Ductless Fume Hoods for Laboratory Chemical Containment

Air Science ductless fume hoods provide advanced chemical containment solutions for laboratory environments where safe handling of hazardous vapors, fumes, and volatile organic compounds (VOCs) is required. Designed with high-efficiency activated carbon and optional HEPA filtration, these systems protect laboratory personnel and the environment while recirculating clean air back into the workspace.
 
Unlike traditional ducted fume hoods that require external exhaust systems, ductless fume hoods offer flexible installation, lower energy consumption, and improved laboratory efficiency. Air Science Purair® ductless systems are available in multiple configurations to support a wide range of chemical, research, and educational applications.
