The BFF Series ™ is a filter fan system designed to cool your equipment by forcing and draining the internal heat load from your application. The BFF Series™ can be used from a backup filter fan for your application with other primary cooling units (such as AC units) or as a primary cooling unit. No matter how you use BFF Series™, it maintains a closed loop environment in your application when the device is not running. The BFF series ™ combines Ice Qube's unique baffles and dampers system to protect and maintain closed loop environments in applications when not running.
