Rack Airflow Management (AFM) requires the prevention of hot exhaust air from circulating back to the front of the rack where it can mix with the cold conditioned air. To achieve this unused rack space should be sealed with rack blanking panels. EDP Distribution offers leading blanking panel solutions from HotLok, EziBlank and PlenaFill.

Once unused rack space has been sealed, other gaps in the rack face should be sealed. These include gaps between the mounting angles and the racks sides, top and bottom. Solutions for doing this come from RackSEAL and HotLok.
