Product Introduction

The Clean Steam Filter is an inline hygienic housing for final particulate control in clean-steam services feeding sterilizers, SIP circuits, humidifiers and sensitive process users. Steam enters the compact upper head, passes through one cylindrical sintered 316L cartridge and leaves through the opposing sanitary outlet while retained scale, weld residue and pipe-borne debris remain within the metallic depth structure. A clamp-secured two-piece housing permits direct cartridge access, and dedicated top-vent and bottom-drain connections help remove trapped air and condensate during start-up, shutdown and maintenance. The assembly filters solid particles; it is not a moisture separator, steam trap, pressure regulator or steam generator.

Key Features

Electropolished 316L single-round filter housing

One cleanable sintered 316L stainless-steel cartridge

Choice of conservative 1, 5 or 25 µm cartridge grades

Hinged sanitary clamp for cartridge access

Opposing inline Tri-Clamp steam connections

Separate top vent and vertical low-point drain

Metallic filter medium suitable for repeated cleaning

Compact housing geometry with low internal hold-up

Customer Product Concerns

Clean steam can acquire particulate contamination from generation and distribution surfaces, but the final filter must avoid excessive pressure drop, retained condensate and maintenance ambiguity.

Pipe scale or fabrication debris can reach a critical steam userInstall a selected sintered stainless cartridge immediately upstream of the user to retain the specified particle fraction without introducing fibrous media.

An undersized element creates avoidable pressure loss at peak steam demandSize the housing and micron grade from actual steam mass flow, pressure and allowable clean differential pressure rather than connection size alone.

Condensate held in the bowl can wet the element and disturb start-up flowUse the centered low-point drain and top vent to establish a controlled warm-up and drainage sequence for the installed orientation.

Cartridge inspection is delayed by complicated vessel disassemblyRelease the single hinged sanitary clamp to lift the compact head and withdraw the one-piece metal cartridge for inspection, cleaning or replacement.
