Oil Free Vacuum Pumps

Products > 3AL Series Vacuum Pumps 

 

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).
