A Filter Screen (or Strainer Screen) is a perforated or woven barrier designed to physically separate and remove solid particulate contaminants from liquids or gases as they flow through a system. It serves as a pre-filter to protect more sensitive downstream equipment like pumps, valves, and finer filters from damage, clogging, and wear caused by large debris.

The primary role of a filter screen is coarse filtration and protection. Its specific purposes include:

• Debris Removal: Capturing and retaining large particles such as dirt, scale, pipe slag, and welding beads
• Equipment Protection: Shielding critical components from abrasive damage and operational failure
• System Efficiency: Preventing premature clogging of finer downstream filters
• Process Quality: Ensuring the purity of process fluids in sensitive applications

1. Contaminated Inflow: The fluid enters the strainer body or housing
2. Screening: The fluid passes through the screen element which blocks particles larger than its micron rating
3. Clean Outflow: Filtered fluid exits the strainer and continues through the system
4. Contaminant Retention: Trapped debris accumulates for periodic removal

• Micron Rating / Mesh Size: Determines the largest particle that can pass through
• Material of Construction: Typically 304/316 Stainless Steel, Brass, or Plastic (PP, PVDF)
• Screen Type: Plain Dutch Weave, Twilled Dutch Weave, Square Mesh
• Dimensions: Outer Diameter (OD), Inner Diameter (ID), Length
• Flow Rate & Pressure Drop: Determined by the open area of the screen
• Pressure and Temperature Ratings: Must match system requirements

Filter screens are used across multiple industries:

• Water & Wastewater: Intake screens, well points, filter press feeds
• Oil & Gas: Pipeline strainers, upstream wellhead protection
• Chemical Processing: Filtering process fluids and raw materials
• Food & Beverage: Straining ingredients, protecting homogenizers
• Pharmaceutical: Pre-filtration of process water and solvents
• Power Generation: Cooling water intake, protecting turbine auxiliaries
• Manufacturing: Hydraulic and coolant system protection

• Precision Manufacturing: Consistent and reliable filtration performance
• Superior Materials: High-quality, corrosion-resistant materials for long service life
• Custom Solutions: Available in custom sizes, shapes, and micron ratings
• Expert Application Support: Technical assistance for optimal system performance
• Proven Durability: Built to be cleaned and reused repeatedly

To select the correct filter screen, please provide:

• Application (e.g., Pump Suction Strainer, Pipeline Protection)
• Housing Type/Model (e.g., 2" Basket Strainer, 1" Y-Strainer)
• Micron Rating/Mesh Size Required
• Fluid Media (e.g., Water, Oil, Chemical Solvent)
• Operating Pressure & Temperature
• Material Requirement (e.g., 316SS, Brass, Polypropylene)
• Dimensions (OD, ID, Length, and connection type if applicable)
