An accurate filter bag quotation depends on clear dimensions, material, construction, quantity, application, and operating conditions. Buyers should send bag diameter or flat width, length, top and bottom style, dust or liquid type, temperature, quantity, delivery country, and photos, drawings, or samples when available.

Dust Collector Filter Bag RFQ Table
| RFQ Field | What To Send | Why It Matters |
|---|
| Dust collector type | Pulse jet, reverse air, shaker, or other system type | Cleaning method affects bag construction and fit. |
| Bag size | Diameter and length, or flat width and length | Correct dimensions prevent poor sealing or installation failure. |
| Top style | Snap band, ring, cuff, flange, hanger, loop, or grommet | Top design controls sealing and installation. |
| Bottom style | Disc, reinforced, open, or custom bottom | Bottom construction must match the cage and equipment. |
| Material | Polyester, acrylic, aramid, PPS, PTFE, fiberglass, P84, or current media | Material depends on temperature, chemistry, and dust conditions. |
| Finish | Membrane, anti-static, water/oil repellent, singed, glazed, or other finish | Surface treatment depends on dust and operating conditions. |
| Operating data | Temperature, moisture, chemical exposure, dust type, cleaning pressure | Application data helps avoid unsuitable media selection. |
| Quantity and delivery | Quantity, delivery country, target delivery date | Needed for quotation, packing, and shipping review. |
Liquid Filter Bag RFQ Table
| RFQ Field | What To Send | Why It Matters |
|---|
| Bag size | Standard size, diameter and length, or housing model | The bag must fit the housing basket and sealing area. |
| Micron rating | Required micron rating or current bag rating | Micron rating affects filtration result and pressure drop. |
| Material | PP, PE, nylon, PTFE, or current media | Material must match fluid chemistry and temperature. |
| Ring or top | Plastic ring, steel ring, sewn ring, or other top | Top design affects sealing and housing compatibility. |
| Liquid details | Liquid type, viscosity, temperature, solids, flow rate if known | Application details help confirm filtration suitability. |
| Quantity and delivery | Quantity, delivery country, target delivery date | Needed for quote and logistics review. |
Filter Cage RFQ Fields When Cage Matching Is Needed
For dust collector projects, include cage diameter, cage length, wire count, ring spacing, top style, bottom style, venturi requirement, and tube sheet hole information. Photos of the cage top, bottom, venturi, and tube sheet help confirm fit.
Custom and Replacement Filter Bag RFQ Fields
For replacement projects without drawings, send the old bag photos, flat width, total length, top and bottom close-ups, cage photos, equipment model, and any nameplate information. For custom bags, add expected material, finish, seam, thread, ring, label, packing, and documentation requirements if applicable.
Photos, Drawings, and Samples
Clear photos reduce quotation errors. Send a full bag photo, top construction photo, bottom construction photo, flat width or diameter photo, length photo, cage photo if used, and equipment nameplate if available. If the old bag is damaged, photograph both the damage and any intact sealing areas.
Common Quotation Mistakes To Avoid
- Sending only a product name without dimensions.
- Mixing diameter and flat width without labeling the value.
- Forgetting top and bottom construction photos.
- Requesting material only by color instead of media type or application.
- Missing temperature, dust or liquid type, quantity, and delivery country.
- Sending unclear photos without a measuring tape or reference point.

Filter Bag RFQ FAQ
What information is most important for a replacement filter bag quote?
Diameter or flat width, length, top style, bottom style, material, operating conditions, quantity, delivery country, and photos are the most important fields.
What if I do not know the filter bag material?
Send the application, temperature, dust or liquid type, current bag photos, and any nameplate or old order information. The material can be reviewed before quotation.
Can I request a quote without drawings?
Yes. Photos, measurements, old samples, and equipment information can often support a replacement review.
Should I send diameter or flat width?
Send both if possible. If diameter is unknown, lay the bag flat, measure flat width, and label it clearly.
What photos should I send?
Send full bag, top, bottom, length, flat width or diameter, cage, tube sheet, equipment nameplate, and any damaged areas.
Can SFFILTECH review filter cage information with the bag quote?
Yes. Send cage diameter, length, wire count, ring spacing, top, bottom, venturi, and tube sheet details when cage matching is needed.
Why is delivery country requested?
Delivery country helps review packing, shipping method, documentation, and quotation conditions.
