What does it mean when I see references to N+1, N-1 when dealing with fan arrays?

N+1 is the practice of having a spare fan to ensure system availability in the event of a main operating fan failure. When not needed, the N+1 fan is not utilized. N-1 is the practice of sizing your fan array so that if one fan fails, the other fans are sized to speed up and makeup for the lost fan performance. In this situation, all fans are being utilized at all times. Your redundancy comes from the existing fans being selected such that they can maintain the required CFM of your system even with a fan failure. For a detailed review of what is best for your application, contact your local ClimateCraft sales representative.

If you have any questions, please contact us.

Note: ClimateCraft’s fan array products allow for fans to be turned off for safety, repair, and maintenance purposes. ClimateCraft’s fan array products are not designed to turn individual fans on and off for the purpose of improving fan array efficiency, and ClimateCraft does not endorse turning individual fans on and off for the purpose of improving fan array efficiency. Any statement to the contrary is not supported by ClimateCraft.
