Western Enterprises VN Series HVAC Nitrogen Purging Regulator/Flowmeter - 25-35 SCFH Purge, 3-6 SCFH Braze, CGA-580

The Western Enterprises VN Series HVAC Nitrogen-Purging Regulator/Flowmeter combines regulator and flowmeter functionality in one compact unit for HVAC nitrogen purging and brazing applications. This hybrid design eliminates the need for separate components while providing preset flow rates for both purging and brazing operations.

Built with a heavy-duty brass body for demanding field conditions, this regulator features an easy-to-read nitrogen cylinder content gauge and dual flow rate capabilities. The CGA-580 connection ensures direct compatibility with standard nitrogen cylinders without requiring adapters.

Key Specifications

The preset flow rates eliminate guesswork during HVAC installations and repairs. The purge setting delivers high-volume flow for clearing lines and preventing oxidation, while the braze setting provides precise low-flow control for joint protection during soldering operations. The compact 5-1/2 inch design fits easily in tool bags while maintaining the durability required for daily field use.

Ideal for HVAC technicians working with copper tubing systems, refrigeration installations, and commercial air conditioning equipment where nitrogen purging prevents contamination and ensures clean, oxide-free joints.
