independently of the cabinet. Inlet and outlet ports from the automated decon machine are connected to the
cabinet. The cabinet control system may be set up to run simultaneously aiding the decontaminate circulation
throughout the cabinet during the entire decon cycle.
To validate two decon processes and associated cabinet set up procedure; NuAire utilized a Bioquell Clarus II H₂O₂
and a Steris X10 the following process was performed by the Bioquell Clarus II.
