Roto-Pulse Dust Collectors

For Process Dust and Powder, Welding Smoke and Fumes, and Metalworking Dust(by Micro Air)


Micro Air® dust collectors utilize cartridge filtration and are available in a large range of configurations up to 24 cartridge models. All are sized and rated for the proper air-to-cloth ratio to solve a wide variety of applications such as weld smoke, powder dust, grinding dust, paper dust, etc.

Key to our models is a revolutionary new cleaning system called Roto-Pulse™. This is an on line system that continually cleans the filters with a revolving, compressed air driven, tube. As air enters the tube, the force of the pulse causes the tube to rotate. While spinning, air exits the pre-drilled holes in the tube. The result is that air hits the entire inside of the cartridge, pulsing dirt particles away from the filter for a much more efficient cleaning cycle.

Micro Air® dust collectors are designed and manufactured with standard features that set them apart from the competition. These include:

  • Roto-Pulse™ Cleaning: Provides a much more efficient cleaning cycle for increased air flow and longer cartridge life.
  • Gravity Flow Design: Dirty air always flows across the filters from top to bottom utilizing the natural downward force of gravity to get the particles to the filtration.
  • Compact Design: A small footprint of only 42" x 48" allows Micro Air dust collectors to be located in virtually any area.
  • Easy Maintenance and Installation: All electrical and air connections are outside the cabinet for easy installation and maintenance.
  • After-Pulse is Standard: Micro Air provides an after-pulse cleaning cycle in addition to automatic on-line cleaning. This allows the unit to pulse the cartridges after power is shut off for an effective cleaning at the end of a shift.
  • Complete Single-Source System Design: We can design and provide a complete dust control system including the collector and the ductwork to solve your particular problem. This is your assurance of the best possible total system supplied from a single source.
  • In addition to our standard features, the model RP dust collectors have a broad range of options including explosion vents, HEPA after-filters, low profile options, a variety of different cartridges, and weather proof kits.

Roto-Pulse Filter


The exclusive Roto-Pulse™ self cleaning cartridge filters allow maximum filtration efficiencies with product reclamation and extended filter life.

The Roto-Pulse™ self-cleaning cartridge system offers a smaller footprint, efficiencies up to 99.99% and a more cost effective solution than those using reverse or jet pulse cleaning. This is done by cleaning 100% of the filter rather than 60-70% typical with traditional methods. Effectively, Roto-Pulse provides more continuously cleaned filter area than the competition and can extend filter life significantly as well.
