Airgas Model N145DHF Brass Specialty High Purity High Flow Pressure Regulator With 1/2" FNPT Connection Regulator The Airgas® heavy-duty high-pressure cylinder

The Airgas® heavy-duty high-pressure cylinder regulator’s piston sensor design provides structural reliability in high-pressure applications

Captured bonnet ports with optional vent adapters are standard on both stages and allow the venting of hazardous gases in the event of diaphragm failure

Convoluted Hastelloy C-22 diaphragms provide excellent regulating characteristics and allow for internal vacuum purging

The low torque control knob and self-relieving feature permit easy adjustment of pressure in closed or dead-end systems

Airgas Model N145DHF Brass Specialty High Purity High Flow Pressure Regulator With 1/2" FNPT Connection Regulator The Airgas® heavy-duty high-pressure cylinderThis 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.
