Evapco Low Sound Solutions

The Super Low Sound Fan offered by EVAPCO utilizes an extremely wide chord blade design available for sound sensitive applications where the lowest sound levels are desired. The fan is one-piece molded heavy duty FRP construction utilizing a forward swept blade design. The Super Low Sound Fan is capable of reducing the unit sound pressure levels 9dB(A) to 15dB(A), depending upon specific unit selection and measurement location. The fans are high efficiency axial propeller type and operate with no loss of thermal performance.

are these FRP blades hollow? assuming they are otherwise centrifugal forces would increase shaft loading beyond safe limits, thus being hollow also raises issues of balance and with a design having such large degree of pitch there would be slight contorsion.

Also having fan gaurds removed reduces spl by eliminating 'chop' as the blades pass under the gaurd, perhaps that's why you have increased the height of the fan stack on your fan, doing that would decrease the spl on the standard fan.
