[EXT] Re: [RealSTMFC] "Blaster"

I definitely had to upgrade my compressor when I bought a North Coast Engineering grit blaster. Both capacity and flow are important variables.
I too typically grit blast at around 60 PSI, both with baking soda (currently) and AlO2, whether plastic, resin, or brass.
Note that grit can also lose it's ability to "cut" with age so it does need to be replaced occasionally. I just had to do that with my baking soda a couple of months ago.

Paul, which blaster are you using, and which grit ? Steve

Can anyone recommend a "Silent" compressor that has a high output. I live in a condominium and if I use a standard compressor my neighbors are at my door with torches and pitchforks. Bill Pardie Sent from my Verizon, Samsung Galaxy smartphone

I use diving air. It is dry and filtered. Cheap to refill but costly to start up.

I've found I needed 60+ psi and alu oxide grit to get good results on brass, using a Paasche Air Eraser. Soda or lower pressure didn't have enough oomph.

Bill I use a Iwata Hammerhead Shark https://www.madisonartshop.com/haheshaico.html Extremely quiet, same as a refrigerator. It has a ½ gallon air tank and puts out a max of 118lbs and 2.15 cfm. I recently used it to power an 18g brad nailer, with no problems or lack of air doing a home renovation project. I doubt it would handle a larger nail gun in continuous use. I also have a Badger 260 grit blaster http://www.badgerairbrush.com/Badger_260.asp Badger recommends 30psi, but max of 80psi. I have had no problems blasting baking soda. I have not used alum oxide, but don’t think there will be any problem.
While the Hammerhead Shark is the top of the line, Iwata has a line of “Silent” compressors. Sil-air is another brand http://www.silentaire.com/silentaire/sil_air.asp . And of course Badger also sells one http://www.badgerairbrush.com/Compressors.asp

Bill, i have 2 compressors, a Mr Hobby L7 and a Paasche DC600R.
The L7 maxes out around 25 psi, but is very quiet. The Paasche is capable of higher pressures but is noisier - but quieter than some, especially the home Depot type noisemakers. I'd recommend it but don't know if it's "silent". I think a gas tank may be your best bet. Steve

What we need is a Db rating for them at, say, 10 feet.

Years ago I watched a custom painter doing seasonal window painting inside a Dunkin Donuts and the compressor was almost as quiet as a coffee maker... It had no tank.

Wow. I've been in noisier hospital rooms than that! 😁 You could paint on the kitchen table during dinner and no one would even notice. 😂
