John,
Is your AF-22 dust collector single phase? I gather it is based on your
comments of using a standard X-10 compatible wireless 220v switch. At the
other Felder owner's shop in Seattle that I visited yesterday, he told me
about his experience with his AF-22 being too noisy. That unit was also
single-phase. According to the Felder rep who visited, the problem on the
older versions of the AF-22 was that the single-phase motor was rated for 50
Hz, but on 60 Hz it ran 20% faster which threw a big wrench into their
careful system design. They tried to subsitute a smaller impeller, but
couldn't pull the existing one off the shaft. That particular unit went back
to Felder and was replaced with an Oneida 2hp cyclone system.
As you know, I couldn't believe how quietly the used AF-22 I bought with my
BF6-31 ran when I tried it out before buying. That unit is a three-phase
model, and may not be affected by the same issue of running too fast. Not
sure why that would be, but it was something we wondered about while
discussing it yesterday.
Any thoughts, John or anyone else? Does anyone else have an relatively quiet
running AF-22? Single phase or three phase? Anyone have the new redesigned
AF-22LN? How quiet is it? With my preoccupation with power tool noise, maybe
I should buy a sound level meter one of these days!
