More About this Item

The air saver circuitry is perfect for any lab or process application. Powered by compressed air only; the pneumatic vacuum switch is the brain behind the system that constantly monitors and controls the vacuum level. Eliminates the constant air loss and noise of most venturi vacuum pumps. Since it uses no electricity it is inherently intrinsically safe. The vacuum switch is adjustable from 0 to 30” Hg with a hysteresis of 3”Hg.
