Looking at picking up a new dust extractor for my chasing tool. I don't want to spend silly money but want something that does job well.
Any recommendations?
Cheers.

Is it 110v? I don't own one myself, but have used the Makita one on site with the auto-on socket on the top, brilliant bit of kit that. More aimed at chippies I think but it definitely does the job. (seems the 230v model also has the auto-on functionality now too)

I've got an old fein myself, but the dust seems to go everywhere but down the pipe.
Thanks,I was actually looking at this one. I have 240v chaser but know they also do it in 240v as oppose to 110v.
Is it this one you're used?

Yea, a slightly older one but that’s the beast. How much are new bags for it though? That’s how they getcha.

But it's only got a flow rate of 3.6M3/m, and I don't think that's fast enough for a wall chaser.
That’s 60l/m which other brands seem to use, which is on a par with other brands in this price range.
Obviously you can get ones that will suck you in with the dust but he did say he didn’t want to spend silly money

Okay, lets go lower, that's only a litre a second, and those wall chasers seem to throw out a hell of a lot of dust, way more than on say a mitre saw. I agree that he may not want to spend sily money, but he needs t be aware of the distinctions and limitations of some of the cheaper end.
Any other recommendations then that are sufficient for the job. I'd pay a big more for something that does the job..
I'm getting a bit confused by the arithmetic here!
The link does, indeed, indicate a flow rate of 3.6 m³/min. That is 3,600 litres per minute or 60 litres per second. That sounds incredibly high to me - can that 3.6 m³/min be correct? Do you think that it should perhaps be 3.6 m³/hour? That sounds far more credible - and that is, indeed, 1 litre per second.
Kind Regards, John
Typo on my part. That should have said 60l/s for the Makita.
Sounds perfectly reasonable to me. 1L of air is not really all that much, you inhale/exhale 0.5l of air with every resting breath.

Well I reckon if I get the apprentice jogging on the spot I can get him up to 1litre per second with a hose attached to his mouth although I don't think he's going to be up for it..
Any other recommendations? Need this asap now but don't want to buy the wrong one!
Kids these days are spoiled.
Fair enough.
True, and with typical respiratory rate of 15/min, that means that it would take about 8 minutes to breath (in or out) 60 litres.
Perhaps more to the point, with a maximal forced expiration (breathing out a full lungful of air as hard and fast as one can), for a middle aged person the average flow over the first second is around 3-5 litres/sec with a peak around 7-10 litres/sec. We are therefore talking about machines that can shift air around 10-20 times faster than can a human being. I suppose that, as you say, that's not unreasonable, although it does still rather surprise me.
Kind Regards, John
The world is full of machines which can do things orders of magnitude faster than a human can.
