We are a manufacturer of filter bags with 0.5 micron, 1,5,10,25,50,100,200-600 micron.

Inside the bag filtration system,the filter bag is supported by an inside metal basket.The incoming fluid is to flow out after filtered by the bag,thus the impurity is intercepted in the filter bag.You can continue to use the filter system after changing the filter bag.It is a trend for the bag filter to replace partly the cartridge filter.The small filter bag can filter large amount of liquid.
The filter bag is key to filtering.According to the result of research from a famous company, for over 10 years,filter bags have been a critical component of filtration systems worldwide.

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. Nomex felt bags are for use in high temperature applications in the harshest environments.
