9 High-Performance Fans Keep Equipment Cool in Crowded Server Rack Enclosures The SRFANTRAY9 installs easily into 1U of space in an EIA-standard 19-inch rack cabinet. Nine powerful four-inch 120V fans mount low in the rack and push cool air toward the top. These high-performance horizontal fans circulate air at 864 cubic feet per minute (CFM). The fan tray comes fully assembled using heavy-duty cold-rolled steel that’s built to last through constant use. A rear C14 power inlet accepts an AC power cord (sold separately) that connects the fan tray to a conveniently located wall outlet, surge protector or PDU. Better Rack Ventilation Helps Your Valuable Equipment Operate More Efficiently This nine-fan tray is ideal for maintaining a constant flow of cool air within your rack enclosure. Keeping your rack components cool helps boost system performance and avoid costly equipment failures that can lead to downtime, damage and data loss. Note: the SRFANTRAY9 should not be installed any higher than one meter (3.3 feet) off the ground.
