OneStep Mode Switching Switch between functions instantly without adjustments or guesswork. Attach your standard 1/4inch refrigerant hose and nitrogen regulator, then turn the dial from OFF to PURGE to BRAZE in seconds. This eliminates the need for complex valve settings, ensuring fast setup and immediate readiness. Precision Flow Control Designed for a 50 PSI inlet (up to 200 PSI maximum), the internal flow channel provides a steady 25–35 SCFH nitrogen output for purging and 3–6 SCFH for brazing at 50 PSI. This precise regulation prevents waste, reduces nitrogen consumption, and lowers operating costs during HVAC or refrigeration system work. Effective Purge for Longer Equipment Life Quickly remove residual refrigerant, moisture, and debris from copper tubing. Prevent internal oxidation and corrosion, improve system cleanliness, and extend the operational lifespan of your equipment. This results in fewer breakdowns, reduced downtime, and minimal maintenance requirements. Durable AllMetal Construction Built from a composite of aluminum alloy and stainless steel for impact, wear, and aging resistance. Compact and lightweight at approximately 130 g, it fits easily into a tool kit or pocket for convenient transport and use. Engineered to withstand demanding job site conditions while maintaining reliable performance. Applications 1. HVAC system installation – Purge lines before charging or brazing to protect against contamination. 2. Refrigeration – Maintain clean copper tubing for efficient system performance and reduced service calls. 3. Onsite brazing – Achieve consistent nitrogen flow for quality brazed joints without oxidation. Compatibility Works with standard 1/4inch refrigerant hoses and nitrogen regulators, making it easy to integrate into existing tools and workflows. Designed for professionals who need speed, accuracy, and durability in nitrogen purging and brazing operations.
