DN 180x420 mm length micron rated oil filter bags used for
industries purpose
Needle punched felt filtration bag with SS ring has big advantages
in the filtration efficiency and service life span. Due to the
using the advanced technology for design, the service life span of
the filter bag has greatly extended, avoid of fibers on the surface
dropped to the filter bag surface, and though special singeing and
polishing processing, the surface fibers are greatly reduced, but
still maintain its air permeability .SS steel ring sewn filter bag
with virgin fibers needle felts, creates stereoscopic 3D filter
layers, uses depth filtration principle, liquid flows through the
twists and turns on the path, the solid or gelling particles will
be intercepted and hold on the inner wall of the filter bag surface
and deep layer, so it has capture capabilities against the solid or
colloidal particles, such kinds filter bag also has the advantages
of good material thickness uniformity, good stability of pore size
and enhanced mechanical strength, better efficiency and long
service time and so on.

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.
