Soundproofing an RL-125

I have this machine inside the shop and noise is 94dB twelve feet away making serious ear protection mandatory. ?Thinking of fabricating a hanging enclosure of this material:

Any other suggestions on quieting down this beast? ?? |

开云体育That would work. I also found acoustical ceiling tiles that were made from foam specifically for sound absorption, used them on a house where the return air from the AC unit was right in the hall way off the living room and it sounded like a jet airplane was taking off when the AC came on. Glued the panels inside the box that the air handler sat on and the sound decrease was incredible.The ones I found were made by Sonex, were 2’x4’ and about 2” thick, looked similar the the one in the middle of this picture: Of course, being the cheap ass that I am, I found them on Craig’s List and paid about 25 cents on the dollar for them. Just went and looked, my local CL has a guy selling something that would work right now, $3 a square foot, not sure if that’s a “good” deal or not: Brian Lamb blamb11@... www.lambtoolworks.com On Aug 23, 2015, at 7:02 AM, rcorselli@...

I have RL160 after having a Clearvue for 7 years and there is a major difference in noise and cleanup. The RL160 is much quieter and the bins allow you to machine a lot of wood before empting. They hold 400 liters which converts to about a hundred gallons. Overfilling doesn't clog the filters like on a cyclone but still requires cleanup when you pull the bin out and dump shavings on the ground. Apparently on the newer models you can get a self cleaning but the manual cleaning isn't that bad. David Best has adapted his RL to an automatic cleaner and documented here if I remember right.? Hands down in my humble opinion a better choice but still not perfect. I would have a lot of trouble going back to a cyclone. John On Sun, Aug 23, 2015 at 10:02 AM, rcorselli@...

The noise on the RL 160 running by itself tested at 81 DB in my shop, did you test with an app or a sound meter. John On Sun, Aug 23, 2015 at 10:02 AM, rcorselli@... [felder-woodworking] <felder-woodworking@...> wrote:

John:
Is this is the latest version? ?How are you finding the filter cleaning to be? ?Possible clogged filters and subsequent (unpleasant) cleaning of these filters seems to be have been one of the main issues. ?I'm currently considering getting an RL-160 and trying to get opinions on the latest model. ?There's now even an option for attaching a compressor for pneumatic cleaning of the filters (very expensive option though).

Anil the pneumatic option is to power a hydraulic cylinder to move the brushes instead of manually. I was at our Felder office a couple of weeks ago and took pictures of the setup. Its designed to activate at the end of a cycle when the machine is shutdown. My unit is under a year old with the new style aluminized filters and manual cleaning, no clogging so far and I've changed 2 bags about 50 times since I got it.

Thanx even my old Clearvue wasn't that loud and came in at 89 to 90 DB with the JP running. That's why I ask. You can easily carry on a conversation with just the DC running. John On Sun, Aug 23, 2015 at 11:01 AM, rcorselli@... [felder-woodworking] <felder-woodworking@...> wrote:

开云体育I have a clearview system inside my shop that vents back to the shop. ?The noise level was 93 db from 6’ away.? It was LOUD!? ? I documented the way the noise level was reduced to 64 db in the link below.? I have two shops that are documented in this blog.? Please scroll down quite a ways to get to the heading titled: Installing the Clearview 1800 in my new shop. ? ? ? By the way, I like the idea of moving the DC to a separate building.? My other shop has a CV mounted and vented outside.? It was much easier to install and cost a lot less for material. ?And I don’t have filters to clean. ? Cheers, ? Marty 480-229-0654 ?

When I got mine last year they only had a single phase ?in stock for a sale price and I would have had to wait 2 months for a 3PH. John On Sun, Aug 23, 2015 at 11:17 AM, anil00@... [felder-woodworking] <felder-woodworking@...> wrote:

I have a Clearvue. ?I've never had filters and returned air to shop, but on my first install the exhaust was about 12' long 8" diameter sheet metal pipe exhaust terminating thru the roof. ?It was a bit over 90dB from about 10' away. ? ?Then I changed the exhaust to run immediately out the wall (no duct at all) and it's ~10dB quieter inside. ? So the peak volume was the air banging on the metal exhaust duct inside the shop. ?
Now I certainly can't hear the DC if I turn on the table saw. |

Hi guys. The odd person reports very high noise levels from a given dust system, others not. My CV is pretty ?quiet and unobtrusive ?- quieter than the previous 1 1/2 HP bagger.?
Think it may be heavily down to the specifics of the installation - if you are unlucky you can strike a situation where stuff resonates and makes a lot of noise.? Soft mounting can make a hell of a difference, and is a lot easier than building quiet rooms - put breaks in the ductwork on both inlet and exhaust, and soft mount the fan and cyclone.? This to stop the vibes being fed into the ductwork and building structure. Especially a double break/mount as used in a spin dryer if tuned right. e.g. the CV fan hangs on soft mounts, but in addition soft mount the wall/floor bracket too. Ditto two joints in ducting. ? Adjusting the fan RPM by even a hair in either direction can help a lot if you have a VFD too - it may just be anough to get clear of some resonance or other. A silencer on the fan exhaust (just a fibre packed sleeve - a cheap/stock HVAC part, even a short one) makes a noticeable difference - presuming your installation can accomodate one. It's seemingly possible also to get odd turbulences in the ducting. It's seemingly better for cyclone and fan performance to ensure a short straight run (6 or 7ft) before the cyclone and after the fan if possible… ian |

Although I only described those two configurations, I actually experimented with a lot of variables at various stages, including a full airtight enclosure. ? I found small changes never made much difference. ?
That said, I imagine basic aspects of the building make a significant difference. ?Fwiw, mine is regular wood frame construction, cavities filled with spray foam insulation, an interior layer of plywood with drywall green glued onto the plywood. ?My CV has no mount bracket and hangs directly from the ceiling on rubber-mounted rods. ? ---In felder-woodworking@..., <imaybury@...> wrote : Hi guys.

开云体育Just ordered a sound meter — Amazon prime is amazing! ?I’ll report on Tuesday when it gets here.Mike
|
||||||||||||||||||||||||||
开云体育I downloaded an App to my iPhone, called Decibel. I was having issues with a pool pump where the bearings were going out but because it wasn’t leaking or hadn’t stopped yet, the home warranty folks didn’t want to do anything. We couldn’t sleep at night with the thing running and I’m sure the neighbors were pissed. I used the iPhone to get sound levels and found that I could be ticketed by the police for “disturbing the peace”. In the midst of arguing the issue with the home warranty folks, the seals on the motor blew from the heat and they had to replace the whole thing anyway.On Aug 23, 2015, at 12:09 PM, rcorselli@...
