972 CFM Intelligent Variable Speed Fan Panel (Master) - Front Inside / Rear Outside Mount

The MRF-33.9A is a vertical Door Mount 33U Master Fan Panel that can be linked to RF-33-9A/B or MRF-1-(3, 6 or 9) models. The "A" model can be mounted on the rear door outside or front door inside. Up to 16 fan units can be connected by daisy chain and remotely accessed by one single IP address. Maximum 30 x daisy chain group ( i.e. 480 x Fan Unit ) can be remotely managed by the free GUI. Front panel LED and buttons allow local monitoring and individual fan kit switch on / off.

  • Improves extraction of heat from high density rack
  • 1 x master IP fan unit allows access to 16 fan unit levels over internet
  • Auto & manual CFM (~972) setting reduces power consumption
  • Temperature sensing technology adjusts the fan speeds accordingly
  • Fan speed can be adjusted automatically per temperature detected by the sensor
  • Unit or individual fan on / off ( remote or local )
  • Meantime before failure : 50,000 hrs

The Master IP Fan Unit is bundled with internal IP dongle for connection to WAN. Hence, it is applied as the 1st chain, whereas a Remote Fan Unit without built-in IP dongle will be located to the 2nd to 16th fan unit levels
