More About this Item

Designed for in-line use with stepped barb connection for 10-12 mm ID hose-generally installed on the pump inlet. The filters can be used as a backup between a cold trap and the pump to protect against vapors if the cold trap fails

Activated Carbon is a microporous carbonaceous material that is produced from various raw materials. The granular activated carbon is produced from lignite coal and is acid washed after steam activation. This steam activation process creates pores of molecular dimensions within the carbon particle, yielding a material with extremely high internal porosity and surface area.

Molecular Sieves are crystalline alkali metal aluminosilicates with a three-dimensional interconnecting network structure of silica and alumina tetrahedral. The A family of molecular sieves has been considered the universal product for removal of water from various gases. It will absorb molecules with a size of less than 4A, and exclude those larger.

Desiccant contains anhydrous calcium sulfate prepared from natural gypsum and impregnated with calcium chloride. Its drying efficiency for gases is high because of its superior absorption of water. With the addition of calcium chloride, the desiccant changes from blue to pink as the limit of absorption is reached. This color change is easily seen through the translucent housing.
