KO-AWFP2 Fan Kit
KO-VT3 Vent Panel Kit

A Selectively Vented Rear Door can be modified as needs grow. Install vents, filters, or fans to improve the operating temperature of racks according to changing thermal requirements.
Active or Passive Thermal Management
Smart configurations of rear door knockouts can resolve active and passive thermal management challenges. Don't just collect hot air. Middle Atlantic knockouts are made for convection strategies that let cool air in while hot air goes out.
