Section 8 – Appendix
Dust Collection Terms & Definitions
Air-to-Cloth Ratio – Ratio of the volume of gas filtered (in ACFM) to the amount
of filter media (in square feet).
Cartridge Blinding – A condition where dust particles become embedded in the
fabric over time and are not removed by the cleaning mechanism. This results in
an increased pressure drop across the filter cartridge media.
Bleed Through – Small particles of dust that are able to migrate through the
filter cartridges.
Bridging – A material blockage across an opening such as a hopper or between
filter bags or cartridges.
Can Velocity – The upward velocity of air through a cross section of the dust
collector.
Clean Air Plenum – The area of the dust collector where the air passes through
after being filtered by the filter media.
Diaphragm Valve – A compressed air valve that provides a volume of high-
pressure air to clean the filter media.
Differential Pressure – The variance in pressure between two measured points.
On a dust collector this is generally measured on each side of the tube sheet to
indicate the condition of the filter cartridges. This is typically measured in inches
of water.
Dirty Air Plenum – The area of the dust collector where the filter media hangs
and the air has dust particulate in it.
Dust Cake – The normal build up on the outside of the filter media. A dust cake
is needed to provide the maximum filtering efficiency.
Filter Media – An air permeable material that provides a means to separate the
particulate from the air. This is usually a pleated cartridge.
Inches of Water – The standard unit of measurement for dust collector
differential pressure. A typical notation is 2” w.c. ( water column) or 2” w.g. (water
gauge).
