basic dust extractor reccomendations

[Shay Vings]

Looking for a reliable, quiet .5micron extractor for sanding on my midi lathe

Record RSDE1 £140 on special
Numatic NV 750 (Axminster) £220
Camvac GV286 (4inch) via Toolpost £162
Axminster RDC100H £111

I have seen/heard the Record and although the reviews on Record's website are good, it did seem noisy to me.

The Camvac gets a good vote on this forum but is also said to be noisy though you can route the exhaust away to quieten it somewhat

The Numatic gets good reviews on the Axminster website and is said to be particularly quiet, though it is the most expensive.

I would be grateful for any comments on these or similar machines. I am not bothered about collecting chippings and don't fancy the face masks, or extra costs on Microclene units.

Shay, I have the record RSDE2 [basically the same as the 1 but bigger capacity] and an ol axminster ADE1000 chip collector. I use the axminster on the lathe as it is quieter and takes all the dust from sanding [and the chips from turning]. I just use a 1m length of stayput 100mm hose at the end of the usual flexy hose and it works perfectly.

I also have the RSDE2 but I use a 2HP chip collector on the lathe when sanding. The main reason for this was just that the chip collector was better located. But in use, it's quieter and gets 80-90$ of the dust when positioned right. Sometimes I use both if I have a lot of sanding to do. The RSDE2 is the loudest machine in my workshop and I never use it without ear defenders. It squeals like a pig! But then all of the extractors you have listed will be much louder than a chip collector. On the flip side, that type of extractor is the most versatile and will handle pretty much any type of extracting you want to do. I'd suggest going for one with a 4inch inlet. Although the ones with the inlet on the side of the drum are supposed to be more efficient (i.e creating a cyclonic effect) they are restricted to smaller diameter inlets which reduces their versatility.

I would recommend the Camvac

I was looking to upgrade my dust collection last year and had a look at most of the ones you mention, or the available model, but came down in favour of the Camvac. I brought the 336 twin motor and I would recommend any model if asked.

All the Camvac models use the same motor the only difference between them is the size of the drum and the number of motors. The way I have it rigged up when working at the lathe I cant hear the motor only the noise of the air being pulled into the hose.

If you fancy a trip up to Peterborough to see and hear it working you are more than welcome.

....not meaning to hijack your thread Shay, but I'm just looking at changing round my extraction - I've a couple of old 1hp units that are now dead and was thinking of getting a 2 bag/3hp unit to take planer shavings and lathe chippings (I mostly turn Oak).....anyone think I'm going down the right road or see any obvious flaws in my idea?

The machines are in the same area and I need to keep these shavings/chips together for the 'poultry/hamster' people who take away my waste.

I too would recommend the Camvac. Routing the exhaust pipe carefully really does cut down on the noise they make. Our turning club uses a Camvac at demos and we route the exhaust pipe away into a large cardboard box (used for transporting other bits & bobs) which means the demonstrator is able to talk & sand at the same time and the audience can still hear him!

Something I've not seen mentioned on any of the forums and a feature I like about the Camvacs is the two stage filtration - a cloth filter (which is washable) and a paper fine dust filter. In practice I find this makes the Camvac easier and pleasanter to empty compared with some other types which only have a paper fine dust filter (like my Axminster one). The cloth filter prevents the paper filter getting covered with dust and shavings - which then go everywhere when you open the machine to empty it! On the Camvac the majority of the mess is confined to the cloth filter which can be carefully removed and folded up into itself, keeping all the mess inside until you either take it outside for a good shake or dump it in a bucket of water for washing.

thanks for the comments - keep them coming

I just found a Draper drum extractor

http://www.drapertools.com/b2c/b2citmds ... 130&ipadd=

which looks and is specified like the Record RSDE, Camvac 286 etc but has a "tangential inlet". Price seems keen. Does anyone know more about this oddball ?

 

[wizer]

Normally I'd recommend you steer clear of Draper. But that unit looks very interesting indeed. I like the 4inch side mounted inlet.

Hi,

I've got a Record dx4000, which is 2x1000w, 80litre drum and 2 stage filter like the camvac. Vert good suction close in for fine dust but does handle larger planer chips well. Good for the cash but quite loud!

If I ever upgrade, I'll go for the large motor, and cyclone with filter! Like onieda or clearvue! They offer exception air movement and longer lasting filters, as only a small amount of dust gets past the culyclone and drum. Making them very efficent. The main downside is cost, unless you can make the cyclone yourself and the you just need a 2-3hp motor and impellor from a normal chip collector.

I bought one of these on saturday. Marked up at £99.99 but I used 15% discount voucher so I got it for £85

Has proper power take off, I am very pleased.

Hello, can any one tell me what size of ducting you need to attach to the outlets?

I want to try reducing the noise - it works great but when I placed it outside my garage the noise increased in the driveway - which is fine for me in the garage but not for every one else! p

You might want to ask a mod to move your question to a new thread; as it's a slightly orthogonal subject, on a thread that's been inactive for 6 years.

In short, approprite ducting size is important - too small and you kill airflow on a low pressure extractor, too large and you can't achieve enough linear speed to capture fine dust. Lots of info here: http://billpentz.com/woodworking/cyclone/ducting.cfm

However, ducting sizing isn't that much about noise. You could rig up some sort of exhaust + muffler (popular with cyclones) but I don't think you'll change much in that regard (unless perhaps you currently have some spiral metal ducting and it's vibrating severely)?
