Laboratory Fume Hood Model with Exhaust System & Mounting Frame

This technical drawing presents a laboratory fume hood assembly designed for chemical vapor containment in research environments. This model features a rectangular enclosure with approximately 72″ width and 36″ depth, including an integrated exhaust system indicated by the central octagonal duct connection. The drawing shows, essentially, the structural framing with front sash supports and includes mounting hardware at the base for securing to laboratory furniture. The hood appears designed to match international laboratory standards as referenced in the drawing text. Notable design elements include a recessed work surface, reinforced side panels, and provisions for utility connections along the base. The exhaust duct connection is positioned centrally at the top for optimal airflow dynamics, essential for maintaining negative pressure within the containment area. Construction appears to use primarily stainless steel components for chemical resistance and durability in laboratory environments.
