SaniFlow STE-X, 304 multi-element filter housing by Exova

Description

The SaniFlow STE-X is an AISI 304 stainless steel sanitary filter housing that holds multiple cartridges, for high-volume operations in food and beverage plants. The standard code covers 3, 6, 9, 12, 16, 22, 24 or 36 cartridges from 10″ to 40″, and it can be customized for a larger number.

It accepts 2 1/2″ cartridges with a 226 or 222 double O-ring, with fin or flat end, as well as industrial double open end (DOE) cartridges. The crevice-free construction, with the interior polished to Ra ≤ 0.8 µm, reduces residue buildup, drains completely and supports in-line cleaning and sterilization (CIP and SIP).

It operates up to 10 bar and between −10 °C and 150 °C, depending on the gasket. It offers thirteen process connections—1 1/2″ to 3″ clamp, DIN 11851, Danish, 4″ flange and Fafeur—and every housing is hydrostatically tested.
