Remote Cabinet Venting
Inline duct fans can be used venting cabinetry but typically only when added during new construction or renovations. Using ducting to vent cabinetry is very effective, is typically completely silent and reduces the amount of equipment within a cabinet.
It is strongly recommended to use the EC versions these are simply the latest technology and feature variable speed fan control. The EC packages include the controller while the non-EC versions do not and must be purchased separately.
