Filtration

Airborne contaminants can be subdivided into various sizes (expressed in µm). Each range of this subdivision requires a specific filtration method. Thus, a subdivision into coarse dust filters, fine dust filters and absolute filters takes place. To avoid rapid saturation of the "main filter" - which is relatively expensive - the structure of the filters in a plant is tiered.

There are several air supply systems, each with its own specific advantages. The main air supply systems are:

  • Open plenum systems
  • Systems with separated ducts
  • Systems with 'In-line housing'
  • Fan Filtermodule system
  • Satellite system
