Harris 301 Series CO2 Flowgauge Regulator 0-60 SCFH CGA 320

Harris 301-CD60-320 Single-Stage CO2 Flowgauge Regulator

The Harris Model 301-CD60-320 is a specialized single-stage flowgauge regulator engineered specifically for Carbon Dioxide (CO2) shielding gas applications. Designed to meet the rigorous demands of industrial environments, this regulator combines a compact footprint with heavy-duty construction materials. The unit features a solid brass body and a brass-painted zinc bonnet, materials selected for their corrosion resistance and mechanical strength. This model is capable of delivering accurate flow rates up to 60 Standard Cubic Feet per Hour (SCFH), making it highly suitable for MIG (GMAW) and Flux-Cored (FCAW) welding processes that utilize CO2.

Technically, the Model 301 distinguishes itself with Harris's proprietary one-piece encapsulated seat design. This assembly includes an internal filter that proactively protects the PTFE Teflon seat from particulate contamination, which is a leading cause of regulator failure and creep. The internal geometry is optimized to maintain stable flow characteristics even as cylinder pressure decays. Pressure regulation is managed by a durable Neoprene diaphragm, providing consistent response and sensitivity. The outlet connection is a standard 5/8" - 18 (F), and the inlet is machined to CGA 320 specifications, ensuring compatibility with standard CO2 cylinders.

The regulator is equipped with two 2-inch steel dual-scale gauges that provide clear readouts of cylinder pressure and delivery flow. The ergonomic brass "T" screw handle allows for precise and smooth adjustment of flow settings. Safety and compliance are paramount; this model is UL listed and manufactured in the USA, adhering to strict quality control standards. The manufacturer backs this product with a 7-year warranty, reflecting confidence in its long-term reliability and performance in professional settings.
