The Gas Dry Purifier is a moisture and dust filter suitable for drying laboratory air or central air supplies. It has a high-strength polycarbonate body with aluminum endcaps and standard brass compression fittings. The filter is filled with molecular sieve and a silica-gel based moisture indicator that changes color in the presence of water.

For applications requiring very high levels of purity we recommend using one of the chromatography-grade gas purifiers, such as the ZPure Glass Moisture Trap (202234-B or 202236-B) or the ZPure H2O Purifier (202230-B, 202231-B, 202230-SS or 202231-SS) if no visual indicator is required.­
