatments\/membranes. Last but not least, if there are still two or more candidates it comes down to a price versus performance trade off.<\/p>\n

Step 2 – Dust Collector Filter Measurements<\/h1>\n

Accurate measurements lead to the best fit. It\u2019s likely that your dust collector has been modified over the years due to permitting issues or changes in your process which called for a reconfiguration of the Baghouse. In this case OEM configurations will not fit and you will need to obtain accurate measurements for your filters before ordering replacement filter bags. If you currently have filter bags installed that are functioning properly, you can remove one of these bags to get the proper measurements for your replacement order. A spare bag that has not been used yet can also be measured if available. However, be sure to verify the bag measured is the same as the bags currently being used in the dust collector. If you are removing a used bag to measure, please be sure to use all necessary precautionary measures set in place prior to removal i.e. gloves, protective garments and respiratory equipment if needed. It is best not to rely only on the numbers off the unit of OEM filter specifications because of possible changes to the configurations. Of course the best solution is to mail the manufacturer a new or used bag that can be used a guide sample.<\/p>\n

Ancho plano:<\/strong> Place the filter on a flat surface such as a large table or cement floor. With the filter stretched out, press down on the side. Using a measuring tape, very accurately record the width. Be sure to hold the filter down firmly on an even surface when taking this measurement.<\/p>\n

Di\u00e1metro:<\/strong> When measuring the tube sheet hole of a pulse jet style dust collector, first make sure the hole has not been damaged or warped in any way. Clean the surface thoroughly with a wire brush then using a micrometer, measure the hole in both directions. If the measurements are at all different locate another hold and repeat this process.<\/p>\n

Longitud:<\/strong> Remove the filter from the unit. Preferably with the assistance of another person, stretch the filter out. While maintaining tension on the filter record the length from the longest point at each end using a measuring tape. Do not include and straps, metal caps or other hanging hardware in the measurement, just the length of the filter itself.<\/p>\n

Step 3 – Top & Bottom Construction<\/h1>\n

The top and bottom construction of a filter bag involves a variety of possible configurations. Identifying the type of cleaning process used by your dust collector will help to determine which configuration is needed. The most common types of dust collectors are “Pulse-Jet” “Shaker” “Reverse Air”. The chart below can help you identify which type of dust collector filter you are using.<\/p>\n

Filter Configuration Chart<\/h2>\n

Pulse-Jet Dust Collectors (Reverse jet)<\/strong> – Found in almost every industrial environment. They are the most popular design and are seen in nearly all industry segments. Pulse-Jet Units can be divided into two major groups Top load or bottom load units sometime called top entry (walk-in plenum) or bottom entry (common in bin vents) because of the point of entry used to change out the filters.<\/p>\n

Typical filter configuration for a top load unit:
\nSnap Band Top <\/em>(double-beaded ring)
\nDisk Bottom<\/em> (w\/o wear strip)<\/p>\n

Typical filter configuration for a bottom load unit:
\nRaw End Top<\/em>
\nDisk Bottom<\/em> (w\/o wear strip)<\/p>\n

Shaker Dust Collectors<\/strong> (Mechanical Cleaning)<\/strong> – Usually found in older applications where unscheduled down time is not a major concern.<\/p>\n

Typical filter Top Configurations
\nLoop Top
\nGrommet Top
\nStrap or Tail Top
\nMetal Hanger or Cap<\/em><\/p>\n

Typical Filter Bottom Configurations
\nCorded Cuff with Clamp
\nSnap Band <\/em>(Double-Beaded Ring)<\/p>\n

Reverse-Air Dust Collectors<\/strong> – Usually found in very large air handling environments such as power generation and cement plants although they do have uses in a variety of industries. Sometimes called a structural bag, these filters usually have a series of support rings spaced every few feet throughout the length of the bag.<\/p>\n

Step 4 – Additional Options<\/h1>\n

Ground Wires<\/strong> – Use to comply with Factory Mutual requirements for static dissipation. Ground wire can be made from stainless steel or copper however this technique only works on a localized area of the filter. For optimal static dissipation look at conductive fiber filter made with Epitropic or Stainless Steel fibers.<\/p>\n

Wear Cuffs<\/strong> – Used to combat abrasion at the bottom of the bag either from a sandblasting effect or from bag-to-bag abrasion due to turbulence in the bag house. Usually 2 to 4 inches in length and made of a material similar to that of the body of the filter bag.<\/p>\n

Special Finishes<\/strong> – There are many finish options that can be added to the filter media at the time it is manufactured. Please refer to the materials selection area for further details. If you want to order a specific brand or special type of finish please add that request into the additional comments section when ordering.<\/p>\n<\/div><\/section>","protected":false},"excerpt":{"rendered":"","protected":false},"author":2,"featured_media":6517,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[134],"tags":[38,53,39,40,54,55],"class_list":["post-762","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-dust-collection-101","tag-baghouse","tag-baghouse-filter","tag-dust-collection-blog","tag-dust-collector","tag-dust-collector-filter","tag-filter-bags"],"acf":[],"_links":{"self":[{"href":"https:\/\/baghouse.com\/es\/wp-json\/wp\/v2\/posts\/762","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/baghouse.com\/es\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/baghouse.com\/es\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/baghouse.com\/es\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/baghouse.com\/es\/wp-json\/wp\/v2\/comments?post=762"}],"version-history":[{"count":0,"href":"https:\/\/baghouse.com\/es\/wp-json\/wp\/v2\/posts\/762\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/baghouse.com\/es\/wp-json\/wp\/v2\/media\/6517"}],"wp:attachment":[{"href":"https:\/\/baghouse.com\/es\/wp-json\/wp\/v2\/media?parent=762"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/baghouse.com\/es\/wp-json\/wp\/v2\/categories?post=762"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/baghouse.com\/es\/wp-json\/wp\/v2\/tags?post=762"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
