• How to Maintain your Dust Collector
  pressure drop because of the inherent permeability of the media. As the bags develop a dust cake, some particulate embeds itself into the filter media, increasing pressure drop accordingly. The filtering of the airstream through this accumulated dust cake provides high-efficiency collection of fine...
• Using MERV Ratings to Determine the Effectiveness of Industrial Dust Collectors - How Appropriate?
  the cleaning occurs during normal operation. The ever-changing dust cake (and its associated pressure drop) means that the efficiency of the filter is also ever-changing. Each time a filter is cleaned, the efficiency of the filters changes. The static conditions used in ASHRAE 52.2 cannot...
• Seamless Tube(R) Case History (.pdf)
  this problem. Seamless Tube(R) RT02 uses a 100% Polyester knit structure to maximize collection efficiencies, enhance air flows, reduce media drag and enhance dust cake release. Midwesco supplied 4200 Seamless Tube(R) RT02 bags, tensioning hardware, Leak Seeker(R) and PreKote(R). Midwesco personnel installed...

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...

  filter-cleaning system. It’s possible that the system is over cleaning and removing too much of the dust cake from the filter, reducing the media’s overall filtration efficiency. The most efficient filter has a dust cake, so if you see that the filters have almost no dust cake or none at all, leave the cleaning...
• Automated Dosing of Dry Treatment Chemical with Flexible Conveyor Improves Accuracy, Safety of Filtration System
  in a machine train that is 6 ft (1829 mm) wide and 27 ft (823 cm) long. When treatment of large (8-ft [244 cm]) tanks of water is required, Oberlin Filter adds a Flexicon bulk bag discharger to the DMaxTM filter system to deliver large quantities of dry chemicals. Enclosed, dust-free conveyor...
