A Filter Core is the central filtration component in liquid, gas, or hydraulic systems, designed to remove contaminants (particulates, debris, or impurities) while maintaining optimal flow rates. It serves as a replaceable or cleanable element within filter housings, ensuring system cleanliness and equipment protection.

✔ Food & Beverage – Sanitary process filtration
Micron Rating – Match to target contaminant size (e.g., 10µm for hydraulic systems)
Media Material – Choose chemically compatible media (e.g., PTFE for acids)
Flow Requirements – Size core to avoid >10% pressure drop at max flow
Environment – Stainless steel for corrosive settings; plastic for lightweight needs
Pressure Gauge – ΔP > 15 PSI signals clogging
Visual Inspection – Discoloration/deformation requires replacement
Service Life – Typical 3–12 months (varies by contaminant load)
Custom Designs – Odd sizes or special materials (e.g., nickel alloy)
Validation Testing – Bubble point, multi-pass efficiency reports
Rapid Delivery – 80% of SKUs in stock for urgent needs
