piSAVE optimize is a vacuum-controlled proportional pressure regulator. A fully-pneumatic device, the unit is easy to use and install. It is ideal for air-driven pumps and ejectors and is designed especially to simply connect for any air-driven pump. The unit senses the vacuum level in the system. The feed pressure of the compressed air to the vacuum pump/ejector is automatically regulated and controlled to maintain the set vacuum level. The vacuum level is kept constant in this manner and the air/energy usage is kept to a minimum for the application. The system provides maximum feed pressure/vacuum flow to the vacuum pump until the vacuum level starts to build up. This means no reduction on the initial amount of flow or pick up speed in handling applications. The unit reacts quickly to changes in compressed air pressure or to changes in the degree of leakage into the vacuum system in order to maintain the set vacuum level.
