The
air flow is horizontal from HEPA-filter backwall outwards through
the front into room to prevent a backwash of unserile air when
working.
Vertical
Laminar Air Flow
The air flow is vertical drawnflow work station, efficiency
protecting the product against contamination. The unsterile air
is recirculated to clean by HEPA-filter, 50% (Approx.) of air
from vertical to recirculated, so the air is cleaned several time.
Biohazard Laminar Air Flow
The air flow is vertical drawnflow work station, efficiency protecting
the material against contamination. At the same time its offer
well defined operator and environment protection against active
or dangerous work substances. 20-25% of the recirculated air is
exhausted after through the second HEPA-filter.
Double
side Biohazard Laminar Air Flow
The
air flow is vertical drawnflow work station, like model BS. This
model is especially constructed can be performed from 2 sides
as a glass window is mounted on both long sides.
