Since the pump handles 77 #/hr air at its (unchanged) suction pressure, the AAE will use 68.5 #/hr of atmospheric motive air and draw the new system suction of of 8.5 #/hr. air.
The new system suction flow is therefore 143 ACFM (10 torr suction).
Simplicity of design, operation and maintenance – no moving parts.
Availability in a wide range of materials. Standard material is cast iron with a stainless steel nozzle, but plastics , stainless steel and high alloy steel are all easily manufactured.
The Atmospheric Air Ejector is the most economical vacuum- producing device available.
