industrial bag filters used for multi bag filter vessel for liquid
filtration
We supply you with various of PP, PE,NMO ,Stainless steel wire mesh
and PTFE filter bags of silk materials, to meet your strictly
requirements for different filtration processes. Our micron grade
liquid filter bag can economically remove any solid form tiny
particles in the liquid flow. The solids in liquid can be
accurately fast, easily blocked inside the filter bag to keep
liquid clean. The filter bag structure is strong so that the liquid
can keep high speed flow.The selection of the filter bag should be
based on the liquid properties, and the chemical conditions at that
time.
Standard Non-woven needle micron felt liquid filter bag
Industrial standard polypropylene( PPSG) and polyester (PESG)
non-woven micron felt bag filters. Single side glazed to prevent
loose fiber migration. Graded pore depth filter media type. No
reinforcing insert.
Basic matrix configuration are designed upon more than 30 kinds of
fiber, it is key different from those air filtration felt which
made from about 3-5 kinds fiber.

How to replace the filter bag
Change-out Pressure Differential: The recommended bag filter
change-out pressure differential across the bag media is 0.10MPA (
15 PSI). Continuing beyond this point will result not only in rapid
flow rate reduction and contaminant unloading, but also increase
the risk of filter rupture. The max differential pressure allowed
is 0.23 MPA( 35PSI).
Removal of use filter: During operation, the filter media many be
embedded into perforated on the basket under excessive pressure,
making it difficult to remove the bag filter.When this happens,
don’t use excessive force to pull the bag, as it will break the
ultrasonic welding line and detach the seal ring form the bag body.
To safely remove the bag, shake the basket rapidly and then use a
spine motion to separate the bag from the basket, slowly pull the
use bag filter out.
