Fantech FSD20 Inline Square Centrifugal Fan, Galvanized Steel Housing 3225 CFM

Their performance is a balancing act

Our FSD Series fans offer substantially quieter performance, simpler installation and easier system balancing than other arrangements. The mixed flow centrifugal type exhaust/supply fan is specifically designed to bridge the transition from axial to centrifugal by combining the high flow of axial designs with higher pressure, non-overloading characteristics of backward curved impellers. Fantech's "The Straight Way" inline designs minimize system losses while being extremely compact. The square inline design keeps air moving in larger ductwork from 18" to 26" square duct dimensions. 100% speed controllability gives extreme flexibility where there is need for varying airflow.

Total control for optimum results

With FSD Series fans, system balancing is achieved by measuring the system flow or pressure and adjusting the fan performance by "dialing in" or setting the fan speed using inexpensive solid state speed controls, transformers or VFDÕs. Direct drive eliminates the need for continuous belt alignment, tension adjustment and ongoing maintenance.
