Vent Gas Regulator | Simple in Form and Function

This Inert Gas Regulator is for delivering 0.5 to 1 PSIG to SNAP, Model 450 or VacStable vent port.

The regulator is used to step down the pressure in a Nitrogen or Argon bottle so it can be safely used as a gas source as an input into standard vacuum or mass flow controller valves.



  • Assembled and tested to work as a vent port for controllers and operate in safe limits
  • Paired with SNAP
    • Use a 3/8 I.D. hose to connect to the SNAP or 450 Vent ports
  • Paired with VacStable/Bleed Valve
    • Adapter kit needs to be ordered.

The purpose of this regulator is to take higher pressure tank gas (up to 3000 psi) and bring the pressure down to about 1 PSI.  This pressure is optimal for best performance of DigiVac vacuum control products.



This solution works nicely for mass flow, our VacStable valve, our SNAP controller, or our Concerto control manifold system.  If backfilling or bleeding in room air isn’t sufficient, our regulator can be used instead.  If a cleaner, dryer, or more specific gas is needed, this regulator can be a great solution.

It also is less complex than other regulators and will lead to less user error.  In a more complex regulator assembly, a user can accidentally turn the wrong knob or overpressure the device attached to the regulator, potentially causing harm to expensive valves and systems.


Reduce Your Worries with the Venting Gas Regulator


How to Use

Each one is individually assembled and tested:

  • Outlet pressure is set to 1 to 1.5 PSI and locked
  • A stripe of paint is set so you know where 1 PSI should be
  • Tested with actual vac stable valve
  • Include a quick start
  • Packaged and ship
