Silent Compressor enclosure

[Nicks garage]

Following on from my da sander thread and my compressor running more than usual I have had complaints from my one neighbor and my wife about how loud it is so I set about building an enclosure to silence it,

Check out the video and let me know your thoughts

Just my speculation, but I think most of sound may be from the intake where some kind of silencer might make a big difference.

I have an upright oilless of the cheap variety that sounds like an A10 Warthog, meaning I can only use it during middle of day etc.

Is the video working? The inlet was just part of it, the video shows what a massive difference it makes and also the ventilation method

I'm surprised a compressor with a small tank like that is sufficient to keep your DA charged and running full speed.

So it runs non-stop while you're sanding? Did you provide for a drain for the tank? I like the elaborate baffles you made but I also wonder about the heat, I see the letterbox outlet, is the only inlet the one that's also used for the intake air?

Lastly I'm surprised at the small size of the inlet tubes, seems like that wouldn't be enough to keep up with the output needed for a DA.....

All in all, an interesting build and it sure does knock down the sound!

The air inlet is on the front and is fanned, I tested it with a smoke pellet used For testing the draught of a chimney and it clears through,

I’m yet to make the external drain but it is in hand, truth be told I don’t drain it enough so it was the last thing on my mind

As for the pressure for the DA it does run almost continuous but it’s something I will only be using every now and again so I’m not overly concerned

Looks good, other than the cooling concerns..

I will have to wait and see with the cooling but the way I have made it with the 4” pipe connection on the front it wouldn’t be difficult to add an external more powerful fan if I do need it, the exhaust vent is working great. There is much more flow than it looks but again the opening I have made could go bigger

For anyone interested in this project it’s running well but I do need to modify the air intake into its own baffled box because it is getting relatively hot in the box it’s drawing more humid air into the compressor

I have been working on the car and managed to over work my old compressor so have upgraded it to a Clarke industrial with a continuous rated motor and bigger 150 litre receiver, I will also be adding my 100 litre to the circuit because I have just bought a blasting unit,

anyway I decided I wanted the compressor in the garage this time closer to where the blaster will be And this compressor needs a 16 amp socket so I have built a new enclosure
