Description

PDF

This is designed to convert 92mm computer fan into a centrifugal fan. It contains a ducted housing to direct outgoing air in a specific direction. The air enters from the top of the fan wheel, turning 90 degrees and accelerates due to centrifugal  force as it flows over the blades and exits the fan. 

The PC fan needs to be adjusted: The blades of the fan needs to be cut off to easily insert the fan wheel.  Also the sides of the fan body needs to be cut off in the corner around the output.
