This is a selection method, not a universal rating table. It is informed by the JINLV Bag Filter Series catalogue and the available product drawings. Final equipment ratings, compatibility and operating procedures must be checked against the selected model and approved project drawing.
1. Define what the filter must remove
Describe the liquid, chemical concentration, viscosity at actual temperature, particle type and approximate solids loading. State the required downstream result and whether the bag is used for coarse protection, polishing or product recovery. A nominal micron number alone does not establish separation efficiency or dirt-holding life.
If the filter bag material is not fixed, select the media with the housing and basket. JINLV Filter Consumables lists bag-media routes separately from this equipment site.
2. Establish flow and pressure as separate design inputs
Provide normal, minimum and peak flow; inlet and downstream pressures; operating temperature; acceptable clean and terminal pressure loss; and whether the line can stop for bag replacement. Viscosity, solids loading, bag media and bag count all affect pressure drop and change-out interval.
3. Choose a serviceable housing structure
Use piping orientation and maintenance access to narrow the construction: side-entry or top-entry for their respective connection layouts; swing-arm, clamshell multi-bag or quick-open when lid handling and bag changes are central to the duty. Single-bag and multi-bag fully plastic constructions require a specific chemical, temperature and pressure review.
Do not multiply a brochure flow by bag count to size a vessel. Ask for a model-specific hydraulic and service review. Compare all seven constructions.
4. Verify the complete wetted and mechanical system
Check the vessel, basket/support, bag material and ring, gasket, seals, inlet/outlet connections, drain and vent against the liquid and cleaning chemistry. Confirm design pressure and temperature for the exact model, along with corrosion allowance or material documentation where the project requires it. Verify the lid opening envelope, bag lifting path, support loads and safe isolation/depressurization procedure.
Catalogue photographs show example constructions, not a promise that every option, dimension or certification applies to every delivered unit. The approved drawing and quotation should control the final interfaces and ratings.
5. Send a concise process brief
- Liquid and solids, including chemical concentration and viscosity
- Normal and peak flow, inlet pressure, available pressure drop and temperature
- Desired filtration result, existing bag type and change-out target
- Required wetted materials, seals and cleaning procedure
- Pipe sizes/standard, installation footprint and lid/maintenance clearance
- Drawing, certification or inspection requirements for this project
Missing data can be marked “to confirm”; this is preferable to assigning an unverified catalogue rating.
Turn the checklist into an equipment review
JINLV can review the available duty data and identify what must be confirmed before a quotation and approved drawing.
