KOSA Filtration · Sanitary Cartridge Housings
316L Multi-Round Cartridge Filter Housing
A hygienic 316L stainless steel multi-cartridge vessel that scales flow and dirt-holding capacity for main-line clarification, CIP supply and high-purity water duty.
Key Takeaways
- 316L multi-round body scales flow with multiple cartridge elements.
- Pairs with single-cartridge vessels for point-of-use polishing.
- Bag vessel upstream extends cartridge life on coarse streams.
- Hygienic surface and 316L corrosion resistance for cleanable service.
316L multi-round cartridge housing
The KOSA 316L stainless steel multi-round cartridge filter housing accepts multiple standard sanitary cartridge elements in a single polished vessel, scaling dirt-holding capacity and flow for upstream clarification, CIP supply and high-purity water duty.
316L Single Cartridge Vessel 1 NPT
Compact single-cartridge sanitary housing for point-of-use.
316L Single Cartridge Vessel 3/4 NPT
Small-footprint sanitary cartridge housing.
316L Bag Filter Vessel
Sanitary bag vessel for coarse pre-filtration.
Multi-round vs single-cartridge
| Factor | Multi-round (this housing) | Single-cartridge vessel |
|---|---|---|
| Flow / dirt-holding | High — many elements in one body | Low — one element, easy swap |
| Footprint | Larger body, centralised | Small, distributed skid points |
| Changeout | Batch swap of multiple cartridges | Quick single-element change |
| Typical use | Main-line clarification, high-purity loops | Point-of-use, small lines, sampling |
Selection depends on flow, available pressure drop budget and how cartridge changeout is scheduled on your line. Always confirm dimensions and connection style against your existing piping.
Where it fits
This housing is a common anchor for food, beverage, pharmaceutical-support and high-purity water streams where a hygienic 316L body and cleanable surface finish are required. Pair it with single-cartridge vessels for point-of-use polishing and with bag vessels for coarse pre-filtration.
Which vessel should you pair it with?
1. Is this the main-line clarification step?
Yes → multi-round housing carries the bulk flow; add a bag vessel upstream for coarse protection.
2. Do you need point-of-use polishing?
Yes → a single-cartridge vessel (1 NPT or 3/4 NPT) handles small, distributed points.
3. Is the stream coarse and high-volume?
Yes → a bag filter vessel removes bulk solids before the cartridge stage to extend cartridge life.
