Self-Contained Liquid Ring Vacuum Pump
The 3AL is an ideal alternative to rotary vane
vacuum pumps and older liquid ring technology. The 3AL arrives ready to
use and requires no external water or oil supply. It has a self-
contained internal water circuit, is oil and maintenance free, and is
insensitive to dust and water vapor. The only thing it discharges is
cool, clean air. 3AL pumps are manufactured by Airtech up to sizes with
capacities of 260 CFM and can achieve vacuum pressure of 28.5”Hg (35
torr). Optional air-jets can be utilized to achieve vacuum levels
better than 29.5”Hg (10 torr).
