Air Distribution Unit for Racks. Provides airflow for rack enclosures with loads up to 3.5 kW. Connects into the raised floor within your racking / NetShelter (the rack must be installed directly above the opening) and pulls supply air directly into the enclosure speeding up airflow up through the racking. Adjustable Design, Air Filtration, Compact Footprint, Eliminates Air Mixing, Improves Air Circulation, Increases Airflow, Occupies 2U of rack space, Redundancy. Includes rack mounting brackets, user manual. The Rack Air Distribution Unit is a 2U fan unit that works with an existing precision air conditioning system to deliver cool air to the equipment contained in a rack enclosure. The Rack Air Distribution Unit connects into the raised floor and pulls supply air directly into the enclosure. This prevents the conditioned air from mixing with warmer room air before reaching the equipment. The Rack Air Distribution Unit minimizes temperature differences between the top and bottom of the enclosure. It also prevents hot exhaust air from recirculating to the inlet of the enclosure. The product is recommended for rack enclosures with loads greater than 1.5kW and can provide airflow for loads up to 3.5kW. It is also ideal for enclosures in raised floor environments where underfloor air distribution is inadequate. Features: Adjustable Design Air Filtration Dual A-B Power Inputs Improves Air Circulation Minimizes Air Mixing Promotes Proper Airflow Product Features Promotes Proper Airflow: Helps to maintain proper rack temperatures within the enclosure by promoting top to bottom airflow movement Fan Guards: A safety measure that provides protection from the fan opening by covering the inlet Dual A-B Power Inputs: Draws power from the UPS for power protection with dual feeds for redundancy Dual Fans: Provides fault tolerance in the event of a fan failure Fan Control Switches: Users can turn one or both fans on and off depending on the heat load Mount
