The Aeromax Blower Password video explains how to set a password to turn on the blower of a NuAire Biosafety Cabinet featuring the Aeromax control system. Users can enter the password menu by using a specific key sequence and arrow keys to navigate and wave key to accept the time or silence key to abort. This will ensure that the blower can only be turned on with the password that has been set. This feature restricts access to the blower and provides an added layer of security.
