SaniFlow STE-DO, 316L industrial filter housing (DOE) by Exova

Description

The SaniFlow STE-DO is an AISI 316L stainless steel industrial filter housing for one double open end (DOE) cartridge. It is designed for process filtration in food and beverage and in the pharmaceutical industry, in installations where a positive seal between the dirty side and the clean side is not required.

All product-contact parts are 316L, bright polished inside and out: it is easy to clean and the unit can be inspected visually. It accepts 2 1/2″ DOE cartridges in 10″, 20″, 30″ and 40″, and operates up to 7 bar and 90 °C.

The bowl is released with a single clamp, and a central tie rod holds the cartridge in place during the operation, so the cartridge is changed without tools. It connects to the process with a 1 1/2″ clamp, a 1″ female BSP thread or a 2″ female BSP thread (with adapter), with or without legs.

Frequently asked questions

When is a housing for a DOE cartridge the right choice?

In process filtration where a positive seal between the dirty side and the clean side is not required: syrups, wines, liqueurs and beverages, prefiltration of process water, or pharmaceutical and cosmetic process fluids. If the process requires that seal, the right choice is a sanitary housing for double O-ring cartridges, such as the STE-01 or the STU-01.

How is the cartridge changed?

Without tools: open the clamp and release the bowl; the central tie rod keeps the cartridge in position during the operation.

What process connections does it have?

1 1/2″ clamp, 1″ female BSP thread or 2″ female BSP thread with adapter. They are selected in the ordering code (C, Q or L).

What are its maximum pressure and temperature?

Up to 7 bar (100 psi) working pressure and 90 °C (194 °F) maximum temperature.

Can it be integrated into a filtration skid?

Yes. We custom-design sanitary and industrial plug-and-play skids with housings, valves and instrumentation on a fixed or mobile frame: prefiltration and final filtration, parallel or duty/standby lines, bypass and recirculation, with clamp or threaded connections and ΔP measurement. Product contact is 316L and the frame is 304.
