2. Filtration Rules of Thumb
General: For peak output performance from a compressor, blower, vacuum
pump, engine, or any other machine that consumes air, one must have clean,
unrestricted air. Proper filtration can help stabilize the working environment within
rotating equipment even when the external conditions may be quite severe. A
critical component in creating the right working conditions is filter sizing. With the
properly sized filter, equipment will run smoothly over its entire expected
operating life.
A major factor in filtration and filter sizing is air velocity through the filter media.
Generally, the slower the velocity of air through a media the higher the filter
efficiency and, conversely, the lower the pressure drop. Therefore, the primary
goal in filter sizing is to optimize the velocity of air through the media (sometimes
called face velocity).
