Description
Standard Felt Liquid Filter Bags are made of high quality polypropylene, polyester & Nomexfelt materials which provide consistent of performance of liquid filtration in various of critical industries. Standard felt liquid filter bags offer efficient depth filtering at increased flow rates, glazed outer and plain inner finish to reduce fiber migration and enhance filtration performance.
Feature
1. Free silicone construction and wide chemical compatibility
2. Ratings of felt filter bags can be made from 1 to 300 micron
3. High dirt holding capacity, increasing efficiencies by preventing by-pass
4. High flow rate and low pressure drop media with consistent of performance
5. Glazed finish on polypropylene, polyester & Nomexfelt reduces fiber shedding
6. Sewn or fully-welded construction with steel O-rings or molded plastic snap seal rings
7. Liquid filter bags are made of 100% FDA approved polypropylene, polyester & Nomexfelt materials
Application
1. Electronics
2. Oil Refinery
3. Paints and Inks
4. Pre RO Filtration
5. Food & Beverage
6. Chemicals & Solvents
7. Petrochemical Process
8. Waste Water Treatment

Tech Support
| 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 | |
