How loud is your compressor!!!

Rotary air compressor, like a blower to run your air tools. They are not cheap but so quiet and never run out of air.

 

The guy that painted my truck had the compressor that Noah built the Ark with it. It was at least 30 years old back in '87 or so. That sucker was loud!!!

I pity the original poster. I hate a loud compressor.

 

1. If it's a horizontal unit, put rubber isolators under the feet. big vertical units need to be bolted to the floor.
2. Get a muffler for the air intake.

See how much that helps, if it's still too loud then build an enclosure, typically any partiton that incorporates an air gap, or is particularly massive (heavy) will work well. Do a google search for "walls with high STC ratings" STC=Sound Transmission Coefficient. As others above have mentioned, make sure it can get fresh air to the intake, and to cool the compressor head.....

4. If all that wasn't enough, go buy the biggest heaviest, Nicest compressor you can afford.... one that produces the CFM you need at a the lowest RPM.

Good Luck..

 

When I built my detached garage I knew I would be using the 5hp compressor alot for the blast cabinet I use almost every day. Rather than insulation I used sound proof batting material and also did the walls with T111 wood for more protection and can hang crap anywhere without looking for a beam. Never understood the sheetrock in a garage thing as I never saw one that didn't have a hole someplace. I have none. Neighbors are right next door and cant hear any noise but it is a little loud for me inside at times. I just turn up the TV a little more that sits over the blast cabinet when I'm working.

 

Is your compressor one of the "oil less" style? As in no oil in the crank case---it runs on sealed bearings on the crank shaft. I had a 60 gallon craft man oil less unit for a couple of years. Those things run at very high speed and MAN are they noisy!!! Did the padded/sound deadening cage routine, extra rubber padding on the feet---The whole route. You could STILL hear it across the street!!! Finally gave it up and bought a conventional style compressor. AAHHHH, That's better BILL RINALDI

 

Mine is a 60 gallon Speedaire that I bought in '91.Ran the hell out of it for years,always loud,then I grenaded the pump and had to buy a new one,about 5 years ago.New pump from Grainger,and now it's half as loud as it was.Didn't realize how the old pump kept getting louder and louder over the years.Mine is still sitting on the wood pallet that it was delivered on,I figured that would isolate the vibration/noise a little.

 

Check into Garage Journal. In one of the equipment threads, someone mentioned lengthening the intake filter away from the compressor using heater hose. Apparently it works in some applications. Depending on the style of inlet used this may be a cheap fix.

 

Yep, if it's one of the oil-less compressors you're stuck with noise. If it's a traditional compressor, just build a wood and spring sandwich to set it on.

I've got a Heinz 57 upright that has an 80 gallon tank from a Black Max, a Kellogg two-stage compressor built in the 50's, and a large frame 5 HP 240 volt motor. When I first built the shop I had the compressor sitting on three rubber pads between it and the floating concrete slab. My shop has radiant heat in the slab, with a layer of bubble type reflective insulation under it all, so it truly does float. The slab basically turned into a sounding board when the compressor ran, and the rumble was unbearable. So I built a wood and spring sandwich. There is a 3/4 inch plywood sheet bolted to the compressor legs, and another 3/4 inch sheet that sets on the floor. Between the two pieces of plywood are 10 valve springs from a 1946 Cadillac flathead. A 1000% improvement over having it just sit on rubber pads under the feet. Now the compressor does a little dance when it runs, but it is very quiet.

 

i agree i had a quincy, noise as hell. then i picked up a old orange devilibiss and the damn thing is quiet as hell.

 

I have a 220v Snap-On upright that is in the garage and very quiet. The garage is connected to the house and you cannot hear the compressor from inside the house. It cost a little more, but no complaints form the wife!! Priceless!!

 

My buddy built a small shed for his.
Works!
My shop is next..
My dog and I hate the noise.

 

I will never again own one of those noisy ass high speed compressors, ever.

The best way to quiet a compressor is to buy a better one.

Mine is a 7.5 HP 32 cfm that runs pretty quiet at somewhere between 500 and 600 rpm.

Oh yea, turn it off at night, if you blow an air line it will run, and run, and run......

 

I had an old Habah Fleight IR... it was loud... so I bought a Craftsman shaft drive in 1996... it was louder, so I took it back.
Had the IR for years... and then came across an old two stage Swan...

I don't have to wear ear muffs any more.

My son and I built this one for my older son, it is another 7.5 hp unit we made from an old noisy worn out I/R compressor. This one is way quiet, more quiet than the video might make you think.

It was cheap to make with an old "core".

 

the pump and motor does not have to be on the tank, you can remote mount the motor/compressor and keep the tank closer to the work.


also go and complain against the nieghbors ac unit
