Pocket or Envelope bags are in the shape of Pocket or Envelope hanging vertically with the support of Pocket or Envelope type Filter Cage in a pulse jet dust collector bag house. The envelope shape helps to remove more challenging dust cakes formed, this is because the envelope shape provides greater movement of the bag during filter pulsing. The dust collects on the outer surface which is also called dust cake and is cleaned by a high velocity pulse of gas which is released in regular interval. In order for gas to sustain the regular operation of Filtering and cleaning it’s very important to select the right fabric media and design to achieve maximum efficiency. We offer Pocket type bags in all major fabrics used industry wide making sure it’s suitable for the application and temperature.
