Description
USA Lab Ductless Fume Hood (DCH) | Portable Filtration Workstation
The USA Lab Ductless Fume Hood (DCH) is a stand-alone filtration workstation designed to provide continuous airflow for controlling hazardous fumes, vapors, powders, and particulates. Air is drawn through application-appropriate filtration media and recirculated back into the working environment, eliminating the need for exterior ducting or makeup air.
Available in multiple configurations, the USA Lab Ductless Fume Hood provides a portable and adaptable solution for applications including chemical fume control, powder and dust removal, solvent vapor control, pharmaceutical powder filling, light grinding, acid gas fumes, anesthesia gas containment, epoxy fume control, and other laboratory processes that generate airborne contaminants.
Compared with ducted systems, ductless fume hoods can reduce installation costs, simplify laboratory layout changes, and provide energy savings by avoiding the continuous exhaust of conditioned room air. Select the hood size and filtration configuration according to the application, chemical family, loading rate, and required airflow.
