Why Choose Dual Stage Over Single Stage Regulator?

As the compressed CO2 gas inside the cylinder is running low (pressure is low), a single stage regulator has a much higher risk of letting off huge volume of CO2 gas. This is called end of tank dump, the CO2 disaster that can kill all your fish in the aquarium.

A regulator with two-stage regulates the pressure better and maintains stable CO2 output. This eliminates the sudden CO2 dump (can happen due to low pressure) called end-of-tank-dump (EoTD) catastrophe.

The Pro Series dual stage CO2 regulator is your best choice for injecting CO2 to your aquarium

• Pro Series has dual stage structure and safety built-in plus adjustable output pressure

• Expandable manifold blocks with integrated high precision needle valves and bubble counters

• DC 12V solenoid valve is high Performance and uses less power
  

Dual stage structure with adjustable output pressure and safety valve

• Dual stage design, stable output pressure, and eliminates "end of tank dump"

• Pressure knob is adjustable from 0-65 PSI depends on your needs

• Dual gauge indicates tank volume and working pressure

• Safety valve built in. When the pressure is exceeding 100 PSI, the valve will automatically release the pressure

Expandable manifold blocks- each comes with integrated high precision needle valve and bubble counter

• With easy installation you can add or remove additional blocks as needed

• High precision integrated needle valve. Flowrate can be adjusted to as low as 0.3bps

• Bubble counter has check valve built in to prevent water from backflowing into the regulator

• Fits standard 4/6 mm (3/16" inner diameter) CO2 proof tubing

*Fill the bubble counter with fresh water only. DON'T use oil or salty water*

DC 12V solenoid valve, high Performance, cool operating temperature

• This solenoid is designed to work with an automatic timer

• DC 12V solenoid is safe and is much more stable than the AC solenoid

• Low power consumption: 2.5 watts only. keeps the solenoid cool to the touch during operation

• Re-designed solenoid opens and closes smoothly. No more overheating and buzzing sound

The PRO Series Dual Stage Regulator

• Safe 12V DC Integrated Solenoid Valve

• Adjustable working pressure up to 65 PSI

• Made of solid metal material

• High precision needle valve

• Bubble counter with built-in check valve

• Expandable manifold block

• Easy to install – installation tools are included

• North American CGA320 fitting only (not compatible with paintball tanks)

• 1 extra manifold is included (1 is already attached on the regulator). Additional manifold can be purchased

• Take 3-5mins to release the gas trapped inside the regulator when the solenoid is powered off

• While the regulator is powered off, the low-pressure gauge may not show 0 because gas is still trapped inside the regulator. This is normal
