It depends on what you want the fans to achieve.
Please the fan bible "Woods Flakt Fan Engineering Handbook"

Re: Parallel use of Centrifugal fans in HVAC
Fans in parallel = double the volume same pressure
Fans in series = same volume double the pressure

Re: Parallel use of Centrifugal fans in HVAC
It depends on your requirement (flow and sp).
Operating fans in parallel approx. doubles the flow and increses the static pressure slightly.<"No one is so smart, they just stay with problems longer and use their imagination">
