Airgas Model N145DHF580 Brass Specialty High Purity High Flow Pressure Regulator With 1/2" FNPT ConnectionThis series of regulators is used for applications requiring high gas flow rates and a compact design. These regulators can handle flows up to 250 liters per minute of nitrogen with only a 5 psig pressure drop. In addition, these units will handle hydrogen flow up to 1,000 liters per minute without the resonance problems associated with other regulators in this same application.

Optional 15 Ra electropolished with faceseal

easy reading

The metal-to-metal diaphragm seal prevents contamination by eliminating the need for a soft seal and provides a leak-rate design of less than 2 x 10-8 ccs helium

research sampling systems

A preset safety relief valve makes these regulators suitable for use only with non-corrosive gases

Two 10 x 32 UNF-threaded holes in the body allow for bracket or external panel mounting

NOTE: Choose a brass model for nonanalytical/non-corrosive service
