A highly porous material, this material can have a surface area significantly over 200 square metres/g. Very suitable for use as a filter of fluoride, arsenic and selenium in drinking water
It has a high surface area which adsorbs vapors without any change in form. Will not soften or disintegrate easily when immersed in water.
Dew points to -40°F and lower may be achieved depending on dryer design and operating conditions.
The 1/8” (2-5mm) bead is the size most frequently used in regenerative dryers.
The 3/16” (4-8mm) bead is used when pressure drop and surface area requirements fall between 1/8” and 1/4” material. It is suitable for most systems.
The 1/4” (5-10mm) is used both as a pre-bed material to support large desiccant beds or as a buffer for silica gel beads. Pressure drop is slightly lower than 1/8” (25mm) material.
If size is not known or specified, the 1/8” (2-5mm) size is usually satisfactory.
