Acid Fume (white smoke) Collection System


  1. It is suitable for acid fume(sulfuric acid, hydrochloric acid, phosphoric acid, hydrofluoric acid, ammonium fluoride and ammonium chloride) treatment.
  2. It doesn’t have to add any chemicals for inorganic acid fume treatment, but it needs some chemicals additive (e.g. oxidant, reducing agent) for hydrophobic fume treatment.
  3. The removal efficiency of Hydrofluoric acid (HF), hydrochloric acid (HCl), sulfuric acid (H2SO4), nitric acid (HNO3), ammonium chloride (NH4Cl) and ammonium fluoride (NH4F) is very good.
  4. There are many users of this technology including AUO, EPISTAR, PSI, etc.
