Comment on Students’ Leaf Blower Suppressor To Hit Retail

There’s no way this won’t affect the final CFM or Velocity of the air.

This would be no different than running it at a little less than 100% power, but wastes that energy instead.

Why else would they not provide any technical detail, even a wind velocity test would be huge FFS.

I don’t know, it sounds like it slightly redirects only the air at the margins that contacts the blower tube, which reduces turbulence. The noise reduction is due to the decreased turbulence, not a reduction in airflow. If I had to guess, the actual reduction in airflow is probably negligible, and they don’t describe it in more detail because they’re trying to commercialize it

  So they could provide the testing data to prove it. Even the numbers, don’t need a full detailed video.
  
  The lack of proof to their claims is concerning.

    You seem really worked up about these undergrads’ project

    I thought having a conversation about the validity of their claims would be an okay thing to do in this community?
    
    Or are you saying this place is for something else?

They wont release anything because the design is being sold to black&decker, yay

  As soon as it’s out to market someone will clone it and have an STL available

    it literally doesn’t matter because most people don’t 3D print

  I’ve read the article attached, the article linked, and the video linked as well.
  
  Not one talks about anything technical other than it doesn’t decrease the power, so where’s the stats to prove it? You can’t silence or muffle something without a tradeoff, we ignoring basic physics here?
  
  So what does your comment prove?
