The Taco 409 Automatic Air Vent

The high-capacity design and 150-psi system operating pressure rating make this heavy-duty, brass Air Vent ideal for placement throughout commercial systems. Its conical shape significantly increases the clearance between the water level and internal mechanisms, reducing the potential that dirt floating on top of the water can foul the venting operation. Also features a convenient outlet connection for a 3/4” ID flex tube waste connection.
