I have used these regenerative blowers in the past, they make exellent sources for vacuum tables. http://cgi.ebay.com/ws/eBayISAPI.dll...866984481&rd=1
Until I noticed it was rated at 400hz!
The question I have, I usually see them rated as inches of mercury for vacuum use, this one only shows pressure in h2o. I have searched for some kind of correllation between these ratings with no luck, anybody have an idea of the relationship?
It is too bad this one is 400hz, who uses this apart from the aircraft industry?
