Ultrasonic fully welded liquid filtration bag with plastic ring
used for oil filtration
The high quality engineering plastic is selected to make the
plastic collar with excellent physical properties and chemical
corrosion resistance.The handle on the bag opening is above the
liquid surface for easy replace the filter bag, and improve the
work efficiency. Plastic collar specially designed, can be applied
to almost of the bag filters on the markets at present.Any kinds of
specification 1-4 filter bags, one specification of us produced
fully welded liquid filtration bags with plastic collar can be
compatible with.

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.
The principle filtration --- liquid filter bag filtration
This kind filter is pressure filtration, the whole system includes
three parts: bag filter housing,supporting basket and filter bags.
The flow materials enter to the top of the filter housing, and flow
the inside of the filter bag to the outer side of the filter bag,
whole materials are uniformly distributed on the surface.The
particles in the liquid are captured inside of the filter bag, no
leakage, easy operation, high efficiency, big amount materials can
be treated, filter bag with long life span. It is energy saving
products in liquid filtration industry, can be applied for any
kinds of preliminary , middle and fine filtration.The filtration
system design needs to consider process conditions such as working
temperature, pressure , viscosity, flow rate, impurity types,
contents and particles size and so on , as well as storage volume,
opening method, planned filter bag replacement frequency and
production costs.
