Ductless fume hoods for laboratory use employ filtration to capture chemical fumes and vapors, providing a safe and effective means of protecting lab techs from harmful exposure. The environmental and cost benefits of the systems are substantial when compared to exhaust type fume removal methods. Ductless fume hoods purify and recirculate air back into the lab space, negating the need to deliver large volumes of conditioned make-up air to the space.

 While a ductless fume hood will not be suitable for every chemical lab operation, the range of applications where a filtration and recirculation solution can provide a safe and effective alternative are extensive.

• Common laboratory chemicals, especially organic.
• Sulphur dioxide or hydrofluoric acid fumes. Organic and inorganic acid vapors and fumes.
• Mercury vapor and compounds.
• Sulphur compounds.
• Halogen compounds like chlorine, fluorine, iodine, bromine, etc.
• Formaldehyde.
• Ammonia and amines.

Extensive data is available on the use of various chemical compounds with ductless fume hoods. Share your application challenge with a product specialist for the best recommendation.
