Pressure Regulators
Do I need one?

US Nitrogen Standards
Our instruments have been designed and engineered to connect directly to a US Standard Nitrogen Cylinder.  This cylinder is normally delivered with 2500 PSI / 173 Bar pressure or less.  The  instrument can be connected directly to this pressure source without any Pressure Regulation device.

Nitrogen Cylinders Outside USA
For instruments being purchased for use outside of the United States, you should consult your local gas supply (nitrogen) store.  Check the local requirements for the use and standards of high pressure gas.  A regulator will be needed if the tank pressure is greater than 173 Bar/ 2500 PSI. 

Our instruments come with a 6-Foot Filling Hose fitted with a CGA-580 Nitrogen connection (standard for USA) at the end of the hose.  Every country has different requirements and possibly different fittings.  You may need to buy an adaptor or change the nitrogen fitting for service in your area.  We might carry your local fitting in stock.  Please contact us directly to check if we carry your nitrogen fitting.

We supply two types of regulators.  The first is a High Pressure Regulator with a Supply Pressure of 200 Bar and Delivery Pressure of 0-100 Bar.  This type of regulator is designed to be connected directly to your local gas tank (pressure no higher than 200 Bar) and then connected directly to the instrument.  The regulator allows you to adjust the pressure to the operating pressure of the Pressure Chamber.  We will install a quick-connect and 6- Foot Hose to connect to the instrument direct.  The regulator looks similar to this:

The second type of High Pressure Regulator we carry has a Supply Pressure of 200 Bar and Delivery Pressure of 0-173 Bar.  This type of regulator is designed to connect to your local tank and trans-fill into one of our Portable Tanks or the internal tank of the Model 615 or Model 610.  This regulator is only used during the trans-filling of the tank.
