Armstrong VA-4UM - VA-4UM Vortex-Style Air Separator (Strainer Not Included), 574114-023

Maintain peak hydronic system efficiency by effectively removing entrained air with the Armstrong VA-4UM vortex air separator. Designed for reliable performance, this 574114-023 unit prevents common air-related issues such as pipe noise, premature corrosion, and inefficient heat transfer within commercial and residential heating loops.

The unit utilizes a specialized internal design to generate a vortex, or whirlpool, action. This physics-based separation forces heavier, air-free water toward the outer tank walls, while directing lighter, air-entrained fluid toward the lower-velocity center where air bubbles can be efficiently trapped and purged from the system.

Key System Performance Baselines:

• Vortex Action: Engineered to maximize air separation through controlled whirlpool velocity.
• System Protection: Reduces oxidation and cavitation damage to sensitive mechanical components.
• Quiet Operation: Eliminates air-induced piping noise and air-bound flow obstructions.

⚠️ Application Profile: Ideal for commercial hydronic heating systems, radiant floor arrays, and large-scale boiler loops where air management is critical for operational longevity.
