Liquid Filter Bag Size Chart (#1–#5): JINLV Catalog Reference
Compare bag numbers, dimensions, filtration area and catalog reference flow. This is not a universal cross-brand dimensional standard; verify the housing, ring and actual fluid before selection.
What is the size difference between #1 and #2 filter bags?
In the JINLV catalog, #1 is Ø180 × 450 mm (approximately 7.09 × 17.72 in) and #2 is Ø180 × 810 mm (approximately 7.09 × 31.89 in). Both share the catalog body diameter; #2 is longer. The bag number alone does not establish ring geometry, sealing-seat fit or installation tolerances. Verify a sample or drawing when replacing another brand.

Common industrial filter bag sizes
Swipe the table horizontally to see all specifications.
| Bag no. | Metric size | Imperial size | Reference flow | Filtration area |
|---|---|---|---|---|
| #1 | Ø180 × 450 mm | ≈7.09 × 17.72 in | 20 m³/h | 0.24 m² |
| #2Common | Ø180 × 810 mm | ≈7.09 × 31.89 in | 40 m³/h | 0.48 m² |
| #3 | Ø108 × 230 mm | ≈4.25 × 9.06 in | 6 m³/h | 0.09 m² |
| #4 | Ø108 × 380 mm | ≈4.25 × 14.96 in | 12 m³/h | 0.16 m² |
| #5 | Ø152 × 520 mm | ≈5.98 × 20.47 in | 12 m³/h | 0.18 m² |
- • Metric dimensions are the catalog reference. Inch values are rounded conversions at 25.4 mm/in, not a guarantee of fit with another brand's bag number.
- • Flow values are catalog references. The supplied source does not include full test conditions; these are not verified 1 cP water curves or guaranteed process capacities.
- • Viscosity, solids loading, retention rating and area affect actual flow and differential pressure.
- • Verify basket, ring, bottom construction and installed length before ordering.
- • The catalog maximum differential-pressure reference is 2.5 bar, not a housing design pressure or approval for every custom construction. Respect the lowest applicable bag, housing and process limit.

Existing housing: how to verify bag size and fit
- Have qualified personnel isolate, depressurize and drain the housing under site safety procedures before measuring. Never open an operating housing.
- Record bag-body diameter and length, stating whether the ring is included. Photograph the ring profile, sealing seat, bottom and support basket. Compare drawings using the same measurement datums.
- Check usable basket diameter and depth, ring outside diameter, sealing arrangement and hold-down method. A shared bag number does not establish the same ring geometry or dimensional tolerances.
- After dimensional matching, confirm fluid, temperature, rating definition, ring material, seam and acceptance requirements. Approve a new replacement construction against a drawing or sample.
#2 bag review example — not a customer case
The JINLV #2 catalog entry is Ø180 × 810 mm, 0.48 m², with a 40 m³/h reference flow. These values identify a candidate size; they do not guarantee 40 m³/h with a viscous process liquid. Provide the ring drawing, fluid viscosity, solids loading and allowable pressure drop. Agree manufacturing tolerances on the order drawing.
From specification to purchase
What if your filter bag does not match this size chart?
Use the chart to identify a candidate, not to force an old bag into the nearest number. Choose the next step from the mismatch you actually measured.
01Different inch label
Compare actual dimensions and measurement datums. Rounded metric conversions are not evidence that another supplier's nominal size is interchangeable.
02Body fits, ring does not
Send the ring profile, sealing-seat and hold-down details. Body diameter and length alone are not enough to approve the sealing arrangement.
03Non-standard dimensions
Request a custom-size review using a drawing or sample. Include the basket dimensions and process duty; do not infer a standard #6 or #7 specification from this #1–#5 table.
The checklist opens in an editable inquiry form. Add your drawing or old-part photos there; no request is sent until you submit it.
Size-chart source and flow limitations
Reference basis
Sizes #1–#5 reproduce JINLV catalog references. The downloadable PDF is a derived size/RFQ reference, not the complete product catalog or a universal bag-size standard.
What is not established
The complete flow-test conditions are not available in the supplied source. Do not treat these numbers as a verified clean-water rating, a per-bag sizing guarantee or a basis for simply multiplying capacity.
Before approval
Measure the sealing ring, usable basket diameter and installed length. Supply viscosity, solids loading, temperature and allowed pressure drop before selecting a bag count or housing.
