Vapor Phase, Potassium Permanganate

HS-600 Vapor Phase, Potassium Permanganate

Hydrosil’s HS-600 uses reactive chemistry to oxidize various pollutants. The HS-600 is zeolite impregnated with 6% potassium permanganate (KMnO4). Its’ high impregnated level of KMnO4 and insignificant dusting attributes make it an ideal media for gas phase filtration. The HS-600 is designed for removing acid gases, aldehydes, amines, and various hazardous air pollutants. The media is typically used in the following industries:

  • Fresh fruit and vegetable transportation
  • Refineries
  • Pulp and paper mills
  • Ground water remediation
  • Wastewater treatment

The media is loaded in tanks, exhaust systems, soil vapor extraction (SVE) systems, air filtration trays and modules. To see if the HS-600 removes a specific pollutant please see our Air Pollutants page, or contact a representative today.

What’s the Difference Between HS-600 and HS-400?

HS-600 is zeolite impregnated media and HS-400 is activated alumina 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.
