Important: this product runs on nitrous oxide (N2 PI), a gas we do not supply and which is currently difficult to obtain. It is your responsibility to find a local supplier of gas for professionals. NOS bottles do not comply with CE standards (they do not carry the PI mark): only CE-approved bottles may be used. European manufacturers offer bottles approved to contain this gas; please check the applicable standards and verify the manufacturer's origin and compliance before purchasing. NOS fittings are not metric (AN / NPT threads depending on the part numbe PI): plan for the adapters needed for your installation. Please comply with the regulations in force in your country.
