I need the velocity of a leaf blower! Ideas?
In a nutshell, I have a non-flying related project that I'm working on that I need a good solid stream of air for, well actually several streams. * Think * leaf blower output but trying for quiet for indoor use.
Weight and size are not really an issue, but a larger diameter of air stream would be preferrable - 5" diameter min if possible. I did research on those "high CFM" fans (i.e. shop fans, tubeaxial fans) that Lowes, Home Depot, and several other similar industrial type supply stores sell - but they just don't have the pressure velocity (again, think leaf blower output) I need. Can I use a 12v car battery or ac power motor, hooked up to a EDF setup? I'm a total noob, so I would need simple setup ideas. Thoughts from you creative types??? Thanks in advance! Mike |

5" diameter is well within the range of a propellor..which you could shroud if you want.
since weight isn't a problem, you might as well use an old brushed motor. the biggest problem is that small diameter, high velocity= high RPM = a huge amount of noise. I think you might do worse than to get hold of a buggy motor - something like a 27T one..put a 5x5" prop on it, and connect it to a 12v car battery..be careful though: you will have 1/3rd horsepower of screaming high velocity air and some fast sharp edges..this will at least get you a feel for what sort of power/noise/velocity type issues you can achieve. |

A small centrifugal blower (new) designed for installation in a reed organ (harmonium) or in a very small pipe organ will be very quiet, but not cheap . I suggest that Mike check his area for the local pipe organ service technician, those guys are the biggest "pack rats" on earth, most have a cache or stash of old stuff Cheers, pete |
