Thrush Co. Manual #9636-1220 3.3 Suggested Equipment Although the standard Air Separator is a simple design, a Thrush Model 720 Air Eliminator is recommended to vent air from the system. 3.3.1 Model 720 Air Eliminator The Model 720 Air Eliminator is a unique high capacity, air elimination device. It is designed to eliminate air as fast as it can be separated from liquid. The valve will not open if negative pressure occurs, preventing air from being drawn back into the system.

The Model 720 Air Eliminator should be located in a clean, open area, where it is easily accessible for inspection, service and repair. 2.
