Lower Fan Tray
Upper Fan Tray

SAIC has designed a pair of fan assemblies to provide superior ventilation for racks with high heat loads and noise level limits. Each tray can be populated with 140 to 190 CFM fans (6 per tray) to provide 840 to 1140 CFM total. The push-pull arrangement provides positive ventilation and minimizes hot spots at the top of the rack. Positive presssurization can be created by proper fan selection. Asynchronous DC fans minimize noise and vibration at single frequencies. The fan selection can be tailored to meet power consumption (efficiency), heat load, and noise level limitations.

 OPTIONS:

UPPER FAN TRAY:

  • A low-loss EMI, drip-proof filter (normally supplied with the rack) is available.
  • An EMI honeycomb or louvered panel is available.
  • A water-cooled heat exchanger to cool exhaust air is available.
  • Unit may be powered from the lower fan assembly or a dedicated DC power supply

LOWER FAN TRAY:

  • Unit may be powered from one or two dedicated DC power supplies.
  • Unit may share power supplies with an Upper Fan Tray.
  • Unit may be mounted above the rack base for racks without bottom intake clearance.
