This 5 l CO2 cylinder with its valve is intended for aquarists who run a planted tank and need a steady supply of carbon dioxide for plant growth. It is sold as one unit, so the valve and cylinder are matched from the start and do not need to be sourced separately.
Why it matters
- Valve rated to 190 bar: the valve includes a safety device rated up to 190 bar.

- Certified construction: the cylinder is painted to PN EN 1089-3, carries the European Pi conformity mark, and is marked with DIN and ISO references. Periodic legalization is valid for 10 years from the production date within the EU.
- Seven-year warranty: the warranty is granted at the time of purchase.
