Air & Gas Purification

Air & Gas Purification

GAC 3x6 | GAC 4x8 | GAC 4x10

The microporous structure of our coconut shell carbons is especially ideal for the removal of small molecules, such as volatile organic compounds. The activity is specified very precisely for each particular application and the high density and hardness provide a robust bed that withstands intensive use.

Air & Gas Applications

  • Gas purification in chemical and pharmaceutical industry
  • Mercury and contaminant elimination in exhaust gases
  • Collective protection filters for boats, vehicles and buildings
  • Air filters for car cabins and rooms
  • Extractor hoods for universities, hospitals and industrial laboratories
  • Respiratory protection devices (gas masks)
  • Compressed air filters for industrial or breathing air
  • Elimination of contaminants in nuclear energy operations
  • Evaporation control devices for vehicles

Specialized Applications

  • Solvent Recovery: Recovery from viscose rayon, magnetic tape, and acetate plants
  • Gas Purification: Cleaning hydrogen, natural gas, landfill gas
  • Industrial Air Treatment: Capturing VOCs, hydrocarbon, H2S, siloxanes from petroleum, paper, thermal plants
  • PPE: Respirators protecting workers from VOC, acidic/basic gases, ammonia
