Desiccant Dryer Assemblies remove the smallest traces of moisture from compressed air systems. Moisture absorbent beads remove moisture through chemical reactions.

Desiccant beads change color from blue to pink when saturated. The use of filter units is recommended.

Note: Units equipped with polycarbonate bowls are not compatible with certain chemicals. Please reference the FAQ section of our website under “filters” for a listing of known chemicals that should not be in contact with the polycarbonate bowls.
