Normally case of fume cupboard designer, designed the air movement
pass on the working area top, this important reason, the operator
made wrong decission on experiment, we can not control the temperator
of heater for boiling the sample or the glassware have fallen
from windy. The new design make the air movement pass under the
working area top under working area pass system through to the
back of baffle and adjust the flow rate by itself.
Vapours and Odors of most ehemical solvents are unpleasant; moreover,
the air conditioner will cause air circulation that is the vapours
and odors will spread in the room adn directly effect to personal
health. Some solvent effect to respiratory system, bronchia, lung,

The elamination of acid-base fume by water is the easiest way
to make the environment better. The fumes in the laboratory must
be eliminated before emission through the air. In case of using
large amount of acid-base for example, Digestion; acid-base fumes
have to be treated before emitted through the environment. Treating
process is passing these fumes into the pack-media tank in order
to increasing the contact time between the fumes and water spray.
Next, Passing its through 5 micron filter to seperate water spray
from treated fume (cleaned-air). Finally, The remain cleaned-air
is emited through the environment.
