Fully pneumatic device maintains set vacuum level
Piab’s piSAVE optimize is a vacuum-controlled proportional pressure regulator that uses a simple connection for air-driven pumps/ejectors.
The fully pneumatic device replaces the need to adjust the feed pressure; with the piSAVE optimize the desired vacuum level can be adjusted instead. piSAVE optimize 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 (optimized).
piSAVE optimize 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.
Available in two versions, as a stand-alone unit with a simple connection for any air-driven vacuum pump, and as a click-on version to Piab’s piCLASSIC & Classic lines of vacuum pumps, the desired vacuum level is easily set by an adjustment knob on the unit.
