What size?

[dicktimber]

What is the minimum \airflow I need when extracting from a PT?

:roll: I have a small record canister type wit Airflow of arrd 400m3/hr, but to be honest it doesn't work well on a 100mm hose.
The reason I ask is that there is a great jump in price from a 850m3/hr extractor and a 1,500m3/hr extractor.

Any thoughts?

you need to look at your maunal as all will be different. Not surprised that a ship vac won't do it, they have high suction but low flow

I have Charnwwod dust/chip extractor that works great on my 10" SIP and my 12" Delta (also on the tablesaw and router table)

Dick, as Tony said, it should tell you the min in the manual for your P/T.

In my experience with the generic oil drum with a motor stuck under the lid is they aren't that good for the high volume of chippings from a P/T, they certainly need a min 4" hose imho.

You might be better looking at something like the Scheppach HA2000 or HA2600 and it's similar clones, these type of machines are designed to move high volumes of planer chippings.


Hope this helps

I have the perform one from Axminster, I think it was about £149, this is more than ample for my Jet 310, I think its a very good machine for the price.

Axminster recently told me that for a 10" wide planer-thicknesser, you need an extractor with an airflow of 1150m3/h minimum. My old Perform machine has slightly less than half that so, on their recommendation, I went for the ADE1200 (actually, I found one on eBay! :wink: ) and I've been very impressed with the results.

I think this is an excellent extractor for the home workshop. Less than 5ft tall with a fairly small footprint for a twin-bag extractor. The collection bag has decent capacities but, if you do a lot of work, you may need to empty it quite often. It also does a great job at keeping the bandsaw and router table clean. Plus, it's very quiet-running - unlike your shop vac.

As long as you don't let your collection bag overflow and beat the dust out of the filter from time-to-time, you'll be amazed at how strong the suction can be on this machine! :wink: I recommend it.

Mike,

I use a WV1000 (I think) from Axmonster, which they seem to say has a flow rate of 200 m3/h. It seems to do OK with my planer thicknesser (a Perform 10 inch one), provided that I don't try to take lots of wood off a wide board (doubt the thicknesser would cope anyway).

Not sure I'm convinced there's a real need for 6 times more airflow :shock:

Cheers,

Dod

Dod, I used to own the CCNPT P/T myself and found it would happily plane a 10" wide piece of softwood. I didn't really try any hardwoods wider than 6" or 7", but still, you should be fine as long as you restrict yourself to taking off no more than 1mm at a time (and get the grain direction right! :wink: ).

I don't really expect any extractor to perform as well when you're working to the machine's maximum width (10") or planing something down below 1/2" say. It seems to be a little too much for each of the three extractors I've tried.

Although some manufacturers will say different I do not think the drum type is perfect for p/t or stand alone thicknessers, they are hplv (high pressure low volume) and are better for such things like sanders, routers, bandsaws etc.
As Tony says for a p/t you really should need a LPHV (twin bag type) like Ollys ADE1200.

You can of course use either type the other way around but they are not perfect, and if you are going to use the twin bag type I would recommend getting a fine filter and fit it on top instead of the cloth bag.

Cheers

OK...
Found one on Rutlands web site 2500m3 /hr........but its a 2hp motor......
When I have bothPT and extractor running will my 13 amp supply keep tripping out?????

It's not the Fox is it ?? :?:

[dicktimber]

Yes it is........

Must be problems with it eh?????
Tell all......

I have looked at the Fox machine before and I think... they mention that it requires a 16a supply, for some reason? That may be the next size up though.

As for whether it'd blow your fuse on a 13a, it really depends on the power of your planer-thicknesser.

I used to have a 2,200w (3hp) P/T and found that I would have to switch that on first before my previous extractor (about 550w) or else, it wouldn't work.

My new P/T's only 1,100w where as my new extractor is slightly less, so, I don't have any more problems.
