This is an advanced-design gas filter for applications requiring high-efficiency moisture removal with the benefit of a depletion indicator. Up to 6 grams water is removed to low-ppb levels. The adsorbing materials are Molecular Sieve 5A and cobalt-free CoFree™ indicator, held in a sturdy glass tube. The gas to be purified contacts only glass, metal and the adsorbents.

CoFree changes color from greenish-yellow to blue at about 5% relative humidity to signal leaks in the system; the molecular sieve removes moisture to trace levels. The glass tube is sealed with a special dual sealing system for extra protection from leaks. An internal frit at each end prevents particulate contamination. The inner glass tube in the CRS ZPure Moisture Trap is enclosed in a plastic outer tube for safety. Dimensions: 3.5 cm x 26 cm, maximum pressure 6.8 bar (100psig).

Dual Seal Design: In this design the glass inner tube is protected by a sealed outer plastic tube. Even if the glass tube fails, the gas system is fully protected against leaks. CoFree changes color from greenish-yellor to blue at about 5% relative humidity to signal leaks in the system; the molecular sieve removes moisture to trace levels. The glass tube is sealed with a special dual sealing system for extra protection from leaks. An internal frit at each end prevents particulate contamination.
