Airgas Model N245A580 Brass High Purity Two Stage Pressure Regulator With 1/4" FNPT Connection And Non-Lubricated Check ValveThis series of two stage, high purity regulators is designed for non corrosive analytical and process applications requiring precise, stable, delivery pressure control. The two stage design yields a delivery pressure of less than 0. 02 100 psi inlet change. These regulators come with a CGA nipple that has a special high purity, non lubricated check valve incorporated into nose and prevents air and contaminants from entering the gas stream during

They are also equipped with a reverse-flow check valve to prevent backflow of gas into the regulator on the outlet

designed to regulate outlet flow

The optional bonnet vent adapter allows venting of hazardous gases in the event of diaphragm failure

These regulators also have a check valve cylinder connection that prevents contaminates from entering during cylinder changeover

along with the composite bonnets

6-gallon capacity

allows the exterior surfaces to maintain a good appearance in outdoor environments

this regulator is perfect for non-corrosive

This creates consistencies in processes and extends column life in GC applications

andnon-corrosive gas mixtures for analytical instrumentation

this regulator body has minimal internal volume - there are no large cavities and pockets associated with forged-body regulators

isolating contents from fire sources and limiting oxygen so spontaneous combustion risk is virtually eliminated
