These felt filter bags have sewn construction and a glazed finish
(except 51635K, which have no finish). Polyester felt bags are
general-purpose media bags manufactured with a single layer of felt
media. Heavy duty polyester felt bags filter heavy metallic
particles and extremely viscous liquids such as tar without
tearing. Interwoven polyester mesh provides extra strength to hold
heavy particles. Polypropylene felt bags are FDA compliant. Nomex
felt bags are for use in high temperature applications in the
Filter Bag Size
Micron Ratings— Absolute-rated filter bags will retain at least 90%
of particles of the specified micron size. All other bags will
retain particles, but not to any percent efficiency. Often referred
to as nominal rated. To achieve the desired filtration, select a
bag with a micron size smaller than the particles you want to
