Adjusting the Internal Air Damper

On Type A2 8-inch through 10-inch sash heights and all Type B2 (single blower)
models, during the certification of the biosafety cabinet, it may be necessary to adjust
the split of air between downflow and exhaust. This is an important part of balancing
the biosafety cabinet and hitting the specified average downflow and inflow values
specified for each model and size cabinet.

Note:

On Type A2 12-inch sash height and Type C1 (dual blower) models, there is no

internal air damper.  One blower is dedicated to the supply (downflow) air, and one to
exhaust (inflow) air.  On these models, the blower speed of each will be set
electronically.  See the previous section

Adjusting Blower Speed

, and note the text

“Supply” displayed on Step #5. After setting the supply blower speed, the screens will
advance to the exhaust blower speed adjustment.

To adjust the internal damper, follow these instructions:

1. Remove the front Dress Panel (reference Figure 5-1 and 9-1) by removing the

two (2) Dress Panel Screws, pulling the bottom of the Dress Panel away from the
cabinet, and the lifting up on the Dress Panel.

CAUTION:

The Dress Panel is large and heavy, especially on models 5-feet in width

and larger. Use two (2) persons to safely lift and remove the Dress Panel.
