622-02050000 - Miller Smith 620 Series High Purity Two-Stage Air Regulator, CGA 346

Industrial Durability with Laboratory Precision

For welders and fabricators requiring high-quality air regulation for plasma cutting, laser assist gas, or specialized pneumatic tools, the Miller Smith 622-02-05-00-00 Silverline Regulator delivers unmatched performance. While designed for high-purity applications, its rugged construction makes it perfectly at home in demanding industrial environments where consistency and reliability are the top priorities.

Consistent Flow for Critical Tasks

Fluctuating air pressure can ruin a plasma cut or disrupt sensitive pneumatic machinery. This two-stage regulator solves that problem by automatically compensating for changes in cylinder pressure. As your air tank empties, standard regulators often allow the outlet pressure to creep up, requiring constant manual adjustment. The Miller Smith 620 Series maintains your set pressure (up to 100 PSIG) from a full tank down to empty, ensuring your equipment operates at peak efficiency without interruption.

Built to Last

Miller Smith (formerly Smith Equipment) is legendary in the welding industry for building gear that lasts. This regulator features a body machined from solid brass bar stock—not forged or cast—providing superior strength. It is nickel-plated to resist corrosion and wear. The internal seat is protected by a 316 stainless steel filter, preventing dirt and scale from the cylinder from damaging the regulator's sealing surface, a common cause of regulator failure in industrial settings.

Safety and Versatility

Equipped with a CGA 346 connection, this regulator is designed specifically for industrial air cylinders. It features captured vents (1/16" FNPT) on the bonnet, allowing for the safe piping away of gases if a diaphragm failure were to occur—a critical safety feature in enclosed shops. Whether you are running a high-precision laser cutter or simply need the most reliable air supply available, the Miller Smith Silverline series is the professional's choice.
