The Taco 4900 Series 3" Flanged Carbon Steel In-Line Air & Dirt Separator (MPN: 4903AD-125) delivers dual-action system protection to clean and optimize large-scale closed-loop hydronic heating, chilled water, and cooling tower loops.

Dual-Action Protection Matrix:

  • Simultaneous Air & Sludge Removal: Micro-bubbles seamlessly adhere to the internal stainless steel PALL rings to safely exit through the top auto-vent mechanism, while heavy sand, dirt, and magnetite particles down to the smallest micro-clogs drop completely out of suspension into the bottom sump.
  • ASME Section VIII Construction: Built and certified precisely to demanding ASME compliance codes, ensuring optimal long-term lifecycle performance inside rigorous municipal, federal, and institutional mechanical plants.
  • System Efficiency Retention: Proactively eliminates system noises, localized rust build-up, pump-impeller erosion, and heat exchanger fouling to prevent loss of overall thermal efficiency and high energy billing waste.

System Parameters:

  • Media Compatibility: Suitable for closed water or water/glycol fluid loops with up to a 50% max volumetric concentration.
  • Sump Integration: Engineered with a bottom drain port to allow quick, safe blowdown flushing of captured system sludge without tearing down or breaking into lines.
