Taco Commercially Rated Brass Air Vent, 3/4" NPT 150 PSI

Taco 409-3 Commercially Rated Brass Air Vent.
The Taco 409 air vent is a heavy duty brass vent rated to 150 PSI system operating pressure. The conical shape
of the vent significantly increases the clearance between the water level and internal mechanisms, reducing the
potential that dirt floating on the top of the water could foul the venting operation. It features a convenient
outlet connection for a 3/4” ID flex tube waste connection. It’s high capacity design makes it ideal for placement
throughout commercial systems.

The Taco 409 is intended for installations filled with 100% water or approved glycol solutions (do not exceed 50% glycol) for hydronic heating systems
