SCOPE
The fume cupboards ECOCHEM are designed to protect the operator and the environment from fumes,
vapours and smells produced during routine laboratory operations whenever chemicals, reagents etc. are
used.
Their use is NOT recommended for particular workings which do not belong to laboratory routines, such as
those generating large quantities of evaporated solvents, acid digestions and the use with solvents whose
nature, structure and chemical formula are unknown.

SYSTEM AND PERFORMANCE CONTROLS
The fume cupboards ECOCHEM are fitted with regulator in order to keep the airflow speed constant with the
progressive clogging/saturation of the main activated charcoal filter and prefilter.
The control panel is fitted with various controls, such as:
ECOCHEM-S
-
manual regulation for airflow speed
-
hours counter monitoring the real operation time of the fume cupboard
ECOCHEM-M
-
microprocessor for air speed, prefilter and main filter efficiency automatic control
-
alarm devices for low/high airflow speed, device monitoring possible explosive concentrations, motor
fan malfunctioning and gas sensor control
-
hours counter monitoring the real operation time of the fume cupboard and the activated charcoal filter
