Sanitary Stainless Steel Strainers | GuardMax® Series

GuardMax® sanitary strainers are critical components in hygienic process lines, designed to protect sensitive equipment from coarse particles, fibers, metal debris, and process contaminants. Their fully drainable, hygienic design makes them ideal for CIP/SIP-compatible systems in food, dairy, pharmaceutical, and biotech applications.

Sanitary Filter Strainer  

Reliable Protection for Critical Equipment

Even small solid particles can cause severe damage to pumps, homogenizers, heat exchangers, and filling systems. GuardMax® strainers remove coarse contaminants before they reach critical downstream equipment.
