Equilibar® Precision Vacuum Regulators

Incredibly stable vacuum control across varying flow rates

Equilibar® offers a unique type of vacuum regulator with more than 5X the flow stability of traditional spring regulators. That means that your vacuum process can remain stable even through wide variations in flow rate and supply pressures.

  • Is installed between your vacuum pump and your process
  • Controls in range 0 - 30 inHg
  • Sizes available 1/4" through 3"
  • Available in corrosive resistant materials (see below)


Control Mode

Set-Point Method

Manually adjusted

Uses a convenient 20-turn knob to adjust vacuum set-point (as pictured to right)

Computer automation

Uses an electronic pressure regulator to provide the set-point.


Equilibar Vacuum Regulators are based on our unique back pressure regulator technology.


Dramatic Stability Improvement

The superior flow stability of the 1/2" Equilibar® over the a competitive 1/2" vacuum regulator. Note that the competitive regulator works by bleeding air into the vacuum system rather than directly modulating the applied vacuum, explaining the opposite curvature.




Using the Equilibar® Vacuum Regulator

Using our new precision vacuum regulator is a snap. Simply connect your vacuum pump or house vacuum utililty to the Outlet port. Connect the process that you want to control to the Inlet port. Adjust vacuum knob to achieve the desired vacuum level.



Selecting the right size

If you don't have a prefered piping size in mind, select the smallest regulator that gives the precision that your application requires.
