I've been using the same thing = for 10-15 years. It was specifically made for computers, but is very nice for our = use as well. These can be purchased from computer stores and your local vacuum = cleaner dealer.</FONT></DIV> <DIV><FONT face=Arial size=2>One caution: The one shown has an "adapter/modulator" that allows you to govern how much outside air is = put into the vacuum. If you close that off, completely, the likelihood of burning = out your vacuum is good, so adjust it so that some outside air is allowed = in. I.E., closed it makes your vacuum work too hard. It is a good idea to monitor = how much heat your vacuum is putting out. Warm is o.k., Hot is = not.<G></FONT></DIV> <DIV><FONT face=Arial size=2>Joe Garrett, R.P.T.<BR>Captain, Tool Police<BR>Squares R I</FONT></DIV></BODY></HTML>
