Spec me a new SILENT air compressor.

[m_c]

It just so happens I was looking at compressors yesterday, as I've just ordered a vacuum table for the mill, and can't bear the thought of listening to the 3hp combined motor/pump rattling away much more. Plus it's now got that much piston leakage it blows the dipstick out once it reaches about 7 bar

I was searching to see if you can get smaller screw compressors that run on single phase, which you can, however you'll need to at least add an extra zero onto the price of the one you've listed, for a 2.2KW one.

It all depends on how much air you require.
I still need to find a suitable calculator to see just how big a compressor I'll need, but I've not got that far yet.


I'm also considering rigging a hydrovane into the existing compressor tank, as I have a 1.5hp tankless one buried somewhere, but not sure if it'll provide enough air.

I saw this one, single phase, but it's still expensive, I'm sure you have seen it too. At 2.2kw maybe still feasible for home use, if you have the dough.

I am looking for something quiet and affordable just for the mist system, something like the first OP link.

I never noticed that screw compressor, but it was the ABAC floor one I was looking at from that same website, as I've at least heard of ABAC, so hopefully spares will be available should they be needed.

I ideally need a vertical tank, unless I build a lean to outside, or stick it up in the rafters. The main reason I was considering a screw, was for the better efficiency and far quieter running, but I'm going to see how I get on with the hydrovane first. Going by the figures (4.3CFM at 10bar), it should provide more than enough air for the vacuum table.

I got the largest Hydrovane that would run on 240 supply(15PUTS)
Free Air Delivery @ 7Bar - l/sec (ft3/min) 4.5 (9.5)
Free Air Delivery @ 10Bar - l/sec (ft3/min) 3.53(7.5)
Literature says quietest air compressors on the market (have had mine since 1986) so might not be the case now.
Don't know where you are locating it but mine is in my shed, too much load to start in really cold weather, if i am desperate to use it i preheat with hot air gun.piston compressor might not have this limitation?

Scroll compressors are quiet. Less than 60dB.

Just an idea.

Seem to be very similar noise wise to screw and vane compressors.
This screw in 2.2kw flavour is listed as 60dB - http://www.fps-compressors.co.uk/fle...mpressors.html
That 2.2KW ABAC screw I mentioned above is listed as 61dB

Although having checked, the hydrovane is the noisiest at 69dB, which is the same as the compressor in the first post.

From the looks of it, the one I linked is the best bet at the price point one is looking at.

I put a RFQ on Alibaba to see if I could pick a couple of the higher powered motors off there but its the weekend...
Going to order the one linked in the OP I think.

Thanks for all the comments and suggestions.
