389D000 Rev B 5Padded Bypass ArmrestThe Armrest pad is made out of EPDM sponge material which is resistant to most chemicals as well as UVexposure. The pad is held in place with an adhesive and can be easily removed for cleaning. It can also beautoclaved. When the view screen is fully closed, the perforated armrest provides an air bypass that allows airto continue to enter the front Work Surface perforations. This helps minimize noise.UniPressure™ PlenumThe telescoping positive pressure plenum provides a more even clamping force on the HEPA filter frames andprovides more uniform down flow air.Motor/Blower AssemblyThe motor and blower are built as a single assembly in order to minimize vibration.Air Pressure GaugeThe cabinet has an analog air pressure gauge which displays the cabinet’s negative static pressure.The displayed value during operation should remain consistent with the recorded value in the most recentcertification report. However if drastic change is noted, this should be cause for investigating the reason.This device is not intended to be used for air flow set-point verification.Cable PortOne cable port is located in the cabinet’s right side wall. Cable ports provide a safe means of introducing powerand/or data cables, siphoning tubes, etc. into the work area of the cabinet without having to use the front viewscreen access opening. A sealing plug is provided for each port, for use when the port is not required or whenthe cabinet is being decontaminated.Additional cable ports are available in either left or right side walls.ReadySAFE™ ModeThe “ReadySAFE™ Mode” is a feature that reduces the total airflow and energy consumption when the cabinetis not being used. Operation of the cabinet in “ReadySAFE™ Mode” maintains personnel, product andenvironmental protection.Power/Processor Fault AlarmThe Power/Processor Fault Alarm provides a visual and audible alarm when the system experiences a poweroutage or the microprocessor/controller has a fault.
