Laboratory Fume Hood Systems

Laboratory Fume Hood Systems for Controlled Chemical Exhaust Laboratory fume hood systems capture airborne contaminants at the work opening and coordinate the enclosure, exhaust path, monitoring, and sash hardware. This category covers the physical hood, the control and safety accessories used around it, and optional automatic sash equipment. Selection starts with the process hazard and exhaust strategy, not with cabinet material alone.

Choose the Hood Body Before Adding Controls or Sash Automation Use the Laboratory Fume Hoods range to compare ducted, ductless, material-specific, high-clearance, low-flow, and process-specific configurations. Confirm the chemical list, process temperature, equipment envelope, work opening, exhaust connection, room air balance, and discharge strategy. A ductless hood should only be considered when filter compatibility, loading, monitoring, and replacement responsibility are defined for the substances used.

Fume Hood System Accessories include airflow monitors, air-velocity and sash-position sensors, safety sensors, control panels, power components, and drive hardware. Automatic Fume Hood Sash Systems add powered movement, position feedback, and anti-pinch functions. These components support operation and energy-control strategies, but they do not replace airflow balancing, containment testing, or site acceptance.

Information Required for System Selection Prepare the process description, chemical inventory, operating temperature, internal clearance, hood width, sash arrangement, utilities, and base-cabinet scope. Also provide available exhaust airflow and pressure, duct route, room air-balance plan, monitoring and alarm functions, VAV or CAV control, BMS points, and the intended fail-state sequence.

Send the room layout, equipment dimensions, chemical list, airflow schedule, and control sequence to the XICHENG engineering team for a project-specific hood, exhaust-interface, and control-scope review.
