How Cartridge Air Cleaners Work

Contaminated air, typically dry dust and smoke, is drawn through high-efficiency cartridge filters, where the smoke and dust is collected on the outside of the cartridge media. Cleaned air goes through the cartridge to the clean air plenum, through a fan, and is typically exhausted back into the plant air or exhausted outside. The venturi pulse or other types of self-cleaning systems use compressed air to send air through the filter in the reverse direction, thus dislodging smoke and dust from the filter. On single cartridge collectors, the unit must be shut down for the cartridge to be cleaned. In the case of collectors that use multiple cartridges, its common to clean the filters while the system remains on and running. The solid pollutants are then collected in a dust drawer or barrel below the cartridge collector for periodic disposal. This method allows for multiple loadings and unloadings on the filter media, providing high efficiency and long filter life.

Cartridge Collector Facts

  • Cartridges will typically not clean back to “new” condition using compressed air. A dust layer or “dust cake” will develop on the surface of a new filter and remain there throughout the life of the filter.
  • Cartridges are most efficient not when first installed, but once they get dirty and develop a “dust cake”.
  • Smaller cartridge collectors can require more frequently filter cleaning than larger collectors, as the fans used in smaller collectors don’t always have enough static pressure or have poor performance characteristics at low airflow requirements.
  • Large centralized cartridge dust collection systems are no longer common. With LEAN manufacturing principles and keeping installation/operating costs to a minimum, smaller systems that handle a single work station or single work cell are most common.
