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 harshest environments.
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 filter.
