Tabletop fume hoods, also called countertop fume cupboards, are most often chosen by schools and small labs, their construction is made entirely of galvanized steel without the use of wood-based materials. Window made of tempered glass, manually operated with counterbalance, opened upwards with a lock at 500mm (max 810mm), the window has a system preventing its uncontrolled falling. The DCL tabletop fume hood is equipped with energy-saving LED linear lighting, separated by glass from the fume cupboard working chamber. The double back wall system with extraction slots in the upper and lower sections ensures correct extraction of lighter or heavier than air vapours without turbulence and dead zones.
