SFB Series Standard Felt Liquid Filter Bags are made of high-quality polypropylene, polyester & Nomexfelt materials which provide consistent performance of liquid filtration in various of critical industries. Standard felt liquid filter bags offer efficient depth filtering at increased flow rates, and the glazed outer as well as the plain inner finish are to reduce fiber migration and enhance filtration performance. The collars and top rings of felt liquid filter bags ensure general compatibility with most of commercial bag filter housings in processing. Sewing or welded connection of polypropylene, polyester or Nomex makes the liquid filter bags suitable for different housings and purposes. Felt filter bags extend life time without media migration or bypass. Customized felt liquid filter bags are accepted for different requests in many industrial fields.

Pressure Drop vs Flow Rate of Standard Felt Liquid Filter Bags
| Working Principle of Standard Felt Liquid Filter Bags | ||
|
|
● The drawing is the working principle of standard felt liquid filter bags ● Dirty fluid flow through the plain inner finish layer and large particle block in surface ● Felt filter media traps contaminants within its depth, no sliding sideways during processing ● Clean fluid come out from glazed layer, high filtration efficiency and long service life with low cost |
