Dust collector filter bag Advantages
1. dust collector filter bag are carefully fabricated and sized to ensure ease of installation and
2. dust collector filter bags are designed to be mounted and gasketed firmly into place with a snap band, corded cuff, or clamp to ensure dust tight seal.
3. Various coatings and finishes can be applied to either side of the dust collector bag to enhance cleaning and efficiencies, as well as prolonging service life.
4. Groundwire, anti-collapse rings and other options can be easily incorporated into bag construction.
Filter bag is the“heart”of a dust collector,and it plays a very important part in dust collection.
Filter bag performance effects directly on the dust collecting efficiency.
Polyester needle felt is a widely used filter bag material which has great intensity and elastic
recovery,steady fiber dimension,good anti-wear property,large porosity,good air permeability,
long serving life,high dust collecting efficiency.It shows good mechanical properties and acid and alkali resistance
at normal temperature.
Polyester needle felt is a good option with good properties and appropriate price.
Characters of dust such as temperature,proportion,size,adhesion,concentration,humidity,
explosibility and filtration velocity should be considered before choosing filter bag to achieve an optimum efficiency.
dust collector filter bag Notices:
1. Materials avaliable: polyester, polypropylene
2. construction: welded or sewn
3. collar type: steel ring or plastic ring
4. finishing treatment: singed, calendared, heat set
5. Size available: standard and custom size.
