Medical Oxygen Single Stage Manual Gas Changeover Manifold Panel High-Purity Two-Stage Manual Gas Manifold Gas Pressure Control Panels

Medical gas manifold systems are critical for ensuring a safe and consistent supply of medical gases, such as oxygen, in healthcare facilities. These systems regulate high-pressure gas from cylinders to safe, usable levels for patient care. Two types of manual gas manifold panels—single-stage and two-stage—are commonly used, each serving specific needs based on pressure control and gas purity requirements.

Single Stage Manual Gas Changeover Manifold Panel
The single-stage manual gas changeover manifold panel is designed for primary pressure control of medical oxygen in small to medium-sized hospitals. It reduces high-pressure gas (up to 230 bar) from cylinders to a lower, safe pressure (typically 4.2–10 bar) in one step. This panel is compact, cost-effective, and suitable for non-corrosive gases like oxygen with purity levels up to 99.995%. Key features include:
– Manual Changeover: When the primary cylinder bank is depleted, staff manually switch to the reserve bank, ensuring uninterrupted supply.
– Pressure Gauges: Display cylinder and outlet pressures for monitoring.
– Safety Features: Equipped with relief valves and alarms to alert for low or high pressure.
– Construction: Made with high-purity brass or stainless steel to prevent contamination, with Teflon gaskets for medical-grade sealing.
This system is ideal for facilities with simpler gas distribution needs but requires manual intervention for cylinder changes, making it less automated than other options.

High-Purity Two-Stage Manual Gas Manifold Gas Pressure Control Panels
The two-stage manual gas manifold is designed for high-purity gases (up to 99.9999%) and applications requiring precise pressure control. It reduces gas pressure in two phases: the first stage lowers high cylinder pressure (e.g., 230 bar to 8–10 bar), and the second stage fine-tunes it to a stable delivery pressure (e.g., 4.2 bar). This ensures consistent output despite cylinder pressure drops. Key features include:
– Enhanced Stability: Maintains constant delivery pressure for critical applications like laboratories or ICUs.
– High-Purity Materials: Uses corrosion-resistant materials like brass or stainless steel for toxic or high-purity gases.
– Manual Operation: Requires manual switching between cylinder banks, with clear pressure gauges and LED indicators.
– Safety and Compliance: Includes alarms, shutoff valves, and compliance with standards like NFPA 99 and ISO 13485.

Both systems ensure safe gas delivery but differ in complexity and application. Single-stage panels suit basic needs, while two-stage panels are preferred for high-precision, high-purity requirements.
