Micron rated bag filters with Stainless steel ring sewn construction

Industrial Micron needle punched non woven liquid filter bag
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

1. 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).

2. 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.
