Square Inline Mixed Flow Centrifugal Fans -FSD
26
26" Duct - 6.993 CFM 208-460/3/60
All FSD Series fans utilize our unique external rotor motors. The motor’s
enclosed design allows the fan to operate in high moisture, lint and dust laden
air. The motors are a permanent split capacitor type, with automatic reset
thermal overload protection and sealed ball bearings. These features ensure long
life and maintenance free operation. All motors and impellers are designed as
one integral unit, allowing for excellent motor heat dissipation, even at a low
RPM.

hemispherical free field calculated per AMCA Standard 301. Values shown are for
installation type A: free inlet fan sone levels. All sone values are calculated
at 0.5” (static pressure in inches W.G.).
‡ Sone Value at 0.75” (static pressure in inches W.G.).
Note: Three phase motors are wound for 230/460 volt. Motors are prewired for 460
volts but may be delivered as 230 volt or may be rewired in the field.
