Alfa Laval Streamline In-Line Filters and Strainers

Streamline in-line filters and strainers promote product quality and sanitation while protecting processing equipment such as homogenizers, meters, spray nozzles, needle valves and pumps. They feature a free-flow design and stainless steel construction for optimum sanitation and corrosion resistance, compatibility with a variety of woven and non-woven filtering media, and fast, easy servicing.

If used as a filter, the Streamline can be fitted with any one of seven filtering media.

As a strainer, it can be furnished with a single screen for straining large particles, or back-up tube and over screen with small perforations for removing finer particles.
