Dear Richard,
You do have a LN or lower noise unit as we stopped bring in the 50Hz
fan models right after John received his. We new he was a sucker, so we
gave him a unit that really sucks. All kidding aside both work very
well, but the earlier models were louder.

Geoff, I bought the AF-22 LN at the IFW show in Anaheim last July.
John Renzetti clued me in on the LN version other wise I may have
ended
up the other as none of the sale people made a reverence to either
one. Anyway the AF-22 LN is my first dust collection system other
than
the old Sears ShopVac I have so I don't really have anything to
compare
to. I will say that I find the noise level of the LN to be quite
acceptable. The pitch of the noise is more of a low sound rather than
the high pitch of my shop vac, when using my AD-471 Jointer/planer I
hardly hear it over the noise generated my the AD-741. Presently I
have the AF-22 LN connected to the AD-741 with a 24' piece of flexible
hose so this put the unit fairly close to the work area. Rich

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!
