Duplex PNP50 Two-Stage Gas ManifoldIntroduction

The GCE Duplex PNP50 two-stage manifold is engineered for hospital pipeline systems, offering a reliable medical gas source with an integrated third source entry point for LOX, compressors, or other backup sources. This manifold reduces gas pressure in two steps to ensure a constant distribution pressure. It features an innovative touchscreen alarm displaying all three sources. The Duplex PNP50 gas manifold supports medical gases from cylinders of 300 bar, 200 bar, or 150 bar, providing a fully automatic changeover system with advanced communication protocols for seamless integration.
