Performance & Sizing
Equilibar Vacuum Regulator
Incredibly stable vacuum control across varying flow rates!
The Equilibar precision vacuum regulator offers nearly flat-line vacuum pressure
control across three to four orders of flow magnitude. It is available in
sizes from 1/4" to 2.5" and larger.
Detailed performance curves are provided for the EVR-3 3/8" regulator, though
the same flat-line performance can be expected for other models when properly sized.
Stability across widely varying flow rates
Four orders of magnitude!
This chart shows flat line pressure stability across an incredible 4 orders
of flow rate magnitude. Competitive data, where available, is typically published
across a narrow range of flow.
Why is ultra low flow performance important? If your flow rate
falls below the minimum for the regulator, then excessive vacuum
Stability across varying Supply Pressure
This chart at right shows the excellent vacuum stability as the vacuum pump supply pressure varies widely.
Selecting the right size
This chart shows the projected vacuum performance at various regulator
body sizes. If you don't have a prefered piping size in mind, select the smallest
regulator that gives the precision that your application requires.
