Description
Automatic Changeover Pressure Regulator & System
Drastar AC700 Automatic Changeover Pressure Regulator and System to provide high flow gases from both cylinder or supply lines continuously and stably in the fields of hospital, pharmaceutical line, research labs, etc. Drastar AC700 Automatic Changeover Pressure Regulator system is a wall mounting type (standard) constructed of changeover system and regulator.
Features
- Standard outlet pressure ranged are 0.1 – 2, 0.1 – 5, 0.1 – 10 or 0.1 – 20 bar.
- All pressure ports are ¼” NPT as standard with a Cv value of 0.2.
- Hastelloy-C diaphragms are available as an option for compatibility with corrosive gases.
- The automatic changeover from cylinder (or gas line) 1 to cylinder (or gas line) 2 occurs when the pressure in that cylinder drops below a pre-determined pressure.
- suitable for hospitals, pharmaceutical lines, research and academic labs and is suitable for cylinder gas delivery or bulk gas lines.
- Gas for analysis applications
- High purity gases
- Mixing gas
- Corrosive gases
- Brass or 316L stainless steel body materials
- -40°C to +70°C operating temperature

How-to-use and matters to note
1. Connect the gas cylinders both to the left and right connection holes of the system.
a) To prevent back flow, check valve in between the gas cylinder and AC system MUST be installed.
2. Choose the cylinder (left or right) to use the gas first and set the knob to that cylinder direction.
3. If gas from the first cylinder (A) is consumed or the pressure drops below the working level, the system automatically changes the gas supply cylinder from (A) to the secondary cylinder (B).
a) The knob does NOT turn automatically but can be turned manually tuning to the cylinder which currently supplies the gas.
b) If the first consumed gas cylinder (A) is replaced with new one while the media is still flowing from cylinder B and the arrow is indicating (A) cylinder as it was not set manually to the secondary cylinder, then cylinder A will supply the gas again in compliance with the knob’s direction.
c) Recommended NOT to leave both cylinders empty simultaneously to prevent from gas leakage.
