Simple to operate:
The air ejector has no moving parts and no lubrication is necessary. After applying leak detection fluid along seam, simply place the vacuum device over the area to be tested and open the air valve.
Rugged yet light weight:
Our shockproof Vacuum Devices are built with lightweight acrylic which can be heat formed for special applications. The tough rubber gasket is designed to provide a maximum seal.

Fast, safe evacuation:
Air ejection on standard models is less than 30 seconds. Our ejector is explosion proof. Uses no electricity. Your compressed air supply (60-120 psi) will insure safe, economical operation.
