Product Features

  • Safety and Precision- Our regulator has a built-in safety valve with the integrated precise needle valve. When the pressure exceeds 100 PSI, it will automatically open to relieve pressure. The output can be adjusted to as low as 1 bubble every 3 seconds. The bubble counter has a built-in check valve to prevent water from back flowing into the regulator.
  • Dual Stage Construction-This CO2 regulator adopts the dual stage construction which can provide stable output pressure and the output pressure can be adjusted from 0-65 PSI to meet customer s different demands.
  • Stable and Lower Power Consumption- This regulator adapts to 12V DC which is more stable and consumes less power.
  • Material-We used the solid, safe and reliable materials and its pressure resistance capacity is more stronger than that of ordinary aluminum pressure reducing values.
