• Dimensions: 6 x 6 x 6 inches, shipping weight: 0.4 lb
• Requires minimum source pressure 10 inHg
• Replacement component for Accutron/Belmed circuits
• Green zone operating range: 5 to 10 inHg

The Belmed Vacuum Gauge is a crucial replacement component, sometimes referenced by its old designation, old #22122, designed specifically for accurately monitoring and adjusting the vacuum flow within dental nitrous oxide scavenging systems, ensuring safe compliance and patient protection. This gauge is generally integrated into the in-line vacuum suction regulator of the scavenging circuit, which is responsible for safely capturing and removing waste nitrous oxide from the operatory environment.

It provides a visual indicator that the scavenging system is operating within the optimal and compliant vacuum range. Critically, the ideal operating level is marked by a green zone on the gauge face, which indicates a range between 5 and 10 inHg (inches of mercury), which is the precise vacuum level needed for effective capture without creating excessive noise or stress on the system components. The proper functioning of this gauge requires the facility's central vacuum pump system to supply a minimum vacuum source pressure of 10 inHg to the scavenging unit.

If you're searching for a highly effective and reliable tool for superior monitoring and regulation of your nitrous oxide scavenging vacuum flow, the best Belmed Vacuum Gauge is a definitive choice for any dental professional. The physical product is lightweight with an approximate weight of 0.4 lb (pound) and compact dimensions of 6 x 6 x 6 in (inches), making it easy to install as a direct replacement part, and it is fully compatible with both Belmed and Accutron scavenging circuits, guaranteeing consistent and measurable performance in line with safety protocols.
