Pressure Step Deaerator (PSD)

A new and innovative tool that utilizes vacuum technology to deaerate entrained air in hot or chilled water hydronics systems. The compact design allows the PSD to be installed in almost any mechanical situation. The PSD is an efficient low-power consumption unit requiring only 110v and 3 amps to run, and is easy to program through simple LED readout controls.
