Model 720 Automatic Air Eliminator
The 720 Air Eliminator has been designed to eliminate air as fast as it can be separated. Use on any hydronic or water service system where pressure does not exceed 150 PSIG and the temperature is no greater than 250 degrees Fahrenheit. Its design lends to maintenance free operation due to the self-cleaning mechanism. The 720 Air Eliminator will not open if negative pressure occurs so air cannot be drawn back into the system should a vacuum situation occur.
