Professional Aquarium CO2 Dual Stage Regulator. 

This regulator minimise increase in output pressure as pressure drops in gas cylinder and will prevent end-tank-dump. 

With optional World Class Advance Precision Needle Valve by SMC. Adjustable up to 1 bubble per 10 second.  

  • Quality design and construction achieves excellence in control.
  • Adjustable working pressure up to 5 bar (will let you run more than one diffuser)
  • Dual gauge pressure indicators (tank volume and flow pressure / working pressure)
  • Industrial-grade Precision Needle Valve.
  • Innovative design provides extreme accuracy, dependability, and extended service life.
  • As pressure drops in the gas cylinder, our regulators are designed to minimise the resulting increase in outlet pressure, thus resulting in reduced gas costs, reduced cylinder handling, and improved accuracy.
  • The thread is made according to UK, Europe, Japan and Taiwan standard (BS341 / DIN477 / W21.8), If CGA320 thread required please make note during the checkout process.
