Project evidence shows general fields for contact information, product type, dimensions, quantity and timing, dust, temperature, media or exposure notes, part-number evidence, and RFQ details. Family-specific fields in this guide are preparation guidance, not a promise that every item has its own online control. The saved 2026 form configuration contains a file field, but direct inspection of the current public control was blocked during this audit. This guide therefore does not claim upload capability. Use the request page's separately visible email or WhatsApp paths for photos, drawings, and RFQ files, and place a concise index in the RFQ Details field.

Give the inquiry a project reference, contact and company, destination country or region, collector maker/model/serial/location when known, component family, installed position, every part number and its source, requested quantity, unit system, and reason for replacement. Manufacturer literature distinguishes fabric bags, cartridges, and rigid pleated baghouse elements, so select the family from observed construction rather than a casual site nickname. [1] Tag each value M for measured, C for copied, O for observed, A for assumption requiring verification, or U for unknown.

For a fabric bag, record overall length, body diameter or flat width, measurement method, top attachment, bottom construction, seam, bands, rings, loops, cuffs, reinforcement, and installed orientation. When a cage or tubesheet controls the fit, include the cage size and ends plus the tubesheet opening or other mating evidence. One LP baghouse manual shows a snap-band collar seated at a tubesheet before its cage is lowered into the bag; that equipment-specific example explains why collar, tubesheet, and cage should be documented together. [3] It is not a universal installation method.

Record outer shape and dimensions, overall length, inner opening, both end caps, each open or closed end, gasket location and profile, flange, hooks, studs, center hardware, liner, support features, and installed direction. A Downflo Oval manual identifies the gasket end, sealing surface, yoke, and access cover as a related assembly for that collector. [4] A separate cartridge data sheet uses outer/inner diameter, length, pitch diameter, gasket, end caps, media pack, straps, and liner as field categories. [5] Copy none of its values unless they belong to the actual item.

For a cage, record outside diameter, overall length, longitudinal wire count, ring count or spacing, top style, bottom style, one-piece or jointed construction, joint details, and material or finish only when documented. Photograph bends, corrosion, rough welds, broken wires, worn rings, and the relationship to the bag. If a venturi is present, record its opening, height or overall dimensions, flange or seating geometry, attachment method, installed orientation, and whether it is integral or separate. Do not infer that another venturi is interchangeable because its silhouette looks similar.

Name the accessory by its observed function and installed location: gasket, clamp, cap, nozzle, diaphragm, valve part, fastener, seal, or another component. Record overall dimensions, hole pattern, thread, flange, connector, clamp range, mating part, orientation, markings, quantity, and condition. If material or finish is unknown, describe appearance without assigning a grade. A photo of the accessory alone is incomplete; include the mounting position and the adjacent feature it must connect to.

State the dust or fume and source process, collector arrangement, cleaning method, normal and documented peak/startup/shutdown/upset temperature information, moisture or condensation, oil or sticky material, known chemistry, abrasion, sparks or hot-particle history, airflow or process changes, current media when supported, and observed failure. EPA guidance identifies particle characteristics, cleaning mechanism, temperature, moisture, and corrosives as relevant fabric-filter considerations. [2] This checklist gathers those inputs; it does not convert them into a material recommendation or safe operating range.

Separate quantity by line item and collector position. Say whether the request is a full changeout, partial set, spare stock, trial quantity, or repeat order, without implying that any order model is available. Specify protection, cartons, pallets, separators, moisture barriers, item labels, carton marks, lot separation, inspection records, or other documents only when the project requires them. State destination and shipping constraints. Give a required-by date, outage window, or desired review date together with flexibility; treat it as buyer planning information, never as a promised lead time.

Photograph the full component from two sides, both ends, attachment and sealing details, tool placement, markings, installed orientation when safely available, mating parts, damage, and packaging evidence. Use a neutral file pattern such as PROJECT-COLLECTOR-COMPONENT-VIEW-01 and maintain an index that explains what each view proves. Do not put customer names or sensitive data in public filenames. Replacement indexes commonly use several fields together—part or OEM number, diameter, length, medium, and end cap—which reinforces why one number or one photo is not enough. [6] The index still does not confirm fit.

Example RFQ (illustrative; no customer, order, price, lead time, or fit claim):
Project: SAMPLE-RFQ-01; destination region recorded; contact fields supplied in the form.
Component: fabric filter bag with separate cage; full-set versus partial-set status marked unknown pending collector count.
Records: label code copied as [C]; collector model unknown [U].
Bag: overall length and body diameter entered with units [M]; snap-band-style top [O]; closed reinforced bottom [O]; seam photographed; nominal tolerance unknown [U].
Cage/venturi: cage OD, length, wire count, and ring spacing [M]; top/bottom, joint, and condition [O]; venturi attachment photographed; material grade unknown [U].
Operating context: dust/process, cleaning method, normal and peak temperature records, moisture observation, and reason for replacement stated; current media copied from an old record but flagged for verification [C].
Commercial scope: requested quantity to be confirmed after compartment count; packaging labels requested by project reference; destination stated; required-by window is a buyer target, not a supplier commitment.
Files: SAMPLE-RFQ-01-BAG-OVERALL-01, -TOP-01, -BOTTOM-01, -SEAM-01, -CAGE-01, -VENTURI-01, and a drawing index sent through the listed email file path.
Open questions: confirm quantity, media record, tubesheet evidence, quotation deviations, exclusions, and the verification step required before ordering.
