Dual Flow Filter Bag
Our Dual Flow filter bag upgraded based on traditional standard filter bag. Fully welded or Stitched an inner filter bag together with the traditional standard filter bag. When liquid flows into dual filter bag, it can filter the liquid from the traditional standard filter bag outward and from the inner filter bag inward, so as to filter liquid from the filter bag inward and outward, that is called Dual-flow.
Compared with the traditional standard filter bag, filtration area of our Dual Flow filter bag increased by 75%~80%; Amount of contaminants collected increased significantly; Double filtration efficiency; The service life of Dual-filter bag is more than 1 times that traditional standard filter bag, maximum up to 5 times; The filtration cost is reduced by several times.
Our Dual Flow filter bag is applicable to all traditional bag type liquid filter housing. It can be used by simply upgrading the traditional filter basket, only welded an inner basket into traditional filter basket.
| Feature | Description |
|---|---|
| Excellent Flow Characteristics | 1. Dual-directional flow allows both the inner and outer filter bags to participate in filtration simultaneously, potentially doubling the flow rate. 2. Helps reduce the number of bags required in multi-bag housing systems. 3. Allows smaller and more cost-effective housings to be considered for new filtration systems. 4. Maintains a low differential pressure level to support efficient use of the available filter area. 5. Improves filtration speed and may increase customer productivity. |
| Increased Surface Area | Provides approximately 75%–80% more filter media than a standard-size filter bag, according to the source material. |
| Large Contaminant Retention | Increases the amount of contaminants collected during filtration. |
| Long Service Life | Provides 2–5 times the dirt-holding capacity of a standard-size filter bag, with at least twice the service life and fewer filter change-outs, depending on operating conditions. |
| Reduced Hold-Up Volume | The two-cylinder design retains less fluid, making filter change-outs easier. A 67% reduction in hold-up volume is stated in the source material and may help reduce product loss and disposal costs. |
| Wide Compatibility | Existing ordinary filter bags can be upgraded to Dual Flow Filter Bags by installing a compatible Dual Flow basket, helping reduce operating costs for existing systems. |
| Material Options | Polypropylene, polyester, extended-life, nylon mesh and oil-adsorption media options are available. |
| Basket Options | Dual Flow baskets are available in SS304 and SS316 and are designed for compatible traditional bag filter housings. |
| Micron Ratings | Nominal micron ratings from 0.2 to 1200 μm are listed in the data sheet. |
| Ring and Collar Options | Ring and collar options are available for different housing connections. |
