021Dust collector filters are one of the most popular and effective filtration systems for capturing industrial dusts and other small particulates. They are generally used for dry dusts in dry flow situations; however, some dust collector filters can be used in flow streams with a minimal amount of liquid present without adverse effect.

Continuous Cleaning Cartridges or Bag House Units

Dust collector filters come in two main categories: continuous cleaning cartridges, which do not utilize a fabric bag, and bag house units, which do. Bag house units often use a reverse-pulse system which sends air or gas through the bag house using a venturi nozzle while the bags are held in place in a wire cage. This pulsing air in turn dislodges dust particulates, allowing the dust collector filter to continue operating at optimal levels. Other systems may use a mechanical shaker or sonic vibration to clean dust.

The Many Media of Dust Collector Filters

Dust collector filters are available in a very wide range of different media types, which can be selected based on the needs of the system and the priorities of the client. Some common media types include:

  • Polyester
  • Cellulose
  • Fiberglass
  • Synthetic blends
  • Nomex
  • Teflon
  • PTFE membrane coated fabrics

The PTFE membrane coated fabrics allow the dust collector filter to meet high efficiency particulate arrestance (commonly referred to as “HEPA”) requirements.
