NANOCHEM - WeldAssure - Gas Purifiers

NANOCHEM OMX resin also offers efficient removal of hydrocarbons, such as compressor oils, in the gas. A new inorganic media, NANOCHEM ln2Go prevents piping system contamination in the event of a major system upset, such as significant air intrusion or from the accidental connection of an improper cylinder to the purifier. NANOCHEM MSA media is designed to purify Ar/02, Ar/C02 and other 02, C02 blends. Only WeldAssure purifiers specifically labeled for oxygen or carbon dioxide applications can be used for purifying O2 and CO2 blends.

NANOCHEM WeldAssure purifiers are an economical solution for GMAW (TIG) welding and other critical welding applications.
