AirBlock Flexible Gap Seals (FGS) from Simplex are designed to increase cooling efficiency in your data center by closing off those hard-to-seal gaps of a 1/2 in. to 6 in. between server racks. The results, according to the company, are drastically reduced energy costs and added capacity in the data center.
The seals attach to the racks with a flexible magnetic side trim. Installation is simple and fast. Squeeze the two magnet edges together and slide into the gap. The magnets seal to the sides of the racks, completing the installation. Trim the seal to fit the rack height with a knife or scissors.
