ARMSTRONG 1AV Air Eliminator 1/2” PN16
Extends system life with automatic float-controlled air discharge.
The ARMSTRONG 1AV Air Eliminator removes accumulated free air automatically from pressurized water and liquid systems. In addition, its float mechanism minimizes liquid loss. Therefore, it prevents pump cavitation and corrosion while improving energy efficiency.
The ASTM A48 Class 30 cast iron body provides long service life under heavy-duty conditions. Moreover, it operates safely at a maximum working pressure of 21 bar and a temperature tolerance of 93°C. Furthermore, the 1/2″ (DN15) connection size allows easy integration into existing installations.
