  • Improve performance by installing a larger filter bag

    YOU MIGHT NOT NEED a more powerful dust collector after all. That’s the word from woodworkers who’ve replaced the original equipment filterbags on their collectors with bags that are more efficient. You might ask, “What can be more efficient than the 1 micron bag that came with my collector?” The answer is a 1 micron bag that’s properly sized for your machine and ...

  • Advantages and basic facts for the use of Lenzing PROFILEN based filter media

    Normal PTFE filter bags have a very good chemical resistance but on the other hand they do not have a high dust separation efficiency. Lenzing PROFILEN® is a compromise between a high efficiency and a high flow rate after cleaning of gases with all the positive aspects of normal PTFE bags. Basics To acquire a better feeling and understanding for the advantages of Lenzing PROFILEN® it is necessary ...

  • To prevent blinding in dust collection systems, consider filter type, filter size and selection of the filter media used

    All dust collection systems, regardless of size, share a common problem—dust blinding. Simply stated, blinding is defined as when dust particles plug the holes in a filter and stop the flow of air through the filter, resulting in the dust collector performing poorly. All types of collectors, whether stand-alone units, cyclones or full-scale baghouses, are subject to blinding. To better ...

  • Solid / gas separation with fabric filters

    A myriad of filter media are utilized today for separation of particulate matter in industrial gas filtration applications. These media range from single use (deposable) to semi-permanent media and include fiber, fabric, ceramic, membrane, metal mesh, and sintered metal media. Semi-permanent media are usually cleanable, either on or off-line, and are primarily intended for long-term (up to ...

  • Beta ratios explained and applied to liquid filter selection

    Liquid Filter Beta Ratios: Absolute rated liquid filter selection is tied to the media micron rating, materials of construction, construction design, and particulate removal efficiency filter factor known as its Beta Ratio (Figures 1, and 2). Consider that Engineering and Purchasing usually see absolute rated liquid filter efficiencies from vendor data sheets and quotes listed at 99%, ...

  • Filter Your Air with Cartridge Dust Collector

    A cartridge dust collector uses filtering cartridges and is a self-cleaning dust collector. The cartridges it uses are made from synthetic fibers and cellulose that is treated chemically. This ensures the particles are efficiently collected without forming an excessive pressure drop in the system. Structure A cartridge dust collector uses an air-jet cleaning structure to preserve ...

  • The Use of Particulate Emission Monitors to Support Arrestment Plant Operation and Upkeep

    The operation of filtration type arrestment plant can be optimised by the effective use of Particulate Emission Monitors (eg Filter Leak Monitors and Filter Performance Monitors). Particulate Emission Monitors are installed throughout the broad spectrum of industrial processes to satisfy regulations (IPPC, Part B Guidance Notes, WID and LCPD) for emission limit enforcement. In addition, where ...

  • Ineffective cleaning in generic baghouses

    ABSTRACT: Background In a typical “generic” baghouse application, the cleaning is accomplished by back-flushing the filter with compressed air that travels through an orifice hole in a purge tube (blow pipe) and through a venturi. A typical generic cleaning system allows dust to be filtered at an air-to-cloth ratio of 5:1. That means for every 5 CFM of airflow, there is 1 square foot ...

  • Advantages of cleaning without a venturi in baghouse collectors

    ABSTRACT: Background The cleaning cycle is the most important part of the dust collector because it controls efficiency and media life. In order to clean a row of bags in a reverse pulse jet baghouse first the flow of filtered air must be momentarily stopped and then back flushed or “induce” air to knock the dust cake off the outside of the filter media. A venturi at the top of the ...

  • Let’s Talk About the Design of Cartridge Dust Collectors

    When it comes to choosing a cartridge filter, the choice usually depends on the application. Systems with finer particles require a cartridge filter, and these come in the choice of two. Surface and Depth-Type Filters A surface filteris ideal when filtering remains of similar-sized particles. Depth-type filters capture pollutants and particles ...

  • Improving the cleaning cycle in baghouse collectors

    ABSTRACT: Background The reverse pulse jet baghouse has been around for over 45 years and the cleaning cycle has not changed very much since that time. The cleaning cycle is the most important part of the dust collector because it controls efficiency and media life. In a generic baghouse, the cleaning system is comprised of a blowpipe that is located typically approximately three inches above ...

  • Air filtration applications for membranes

    Given their unique performance attributes membranes are finding use in a growing number of high efficiency air filtration applications. One example is in respirators and personal protective equipment. Applications where intense physical demands and risk of exposure to harmful contaminants are present demand the high efficiency / low pressure drop combination of expanded polytetrafluoroethylene ...

  • New Nozzle Technology “Cleaning More with Less”

    This technical paper will explain the new nozzle technology developed by Scientific Dust Collectors that allows high air-to-cloth ratio baghouses to use 80psig of compressed air instead of the industry standard 100psig.   The reverse pulse jet baghouse has been around for over 50 years and the cleaning cycle has not changed very much during that time. The cleaning cycle is the most important ...

  • Efficient Removal of Organic and Inorganic Suspended Solids

    ABSTRACT The Romans used sand as a filter media to treat their drinking water 2000 years ago. Centuries ago water was poured through layers of cloth to remove visible impurities in drinking water with fabric bags and paper cartridges soon following. Darcy employed sand beds in Dijon, France over 200 years ago to conduct his experiments for developing his famous equation to describe fluid flow ...

  • Understanding Crossflow Filtration

    There's a lot of attention being given to water availability and purity, with good reason. Obtaining enough water is a struggle in some areas. In others, water is tainted with contaminants. It is therefore predictable that regulations and economics will force careful water treatment and stress water re-use. Fortunately, there are water treatment methods that can help you meet the water quality ...


  • Waste Transfer Station Odours - Case Study

    Application Greenstar Ltd. who operate the large waste transfer station at Ballyogan needed to ensure working conditions inside the building were acceptable to the workforce and that the surrounding area did not suffer from odourous emissions.
