Adjustable CO₂ flow regulator — set the flow you need, read it at a glance
An Adjustable CO₂ flow regulator from REAL GAZ lets the user dial in a flow rate and see it directly on a graduated scale.
Typical ranges run from a few litres per hour for fine dosing to 30 l/min for welding duty.
Typical ranges run from a few litres per hour for fine dosing to 30 l/min for welding duty.
Adjustability is useful because needs change: a planted aquarium needs a trickle measured in bubbles per second, while a MAG torch needs steady litres per minute. We offer ranges accordingly, and advise on pairing the regulator with a solenoid or timer where automatic control is required. Always open the cylinder valve slowly and check connections for leaks.
Equipment relates to EN ISO 2503 and ISO 5145; CO₂ purity suits food-contact and technical uses.
A few practical tips make adjustable units easier to live with. Start with the needle valve closed, open the cylinder slowly, then turn the valve until the flow appears on the scale. For aquariums, a bubble counter and a fine needle valve downstream help stabilise very low flows, and a check valve prevents water from travelling back towards the regulator. For welding, set the flow while gas is running through the torch, as readings taken against a closed outlet are misleading. Small 2 and 5 litre cylinders suit hobby systems, while 10 and 20 litre sizes suit workshops and larger growing areas.
