摘要

Double-sided fume cupboard, which can be used as room divider between two rooms, has a box-shaped housing with two internal exhaust ducts (50,200), connected via a manifold chamber (40) to an exhaust connection (30). Exhaust slots (60,190) are provided in the ducts at the top inside corners of the cupboard. Vertically slideable windows (150) are provided at either side of the cupboard. Hollow sliding panels (10,20) each have an exhaust slot (80,90) at bottom and top, the upper ones opening onto the exhaust ducts. The panels are connected together by the sliding mechanism (170) so that one is always shut. ADVANTAGE - Two-dimensional flow ensures that hazardous gases do not escape.
