Precious Metal Catalyst Trap Filter is used for catching palladium, platinum and rhodium catalyst fines after hydrogenation and coupling reactions so the precious metal is recovered instead of lost to the product or waste stream. ISO 4022 is the reference cited for it on drawings, datasheets and purchase orders.
What ISO 4022 Means for Precious Metal Catalyst Trap Filter
The dimensions in the table below are supplied to suit ISO 4022. Where the standard sets requirements for the finished appliance, device or system, compliance testing of that assembly stays with its manufacturer; we supply the metal mesh part to the drawing and can provide material certificates and dimensional reports with the shipment.
Equivalent Standards
ISO 4022 defines permeability testing of sintered permeable metal media.
Precious Metal Catalyst Trap Filter Dimensions
| Size | Outer diameter (mm) | Length (mm) | Micron rating (u00b5m) | Design pressure (bar) | Media |
|---|---|---|---|---|---|
| Lab 25 | 25 | 100 | 1 | 16 | Sintered SS316L powder |
| Pilot 60 | 60 | 250 | 2 | 25 | Sintered SS316L powder |
| Plant 60 u00d7 1000 | 60 | 1000 | 5 | 25 | Sintered 5-layer SS316L mesh |
Specifying Precious Metal Catalyst Trap Filter Beyond the Standard
- Micron rating: 1–5 µm sintered media retains typical Pd/C fines.
- Pressure & temperature: Match the reactor discharge conditions and the back-flush pressure.
- Construction: All-welded SS316L with ASME BPE finishes where GMP cleaning is required.
When Precious Metal Catalyst Trap Filter Is Not the Right Choice
Not designed for bulk solids separation or for low-value catalysts where disposable bag filters are cheaper.
