Western, a Scott Fetzer Co.: Nitrogen Purging Regulators

Two HVAC nitrogen purging regulator/flowmeters are available for the HVAC market. The regulators incorporate a hybrid design and function as both a pressure regulator and flowmeter depending on the position of the control knob. The units are very intuitive to use, with preset purge and braze nitrogen flow settings, and a preset test pressure. Two models are available: 250-psi test pressure and 500-psi test pressure. Both units feature a hand-tight cylinder connection, so no wrench is needed for installation. Other features include a cylinder content gauge, ¼-inch SAE outlet, and heavy-duty brass body. The models allow HVAC technicians to install or repair HVAC systems easily and efficiently, thereby decreasing service call time, said the company.
