  • Page 30 Unique to the Axiom is the Chem-Zone, a directly exhausted work zone. The central portion of the work surface is surrounded by grilles on the sides, front and back. Air entering these grilles is drawn to the Exhaust HEPA filter, and when the cabinet is connected to an exhaust system, out of the laboratory.
  • Page 31 Inlet Relief Valve Also unique to the Axiom is the Inlet Relief Valve, The intake valve is angled such that the incoming make-up (room) air must keep the valve open to maintain normal operation; a loss of exhaust volume will allow gravity and air pressure to close the inlet valve and open the magnetic switch, resulting in an exhaust alarm.
  • Page 32 Exhaust System Alarm The Axiom is unique in its response to an exhaust alarm. Instead of shutting off the BSC’s blowers, the Axiom starts its “Activate Protection Protocol” – a certifier- programmed interval of up to 5 minutes. During this interval, the Axiom’s exhaust blower speeds up to compensate for the loss of the remote exhaust fan to provide constant inflow.

  • Page 34 The modern Class II Biosafety Cabinet was developed in the early 1960’s as a result of the increased availability of High Efficiency Particulate Air (HEPA) filter technology. The motor of choice at the time to drive the cabinet’s blower was the Permanent Split Capacitor (PSC) type.
  • Page 35 testing a prototype model to a variety of airflows and filter pressures, the motor/blower can be “characterized” for that size cabinet. This characterization allows for the creation of a model-specific motor-blower curve. By programming the curve values into the motor during assembly, the motor will deliver the correct volume of air as the HEPA filters load.
  • Page 36 UV Relay Light Relay Outlet Relay RS-232 Board Location The Axiom also has an optional contact/RS232 board. This must be installed if the user wants to signal external building monitors or controllers, or wants the Axiom to output operating information to a data logger.
