FUME CUPBOARD FUNCTION INDICATOR

The fume cupboard function indicator is situated in/on the pilaster strip on the right side of the fume cupboard.
It indicates the correct functioning of the air flow to the fume cabinet. It monitors the amount of extracted air
and, if necessary, the direct air supply and the air intake connection. It has audible and visual alarms to alert the
user in the case of a malfunction of the fume cabinet.
WORKTOP
 03
The worktop is the upper surface of the platform or the plate which forms the base of the interior of the fume
cupboard.
THE MEDIA EXTRACTION POINTS
 04
The media extraction points are mounted inside the fume cabinet. The controls for the media are arranged on
the outside in the system duct underneath the worktop.
ELECTRIC SOCKETS
 05
The electric sockets are located in the interior of the fume cabinet and in the system duct underneath the
worktop. They comply with protection class IP44. The electric sockets in the interior can be switched from the
outside. The switches are in the system duct and are clearly allocated.
SASH HANDLE BAR

The sash is opened and closed by means of one-handed operation of the handle bar. The sash is unlocked by
turning the sash handle bar (twist-lock release mechanism).
LIGHT BARRIER (OPTIONAL)
 07
The light barrier is mounted in the handle bar of the sash.
It is used for monitoring the automatic closing process of the sash. When the sash is in a downward motion, the
area directly under the handle bar is monitored by a transmit/receive light barrier. Any interruption of the signal
due to reaching into the working area, or devices protruding from inside, causes the sash to stop immediately
(obstacle detection).
SASH LIMITER

In the case of table fume cupboards, the integrated sash limiter is standard. The sash limiter restricts the
maximum variable work access opening of the laboratory fume cupboard. Any further opening is possible only
through a conscious action by the user.

The rod holders are located in the rear panel of the laboratory fume cupboard. They are used to hold
components when conducting experiments.
MOTION DETECTOR (OPTIONAL)
10
The passive infrared detector (motion detector) is located on the front panel.
The motion detector monitors the work area of the laboratory fume cupboard. If no movement is detected, the
sash is closed after the set time.
