Hydrosil’s HS-400 is a spherical activated alumina that is impregnated with no less than 4.0% weight potassium permanganate (KMnO4). The media shall have 2.0 pounds of potassium permanganate per cubic foot. The HS-400 is found in exhaust systems, air dryers, and general HVAC applications.
HS-400 is activated alumina impregnated media and HS-600 is zeolite impregnated media. Both medias are impregnated with potassium permanganate (KMnO4) which oxidizes acid gases and odors. The HS-600 is a harder material than the HS-400; Therefore, the HS-600 will result in insignificant dusting. Depending on the application, Hydrosil will suggest either the HS-600 or HS-400.
