Designed to provide an enhanced level of air removal in hydronic heating, cooling or combination systems. Air is quickly and efficiently separated and vented through a factory-installed Taco 3/4" Hy-Vent®. The Hy-Vent along with Taco's innovative tangential flow pattern and primary separation chamber make the Vortech the most effective and reliable air separator you can buy. It requires no minimum run of piping and the convenient 1/2" bottom tapping makes it easy to install an expansion tank. Maximum operating pressure of 150 PSI (1034 kPa) and maximum operating temperature of 240 °F (115 °C).
