I'm looking for a variable speed, not 4, 8, or 12 speed, but something that is truly variable speed that's easy to adjust and a 1HP four wheel. Does anyone know who makes one? Is there a device that can drop the speed electrically if the other options arenít available?

From contributor F:
Univer makes them - better be sitting down when you see the price for a new one though! I have one and it works great, however it doesn't go as slow as my Delta. I think the slowest it runs is about 15 fpm, which is pretty slow. Alternatively you may be able to use a VFD on a regular 3 phase feeder. It's a bit out of my realm of experience though so I'll leave that to the others.
