VORTEX AIR SEPARATOR FOR HYDRONIC HEATING SYSTEM

摘要

A vortex air separator (14) is provided for removing air bubbles entrained in water circulating through a hydronic heating system. The air separator (14) includes a separation element (26) having a surface which is adapted to reduce the velocity and change the direction of water passing over the surface with a minimal pressure drop. In a preferred embodiment, the element (26) includes a spirally wound screen (26). Preferably, the spiral forms two or more complete turns.
