This is designed with the Iso-Valve, which isolates pump from system, making it easy to measure rate of rise. Also its offset rotary vanes work in conjunction with vacuum pump oil to create a powerful compression inside the pumping chamber. Its gas ballast feature helps keep oil clean for longer time by introducing a small amount of dry atmospheric air to prevent condensation of moisture within the pumping chamber.
