PROBLEM CAUSE REMEDY
During work, an alarm sounds, the
laminar airflow works regularly,
and the velocity of the protective
barrier is reduced by about 30%.
Alarm: “barrier and exhaust fan" The exhaust fan is out of order See the above-mentioned
problem “Alarms: low barrier
velocity”.
IMPORTANT: if this problem
occurs, the material present in
the work area is not damaged,
the
laboratory is sufficiently
protected by the protection
barrier assured by the main fan
and by the design characteristics
of these cabinets.
If necessary, you can continue
working under protection, but
avoid quick movements and
large flames and do not place
large objects under the airflow.
During work, the laminar airflow
seems to work regularly, but the
alarm
“Barrier velocity” starts
sounding.
Exhaust and main filters are
clogged Replace HEPA filters
