Safety Data Sheet

Product Description

Bead form of Alumino-Silicate
High density, Thermally stableSorbead R® is an alumino-silicate. Although we have listed it in our Silica Gel category, it is not truly a Silica Gel, nor is it a Molecular Sieve (another type of alumino-silicate). Sorbead R® is a high-density adsorbent capable of drying gases such as air, Carbon Dioxide, natural gas, Nitrogen and Oxygen to extremely low dewpoints in conditions that render other types of desiccant useless after a relatively short period of time. Rapid regeneration cycles? High pressure application? Wet inlet gas? Sorbead R® was made to perform in difficult environments under difficult conditions and to deliver high quality effluent gas as well as long service life.

*The 30 lb packaging of this item is meant to accomodate the requirements of the Ground Purge Unit (GPU) utilized by the United States Air Force and Air National Guard. The Ground Purge Unit requires 60 Lbs (2 each, 30 b pails) of this product for refill. Sorbead R is the Desiccant specified for optimal GPU function and meets the requirements of MIL-D-3716, Type I.
