Can you get a

[Blister]

Silent dust extractor / vacuum

or quiet

I want a dedicated unit to work with a scroll saw

Any recommendations ? :wink:

A mate of mine uses a "Henry" with his scroll saw - much quieter than a normal extractor and easy to empty.

But then in your workshop would look a bit daft against that monster roof lifter!! :lol: :lol: :lol:

Get a little hose, small diameter and a T junction. Hook this up to your tap. Put the water on. Take a the bit of hose from the T and it will suck and water will come out of the other side of the T. It will be queit and relaxing. Should do for the minimal dust a scroll saw makes

I would have thought that water would come out of both sides of the 't'. Mind you, that would keep the dust down anyway

What about the cost if you are on a water meter! :shock:

I know that water doesn't come out of both sides. The only reason I know this is that when we were about 12 at school they gave us a smoking demonstration, obviously they couldn't light up, smoke it then show us the filter so they instead did this which sucked the cigarette. One of the more interesting science lessons seen as I remember it.

You could always keep the water and pour it back in at the top.

 

[Jonzjob]

There is one of 2 situations here Chems? Either you are not putting this down in a manner that I can comprehend or I am thick as a brick? Probably the latter, but I an intreigued? Is there any way that you can google your 't' piece so as to give a better description? I ain't being alkward 'onest. Just very interested as to how it works #-o #-o #-o

Water doesn't come out of the T because of the Venturi effect. We used to use this type of suction in the lab on aBüchner funnel. Don't expect much suction though and it's dependent on the flow rate of the water. More info: http://en.wikipedia.org/wiki/Venturi_effect.

This same effect is used to remove protein from fish tanks when keeping tropical salt water fish - a large (ish) pump is used though to create a decent pressure differential so that you can introduce tiny bubbles.

 

[Jonzjob]

A 'T' and a venturie are 2 very different animals WCogs and if a 'T' worked on the same principle as a ventirie tehn I wouldn't get any water in our house because all we would get would be bubbles as the connection is via a 'T' and it goes on then to my workshop.

Thinks? If that is the case, do I have a built in dust extracter? No way... :evil: :evil:

 

[Chems]

It may have been more elobrate than a T then, but thats how I remember it in my mind. Like I said thou, I was 12 and that was I'm afraid quite a while ago now.

It isn't a 90 degree T, more like 135 or 45 depending on which way you are measuring. The water can't go up the line where suction is created.

Sorry for the poor line drawing - ignore the 2 dotted lines. Spaces seem to get removed.

My Festool is not too noisy for it's type, but still not quiet.
Have you considered building a sound-reducing box to go over an extractor, maybe even putting it outside?

 

[Jonzjob]

Dibs that's the same sort of thing tha's used for a water vac for fish tanks.

The bit of lab equipment Chems is refering to is a filter pump item 122 on this site http://www.saiscientific.co.in/misc.php

The water doesn't come out the side - honest. According to some of the marketing on the websites it requires 7.5 psi of water pressure to pull 28.5" of mercury

 

[Blister]

Ok thanks for that

So what pipes are the inlet and outlet ?

Does it require a powerful pump ?

or something like a fish tank pump

I assume you would need to regulate the water flow some how

Has anyone else used this method of dust extraction ?

 

[Recky33]

If you put one of these in a bucket with water in and link it to your scroll saw it should pull quite a bit of air, at least enough to keep fish alive in 110 ltrs and if it doesnt you have only lost £12

I think you're looking for a 'water pump attached to a lab water tap' - have a look halfway down the page on http://talmos.backwellschool.net/vle/Sc ... ration.htm . I used to have a polyethylene plastic version of one of these that I used with a large Buchner funnel to speed up filtration when wine making. The only similar thing I can find is http://www.mrs-scientific.com/item/Labo ... 552_1.html but you may be able to find something similar and cheaper with a bit of searching.

Honestly, I feel like I'm talking to myself sometimes . They are also known as aspirators (http://en.wikipedia.org/wiki/Aspirator).
