3000187 - Harris 301 Series Inert Gas Regulator, CGA 580, 0-100 PSIG

Harris Model 301-100-580 Single-Stage Pressure Regulator

The Harris Model 301-100-580 is a specialized single-stage pressure regulator engineered for inert gas applications, specifically Nitrogen, Argon, and Helium. Designed with a focus on durability and precision, this unit features a solid brass body and a brass-painted zinc bonnet, ensuring longevity even in demanding industrial environments. The regulator is equipped with a CGA 580 inlet connection, making it compatible with standard inert gas cylinders, and delivers a consistent outlet pressure range of 0-100 PSIG.

Technically, the Model 301 stands out due to its one-piece encapsulated seat design. This assembly includes an internal filter that actively protects the PTFE Teflon® seat from particulate contamination, a common cause of regulator failure. The neoprene diaphragm provides responsive pressure control, allowing for accurate adjustments via the easy-to-operate brass "T" screw handle. The unit is fitted with two 2-inch steel dual-scale gauges, providing clear readings for both cylinder contents and delivery pressure. The outlet connection is a standard 9/16" - 18, suitable for most inert gas hose fittings.

This regulator is UL listed and manufactured in the USA, adhering to strict quality standards. It is particularly well-suited for light to medium-duty applications where portability is key, such as HVAC purging, pressure testing, and blanketing operations. The robust internal architecture ensures that despite its compact footprint, it maintains the reliability expected from Harris equipment.
