With the start of the leaf raking/blowing season just a month away, I have been thinking of a way in which I could make my old leaf blower more effective so I can spend less time doing leaf blowing. I know that I can go out and buy a more powerful leaf blower, but before I do that there is an idea that I have that I believe will increase the effectiveness of my current leaf blower.
It would involve building an air amplifier attachment for my leaf blower which would increase the overall air flow by making use of the Coanda Effect. I was inspired with this idea after recently watching a YouTube video on how the Dyson air multiplier fans work.
Please reference the drawing below:
I want to point out that this is a cylinder-shaped attachment which would be made out of a lightweight yet durable plastic and that it would be hollow. Also, it would be designed to attach to the standard leaf blower tube which is 3.5 inches in diameter.
Would this air amplifier attachment increase a leaf blower's effectiveness?
This attachment would most likely need to be screwed on to the tube or held on with a couple of latches otherwise the back pressure inside of the attachment would likely cause it to pop off.
