Filler Panels, also called "blanking panels", are used to control the airflow inside of server racks. Without the use of blanking panels, the hot exhaust air from the servers can be recirculated through the server rack and back into the servers, and significantly reduce the cooling efficiency of the system. Data centers or IT labs that have Open Frame Racks, closed server cabinets or a 2 Post rack can benefit from the use of blanking panels. Filler panels are the first step towards achieving your Power Usage Effectiveness (PUE) goals. RackSolutions filler panels feature stability flanges keep the filler panel from flexing in and out like most filler panels, an innovative design that reduces the noise when a high amount of air is pushed to the filler panels. Along with the increase in airflow efficiency, RackSolutions filler panels give your rack a seamless and professional appearance. Compatible with all EIA Standard 19" racks and cabinets with square, round and threaded holes.
