Fiberglass reinforced polyester fan stacks

Fan stacks are available for all usual fan impeller diameters.

The fibre glass reinforced polyester fan stacks consist of belled inlets, fan rings and depending on  the height – conical, diverging exits for reduced air pressure drop losses and pressure recovery for high fan efficiency.

Fan stack sections are double-walled with smooth surfaces. Vibrations are low due to the thick
walls and stiffening ribs.
