Spec me a new SILENT air compressor.

[JOGARA]

Moving house and with that I lose my workshop at the bottom of my garden.
Looking for a "silent" air compressor that wont piss next door off.


This looks to be the best priced one at £210 using the "medical style" compressors that is around 1.5HP, https://www.aimtools.co.uk/products/...nt=29551230215


Any other suggestions? This one I linked is about 20% lower CRF but at 70dB instead of 4x louder ar 98-103dB that is fine...

Specifications: 
Power: 1100W/1.5HP 
Frequency: 50Hz 
Voltage: 220V 
Speed: 1400rpm 
Tank Capacity : 50L

Working Pressure :8BAR/ 116psi 
Exhaust volume: 90L/Min/3.cfm 
Air Supply: 135L/Min4.767cfm 
CE Approved. 
Connection size: 1/4" BSP 
Suitable hose:5*8MM 
Gross weight:37.5KG 
It is Oil Free compressor. 
Start instantaneous power: 2520W. 
Dimensions:670×310×710mm

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.
