1/8 in. (3.2 mm) Bead Size





1/8" (2-5mm) bead activated alumina is the size most frequently used in regenerative dryers. Activated alumina is a porous form of aluminum oxide. It has a high surface area which adsorbs vapors without any change in form.

If size is not known or specified, the 1/8" (2-5mm) size is usually satisfactory. However, if activated alumina is used in a regenerative dryer and the desiccant retaining screens cannot be measured, the 1/4" (5-10mm) size should be used as a bed support (6" layer).

The industry-standard activated alumina desiccant is used extensively in compressed air dryers. Activated alumina is for use in both heated compressed air dryers and heatless / pressure swing compressed air dryers. Dewpoints to -40°F and lower may be achieved with activated alumina depending on dryer design and operating conditions. F-200 is a smooth sphere of activated alumina produced by the unique manufacturing process.

F-200 is an excellent desiccant for drying a wide variety of liquids and gases. Although all molecules are adsorbed to some extent on F-200 activated alumina, those molecules having the highest polarity are preferentially absorbed. Stream conditions such as pressure, concentration and molecular weight of the molecules, temperature and site competing molecules affect the efficiency of adsorption.
