The working height on this fume cupboard is 540 mm. Type TA-900 TA-540 BA N-TA SF-TA-900 SF-N-TA Design Bench mounted fume cupboard with normal working height Low level fume cupboard with normal working height Walk-in fume cupboard with working height at floor level Low ceiling bench mounted fume cupboard with reduced installation height and normal working height Secuflow -bench mounted fume cupboard with supportive flow technology and normal working height Secuflow -low ceiling bench mounted fume cupboard with supportive flow technology and normal working height On the walk-in fume-cupboard (type BA) the service modules are on a side media bearer on the left or right side of the fume cupboard. On the deep fume cupboard (type TA-540) the service modules are either on the service rail or on the media bearer. 6

9 Description Functional description General purpose fume cupboards are permanently installed fume cupboards connected to a fume extraction system via an extract air collection duct. A partial vacuum is produced in the enclosed workspace by the extraction. Air is drawn in through two gaps above and below the sash. Gases, fumes, aerosols and dust in the workspace are mixed with the air and extracted. Secuflow (optional) Sash The bench mounted fume cupboard SF-TA-900 and the low ceiling bench mounted fume cupboard SF-N-TA are equipped with additional supportive flow technology. The containment is optimised by a fan and slots in the front airflow profile and on the side posts. The workspace is accessible by unsing the sash, moves vertically to open. The bench mounted fume cupboards TA- 900 and SF-TA-900 have a single-piece sash. The other general purpose fume cupboards have a two-piece, synchronously operated sash. Every front sash has two glass cross screens that move in opposite directions. The cross screens make it possible to access the workspace and provide physical protection for the body. On the bench mounted fume cupboard and on the low ceiling bench mounted fume cupboard, a sash hight limiter prevents the sash opening beyond the largest operational sash opening. Before the sash can be opened further, a one-hand release installed on the sash handle must be operated. On all general purpose fume cupboards, an acoustic and visual warning is given when the sash is opened beyond the largest operational sash opening. An anti-skid device prevents the sash dropping if the suspension mechanism fails. A collecting groove on the inside of the sash handle collects splinters and splashes and prevents splashes of liquid escaping from the workspace to the outside. 7

10 Description Sash controller SC (optional) The sash controller SC makes it possible to close the sash with a motorised drive using a movement detector. A photo-electric barrier detects obstacles that protrude out of the workspace. If decected, the movement of the sash is stopped. Function display FAZ The minimum extract air volume is monitored by a sensor. If the flow rate drops below the minimum, a visual indication is provided with a flashing lamp on the function display FAZ and an acoustic indication is provided with an alarm. The alarm can be deactivated by pressing a switch button. Function display FAZ Lamp with switch button for alarm Green indicator with switch button for monitoring function Airflow-Controller AC The Airflow-Controller AC is fitted as an alternative to the function display FAZ. In addition to the functions on the function display FAZ, the extract air volume can be manually increased and reduced on the Airflow-Controller AC. Fluctuations in the ventilation system are compensated. In the simplest case the extract air volume is set to a constant value. As an option the extract air volume can be controlled by the sash position. Variation of the alarm in this case is either in steps or continuously between the min. and the max. extract air volume. The extract air volume is also increased when the cross screen is opened. 8

11 Description A flashing lamp on the Airflow-Controller AC will provide a visual indication and an alarm gives an acoustic indication if control of the extract air volume is not possible. The alarm can be deactivated by pressing a switch button. Airflow-Controller AC Lamp with switch button for alarn Yellow lamp with switch button for max. extract air volume Yellow lamp with switch button for min. extract air volume Green indicator with switch button for regulation function The buttons at the Airflow-Controller AC can also be individually assigned. Lighting The workspace is illuminated. The lighting is designed so that it does not dazzle and can be switched on and off from the outside. On an explosion or deflagration in the workspace, the lighting is raised to relieve the pressure. In this way persons near the fume cupboard are not endangered. Service panels Multiple service terminal Up to three service panels are fitted to the baffle in the workspace. Depending on the equipment fitted, service outlets for e. g. gases, water or for electrical equipment are fitted to the service panels. Several scaffold points for rods with a diameter of 13 mm are fitted to the baffle between the service panels. The multiple service terminals are fitted either in the fume cupboard service rail or in the media bearer on the left or right of the fume cupboard. The service outlets on the service panels in the workspace are operated from the outside using valves or switches on the multiple service terminals. Combinations of fittings and valves are incorporated in water distribution terminals. Switches, sockets or fuses are integrated in an electrical module. 9
