Sanitary Stainless Steel Strainers | GuardMax®

PST Series

Vital Protection for Process Lines and Sensitive Equipment

GuardMax® sanitary strainers are critical components in hygienic process lines, designed to protect sensitive equipment from coarse particles, fibers, metal debris, and process contaminants. With a fully drainable, hygienic design, they are entirely compatible with CIP/SIP systems and allow the use of various filtration elements in food, dairy, pharmaceutical, and biotech applications.

The Importance of Sanitary Strainers and Material Standards

Even small solid particles, pipe rust, or metal flakes can cause severe damage to expensive equipment such as pumps, homogenizers, heat exchangers, and filling systems. Selecting the right strainer drastically reduces unwanted line downtime.

All product-contact parts in the GuardMax® series are manufactured from premium 316L stainless steel, offering exceptional corrosion resistance in acidic and alkaline environments. Furthermore, sealing gaskets and elastomers are FDA-approved, ensuring the highest level of safety for food and pharmaceutical industries.

Y-Type Sanitary Strainer

Y-Type Design & Quick Service

Economical, Compact, and Reliable Protection

GuardMax® strainers remove coarse contaminants before they reach critical downstream equipment. The Y-Type models, with their compact design, can be installed both horizontally and vertically, allowing for rapid servicing and element replacement.

  • Horizontal or vertical installation with minimal space requirements
  • Quick servicing and easy access to the filtration element
  • Removal of coarse particles prior to entering pumps
  • Significant reduction in downstream equipment wear

PST-S Inline & PST-A Angle Models

Ultra-Low Pressure Drop & High Viscosity Handling

The PST-S (Inline) straight-through design (0° inlet/outlet) offers the lowest pressure drop in the GuardMax® family, making it ideal for continuous processing lines and CIP circuits. Conversely, Angle (L-Type) models are engineered for higher capacities and viscous fluids.

  • Angle Type: Ideal for viscous fluids with extremely easy basket removal
  • Inline Type: Coaxial inlet/outlet providing minimal pressure drop
  • Complete drainability across all models for hygienic safety
  • High durability for elevated flow rates and central pipelines
