Specifications that inform the right choice
Compare the published grades, then confirm the supplied construction and project requirements in the technical submission.
| Format | Nominal dimensions | Selection and supply |
|---|---|---|
| Standard bag | 1 m × 1 m × 1 m | Choose fabric, inlet and handling configuration; confirm current stock and price. |
| Custom bag | To approved drawing | Confirm footprint, height, connections, support and fabrication programme. |
Technical notes and test basis
Dimensions describe the fabricated format. Working capacity depends on geometry, filling limits and the retained material. Confirm any lifting duty separately.
| FlowTex grade | Polymer | O90 (µm) | Normal permeability (mm/s) | Tensile MD/CD (kN/m) | CBR puncture (kN) |
|---|---|---|---|---|---|
| Mono 180 | PP | 180 | 50 | 40 / 40 | 6 |
| Mono 350 | PE | 350 | 300 | 44 / 35 | 4 |
| Mono 600 | PE | 600 | 350 | 41 / 35 | 3.5 |
Technical notes and test basis
Reference fabric averages. O90: EN ISO 12956; normal permeability: EN ISO 11058; tensile: EN ISO 10319; puncture: EN ISO 12236. Not finished-bag pressure, throughput or lifting ratings. O90 is not an absolute particle cut-off.
| FlowTex grade | Tensile MD/CD (kN/m) | O90 (µm) | Normal permeability (mm/s) | Mass (g/m²) |
|---|---|---|---|---|
| HF45 | 45 / 45 | 600 | 40 | 210 |
| HF60 | 60 / 60 | 600 | 27 | 280 |
| HF105 | 105 / 105 | 300 | 25 | 500 |
Technical notes and test basis
Nominal reference fabric values, subject to stated tolerances and the current project submission. Tensile: EN ISO 10319; O90: EN ISO 12956; normal permeability: EN ISO 11058; mass: EN ISO 9864. Fabric strength is not seam strength or allowable filling pressure.
From specification to site
Fabrication, QA/QC & African project supply
Start with the bag format
The standard 1 m × 1 m × 1 m format describes nominal fabricated dimensions. It is not a guaranteed usable cake capacity or lifting load. Ask for the current bag drawing, supplied configuration and stock allocation.
Compare the filter
Mono 180, suitable HF woven grades and nonwoven-lined composite constructions provide different filtration and structural combinations. Trial the proposed bag with the actual feed, including any conditioning.
Check stock and price together
Send the size, construction, quantity, location and required date. The quotation confirms current availability, price, port configuration and dispatch or fabrication programme. No live inventory or unverified “ships today” flag is shown.
Plan handling
State whether the bag stays on its pad to be emptied or needs a lifting-duty assembly. Handles or base-fabric strength alone do not establish a safe working load.
FAQ
Frequently asked questions
What standard dewatering bag size is available?
The standard format is nominally 1 m × 1 m × 1 m. Confirm the fabric, supplied dimensions, inlet configuration, quantity and current stock with the quotation.
What does a dewatering bag cost?
Price depends on fabric/liner construction, size, port and handling details, quantity and destination. Request an itemised stock or fabrication quotation rather than comparing dimensions alone.
Can I lift a full bag?
Only if the exact supplied assembly has a separately established lifting duty and handling instructions. Nominal volume, handles or fabric strength do not establish an allowable loaded mass.
Discuss your dewatering specification
Send the feed, volume, filtrate target, dimensions, location and programme. We will help define the next step.
