The Uniweld UNF3 is a nitrogen flow indicator designed for monitoring nitrogen gas flow in HVAC applications. This tool confirms the flow through copper lines during the brazing process, ensuring that oxygen is displaced and preventing oxidation. The float ball within the indicator rises if nitrogen flows properly, providing a visual confirmation of operational integrity.
This nitrogen flow indicator effectively manages the nitrogen purging process, minimizing contamination risks and enhancing system performance.
