Concoa (www.concoa.com) has designed a gas distribution manifold for its 600 series switchover/ 623 delivery systems. The 629 Series can be configured as a gaseous withdrawal manifold or as a vent manifold, and is suited for laser, metal fabrication and other applications. As a gas manifold with 0.5-in. internal diameter flow path, the company says the 629 Series maximizes gaseous flow capacity from liquid cans or high-pressure cylinders to a Concoa pressure control device. As a vent manifold, the 629 Series provides headspace equalization for multiple liquid cylinders when used with a 629/628 gaseous manifold, to maximize liquid can flow performance.
