Air & Dirt Separator
The Caleffi Air & Dirt Separator is designed to remove air bubbles and dirt particles from hydronic heating and cooling systems, improving system efficiency and protecting critical components from damage. By reducing air pockets and sediment buildup, this separator helps maintain optimal flow and heat transfer, leading to reduced maintenance and increased equipment lifespan.

✔ High-Efficiency Air & Dirt Removal – Captures and eliminates air bubbles and particulates down to 5 microns.
✔ ASME & CRN Certified – Designed for high-performance commercial and industrial systems.
✔ ANSI Flanged Connections – Ensures easy installation and integration with existing piping.
✔ Self-Cleaning Function – Integrated purge valve for effortless maintenance.
✔ Reduces Corrosion & Pump Cavitation – Improves system longevity and prevents damage to critical components.
✔ Low Pressure Drop – Minimizes system resistance for optimal flow.
The NA546 Air & Dirt Separator uses a coalescing mesh to efficiently separate air and debris from hydronic systems. Air rises and is automatically vented, while dirt settles at the bottom and is easily flushed out through the drain valve—keeping your system clean and running at peak efficiency.
