The Additel ADT780-1K-EPUMP air pressure source uses electric-driven pumps to generate positive pressure and vacuum pressure. It can generate - 13.5 psi (-0.095MPa, -0.95 bar) vacuum and 1,080 psi (7.5MPa, 75 bar) pressure. With two independent control and pressure generation systems, vacuum and pressure can run simultaneously. This system supplies a steady and reliable air source for Additel 780 pressure controller.
