What does the 316L bag filter vessel do?

It is a sanitary 316L body that holds standard filter bags for coarse liquid clarification and for protecting downstream cartridge filters, used across food, beverage, cosmetic and general hygienic duty.

Which bag vessel closure should I choose?

V-clamp or other quick-open covers shorten changeout on lines that swap bags often; a standard bolted cover suits stable, longer runs. Match bag size and surface finish to your flow and hygiene need.

Is this referenced in KOSA application notes?

Yes — KOSA's cosmetic and food application bulletins discuss bag vessel and filter-bag selection for hygienic liquid lines, which is a useful starting point before a site-specific specification.

Bag vessel variants

Style	Clarification character
Standard bag vessel (this unit)	Versatile single/multi-bag body for general hygienic liquid filtration.
V-clamp quick-open multi-bag	Fast cover opening to shorten bag-change downtime on frequent-service lines.
FZ top-entry bag housing	Top-entry geometry for straightforward bag insertion and sealing.
Vertical open multi-bag	Vertical orientation with side access for multi-bag capacity in a compact footprint.

Bag size (#1/#2), closure type and surface finish should be matched to flow, changeout frequency and the hygiene requirement of your application.

Where it fits

Bag vessels are typically placed upstream of cartridge housings to remove bulk solids and extend cartridge life, or as the primary clarifier on moderate-duty hygienic lines. They are referenced in KOSA's cosmetic and food application notes for vessel selection.

Which bag vessel style do you need?

1. Do you change bags frequently?

Yes → a V-clamp quick-open multi-bag vessel cuts changeout time.

2. Do you need top-entry bag geometry?

Yes → the FZ top-entry housing gives simple bag insertion and sealing.

3. Is space tight but flow high?

Yes → a vertical open multi-bag housing packs capacity into a small footprint.
