:mrgreen: Thanks for that
so its not very noisy at all , I best go and listen to it running
myturn":3uwqf2cx said:I've just installed an Axminster UB-801F for dedicated use with the lathe and one of the reasons I bought it was its quoted "low" noise level (65db).
It still makes what I consider to be a lot of noise, more than my single-motor Camvac HPLV extractor, and to converse with my wife when she brings me tea I have to shout or turn it (the extractor :mrgreen: ) off.
Coupled with the noise from my powered JSP respirator and the Microclene Air Cleaner I would find the noise level very tiring if using the lathe for long periods.
So my next move is to build a housing for it to locate it outside the workshop as I will be leaving it running as long as the lathe is in use.
Somebody must have very noisy washing machines! :lol:
It may just be that a significant amount of noise is caused by air moving through the ducting, possibly setting up vibrations along the way. Try the extractor with no input ducting before going to the trouble and expense building a housing for it. If the noise drops then think about stopping vibrations in the ducting. Damping the walls, of the ducting, may help a lot.myturn":207z5c1c said:I've just installed an Axminster UB-801F for dedicated use with the lathe and one of the reasons I bought it was its quoted "low" noise level (65db).

There is no ducting, the extractor is connected directly to the lathe by 2m of flexible 4" hose.xy mosian":okxrncyy said:It may just be that a significant amount of noise is caused by air moving through the ducting, possibly setting up vibrations along the way.

I would consider the 2m of flexible 4" hose as ducting. No matter, whatever we agree to call it, try the noise with it disconnected.myturn":3lojgjal said:There is no ducting, the extractor is connected directly to the lathe by 2m of flexible 4" hose.xy mosian":3lojgjal said:It may just be that a significant amount of noise is caused by air moving through the ducting, possibly setting up vibrations along the way.

The hose doesn't resonate as ducting would, but I have run the extractor with no hose attached when I first installed it and it is still just as noisy.xy mosian":10nc62vr said:I would consider the 2m of flexible 4" hose as ducting.

Yes I apreciate that the hose will not resonate in the same way as steel, or plastic ducting, both of which will have organ pipe tendancies. Still I feel there is likely to be noise generated as air and air borne particles fly past the ridges of the inside of the tube. But you have done the test and isolated the machine as the culprit. It does seem strange that the noise levels quoted give so much grief, unexpected. Of course further testing might show other sources of the noise, which may not be the motor, however as you say if you isolate the lot then the problem will be eradicated.myturn":2o9irm16 said:The hose doesn't resonate as ducting would, but I have run the extractor with no hose attached when I first installed it and it is still just as noisy.xy mosian":2o9irm16 said:I would consider the 2m of flexible 4" hose as ducting.

The only way to quieten it down will be to house it outside or put it it in a soundproof enclosure in the workshop. The latter will not be practical for me but putting it outside has the added advantage that I can lose the fine filter to further improve performance.
