When space is tight, Fantech's RE Series is the solution. With a lightweight, low profile design, and duct diameters from 6" to 10", RE Series fans move a lot of air from one or more venting points. For roof mounting, these fans are available as either a flat plate or with a roof curb design. RE Series fans can also be mounted on an exterior wall when roof access is not suitable. An added benefit is whisper-quiet interior noise levels (depending on type of installation).
