Removes water and C5 weight and heavier hydrocarbons from air or inert gases. The inner glass tube contains activated carbon, Co-Free™ moisture indicator and molecular sieve. The CoFree changes from greenish-yellow to blue at low relative humidity to warn of leaks in the gas stream. Gas lines are protected from dust by 10um frits at both ends of the filter. Dual Seal Design: In this design the heavy-walled inner glass tube is protected by a sealed outer plastic tube. This design provides extra protection if the glass tube were to fail, the gas system is still fully protected against leaks. An internal frit at each end prevents particulate contamination. The ZPure Glass Filters and Purifiers are available with standard compression fittings or quick connect fittings in 1/4” and 1/8” brass and stainless steel.

For high purity applications, the ZPure PolyGas II Purifier is recommended over the ZPure H2O/HC.
