In general
The pressure in CO
2
bottles is much too high to be handled safely without a proper pressure regulation. Solenoid
valves, used for aquaria, are safe for a pressure up to a maximum of 10 bars. Standard tubing may be used up
to 1 bar, special CO
2
tubes up to 6 bars. The pressure in a CO
2
bottle varies, depending on the room temperature,
between 60 and 70 bar. In order to reduce this pressure down to the optimum working pressure of the Aqua
Medic CO
2
system, a pressure regulator is needed. The CO
2
pressure regulator regular is best suited for this
purpose. It is a rugged instrument, engineered to withstand regular use while providing sufficient delicate
regulation. The pressure regulator regular is a complete top class instrument. The whole unit is chrome-plated
to improve the corrosion-resistance.
The unit is fitted with 2 chrome-plated pressure gauges. The primary pressure gauge shows the CO
2
pressure
inside of the bottle. This pressure is 60 - 70 bar as long as there is liquid CO
2
left in the bottle. The second
pressure gauge shows the firmly adjusted working pressure of 1.5 bar (between 1 and 2 bar).
