Reverse vacuum

[joedave]

How would I go about creating a reverse vacuum for the exhaust fan? is it easy to do? is it dangerous?

 

I seen this mentioned in another thread but did not give any details as in how it is done.

make a shroud for it and flick the switch on the vacuum for reverse

i see it as a pretty half arsed, non researched idea but.

first of all you have to think about running a vacum for extended periods of time, (not good) and the noise for two.

i just read the post again and i'm pretty smashed so i might be talkin bout something completly different to what you are hehe. therefore making a pretty good job of making myself look like a penis on legs but oh well.

all electric motors have 'brushes' and with most electric motors, they're specifically designed brushes designed to suite the duty cycle :- vacum cleaners aren't designed to be run all the time.
