What was changed on the AF-22 LN to make it Low Noise?

..Geoff

Tom,

If you want to remove yourself from the group entirely, just send a blank
e-mail to felder-woodworking-unsubscribe@... (these instructions are
also at the bottom of every message from the group).

If you want to stay a member of the group, but not have the e-mails sent to
you, visit and
click on the "Members" tab. You may be asked to establish an eGroups account
to use some of the web site features, and that is easy to do if you follow
their instructions. Once you get to the members tab, you can find your own
name and click on it. There you can view and set your membership options,
including whether you want messages delivered to you via e-mail, or if you
prefer to read them from the web site at your convenience.

Hope that makes sense! I can also make these changes for you should you have
difficulty getting it to work - just send me an e-mail and tell me how you
want it.

Dear group,

I will try to respond to questions or comments and new ideas as soon as
I can. However, if you have problem that needs urgent attention please
email me directly at: john@... or call me at: 1800-572-0061
toll free.
New ideas or product quality remarks will be forwarded to our factory.
There the R&D department will consider the info as they have for years.
Some times changes come quickly and sometimes they come slowly.

I look forward to hearing from you,

John Hartshorne

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!

Dear John,

The AF-22 you have is quite noisey due to the fact it is running a 50Hz
impeller(Fan)with the 60Hz moto it is running almost 20% faster. The on
thing we can say is it really sucks! Reguarding fan balance it is
static balanced
and there for you see a little wobble at the end of the shut down
cycle( after the power has been turned off)this is normal. However a
quality motor shop could balance it as an assembly. I don't know the
cost it could vary depending where you have it done.
Thanks,
JH

My AF22 is single phase. And it is one of the noisey ones. I use the
x10 remote on it and that works fine. When Geoff visited the shop

about

six months ago he noted that the motorfan may be slightly out of
balance which may account for the noise. I'm going to check with John
Hartshorne to see what recommendations there could be to check for
balance. One thing I'd like to see Felder offer is a larger pleated
drum filter. The regular is great but when you use a drum sander or

cut

mdf or other sheet goods, you have to be careful it doesn't clog too
quickly. More frequent cleanouts of the pleats are necessary to get

out

the superfine particles. Still it is compact and very powerful. I
wonder if I could retrofit the new LN motor and fan.

Hi Group,
David's chess tables are candy for the eyes. But most importantly he
makes them on a Felder BF6-31. the joinery is a two flute glue joint
cutter also a Felder product. It works very well.
Enjoy the site,
JH

PS I also added txt files along side the doc files over in the vault.

...after looking around, I'm having a (single phase) Oneida 1.5 hp. system shipped to me this week - will post after I've had it hooked up - they claim 75-80 db (Leeson 3450 rpm motor) and also offer a silencer to further reduce noise.? I've also built a simple relay system that allows control of my dust collector from any machine location - control wires @ 24 volt, so any small 2-wire jacketed wire works great (phone wire, thermostat cable, etc.) simple off-the-shelf Grainger parts, about $35 in parts.? Email me off list if you want specifics.

It's been my experience that noise in fan systems is almost always a fan balance problem - cheap collectors are notorious for out-of-balance fans - Oneida offers a balanced refit for the 2hp Taiwanese fans that's supposed to cut noise and vibration tremendously.? I'm surprised that fan noise would be much affected by the speed difference between a 50hz and 60hz motor - suspect that Felder's fan source has some QC issues...
?
Hearing protection is critical!!!? Those who know about these things claim that 5 minutes exposure to levels exceeded in woodworking can cause permanent and irreparable damage - I've got 30 years in the trades, and, like a fool, worked without hearing protection during the first part (as we were all too macho to wear headphones), causing significant hearing loss.? My solution, after trying every headphone available, is to go with the cheapie foam plugs (connected with an orange plastic cord - Grainger again...) AT ALL TIMES!? They're comfortable enough to wear all day, and you can converse while wearing them when the machinery is off.? I've got a set of Peltor phones for short -term realy noisy stuff like planing - they'll knock off a couple more db than the plugs.? Like everything else, hearing protection becomes a habit -

I cannot respond regarding three phase vs single phase in the Felder AF-22,
but my BF7-41 originally shipped with single phase motors which were (in my
opinion) noisy and caused the machine base to vibrate. Felder graciously
swapped out the motors for three phase which were quieter and produced
dramatically lower vibration.

Felder hinted that the single phase motor supplier was providing motors that
had a wide range of these characteristics...that is some were as quiet as a
three phase and some were much, much noisier. I don't know if the same
supplier is used for the dust collector.

Single and three phase motors should produce roughly the same rotation speed
when powered from the same line frequency. The synch speed is obviously the
same and the slip is within a couple percent.

I use a single phase 3HP Leeson powered blower exhausting a cyclone and it
sounds like an F-16! I have mounted the unit in the attic above my garage
to keep the noise out of the working area. I have yet to complete the air
ducting, so I hope this works out.

Group -

We're on our way to 40 members! Congratulations! It looks like we're getting
off to a great start, but there are a few bumps in the road I need to
comment on.

1. Duplicate subscriptions... it appears a couple folks received invitation
e-mails to both their work and personal e-mail accounts. If this happened to
you, and you replied to both invitations, both of your e-mail accounts will
be subscribed. Sometimes that is nice to be able to read group posts both at
home and at work (while on break, right?? [grin]). However, if this is not
what you wanted, from the e-mail account you do not want subscribed, send a
blank e-mail to felder-woodworking-unsubscribe@... ... if that
doesn't work for you, send me an e-mail (Geoff@...) and I'll remove
whichever account you tell me to.

2. Uploads to the Vault... we have this exciting new capability to share
pictures and documents on the group's web site
(); note that you'll be
prompted to create an eGroups account if you haven't already - it's easy. I
want to encourage everyone to upload relevant stuff there rather than send
e-mail file attachments. It would greatly help things if we commit to using
a handful of common file formats that everyone should be able to use.

o JPEG for photos (saves room)
o GIF for drawings/diagrams (does well with line drawings)
o HTML, PDF (Adobe Acrobat), or plain TXT for articles

Please make sure your upload has the proper file extension (three of four
letters after the dot, as in "My_Shop_Pic.jpg"). Although it is convenient,
I don't recommend we use Microsoft Word (".doc") format in the Vault. The
problem is not everyone owns a copy of Word. However, there is a free Word
viewer application on Microsoft's site. It is better to export your articles
to HTML, PDF, or plain TXT before uploading. Some word processors can export
to PDF, so that is a good choice for mixed text and graphics.

As Paul Schumacher pointed out, it would be good if everyone who uploads
makes it easy to identify the author/owner of the file - either make your
own folder in the appropriate place, or change the filename to something
like "Making_Perfect_Sawdust_by_Geoff_Shepherd.pdf"... remember to keep the
correct file extension on there or it is very difficult to tell what kind of
file it is and what is needed to view it.

3. E-mail format... if you can, please set your e-mail program to send
messages in Plain Text rather than HTML format.

Thanks for putting up with my little lectures! ;-)

I have a 3 phase AF-22 and it's very noisy so I definitely wear ear
protection every time I turn any of my machines on.
