The attic fan tends to makes a humming noise when it has a few blades and is running at a high speed setting. Remove the current worn out bearings and replace them. Lint in the vent is the prime cause of vent fires. Blade is made of thin metal sheets in most of the household fans.

If the dryer ducting is going to be more than that add a booster fan and the fan can help move the air that much further. In order to get rid of the hum you need to either operate the fan at a low speed or replace the fan with a new one that has more blades.

The logic behind these booster fans makes simple sense. Shut off the fan before examining the blades and see if there s a problem or not. Remove the screws holding the vent in place. Due to regular wear and tear these bearings can become worn out or lose their lubrication ability.

This will definitely produce noise while the blades are rotating. The warm moist air inside the vent tends to. This can cause the fan to start making constant noise and in some cases even a loud squealing sound. I can feel some water around the metal wrapping of the vent where there is an opening.
