Belmed Defender Automatic Changeover Manifold & Wall Alarm (with pre-install kit)


The Belmed Defender Automatic Changeover Manifold is the perfect manifold solution for your dental Nitrous Oxide Delivery System. The Defender can accommodate two cylinders for both oxygen and nitrous oxide. This manifold is fully automatic and will switch from "in-use" to "reserve" tank without fluctuations in the gas delivery. The "empty" indicator will remain lit until a new cylinder is connected and the appropriate pressure is detected by the manifold. The system is auto-sensing. There is no need to manually reset the manifold after a cylindar change.
