Price on application

Housings are quoted to duty — vessel size, material, seal compound, internal finish, connections and any certification requirement all move the price. Give us the fluid and the flow and you get a firm number, plus the expected bag change interval so you can budget the consumable too. Request a quote →

Tell us the duty, not the part number

Flow rate, fluid, temperature, particle size and how often you want to change bags. We size the housing and the bag around that and quote the pair, delivered and commissioned.
