A plating bath is an expensive thing to dump. Continuous bag filtration keeps particulate out of the deposit — roughness, pitting, and burrs in the finish trace back to solids in the bath more often than anything else — and extends the life of the chemistry you paid for.
What We Recommend
| Application | Media | Typical starting point |
|---|---|---|
| Nickel, copper, zinc baths — continuous turnover | Polypropylene felt | 1–10 µm |
| Decorative / bright finishes | Polypropylene felt or high-efficiency multi-layer | 1–5 µm |
| Cleaner & pretreatment tanks | Felt | 25–50 µm |
| Rinse water reclaim | Felt; Oil Magnet® if oil carryover from forming | 10–25 µm |
| Anodizing & chromating | Polypropylene felt (acid service) | 5–25 µm |
Practical Notes
- Polypropylene is the default — it handles the acid and alkaline chemistry of most plating lines. Hardware matters too: specify plastic or stainless rings to match the bath.
- Turnover rate beats micron rating. A bath turning over 2–3 times per hour through a 10 µm bag stays cleaner than one turning over once per hour through a 1 µm bag. Size the system for flow first — see the sizing guide.
- Tight ratings load fast. At 1–5 µm, keep spare bags on the shelf and consider size 2 for change-out interval.
