Smallest air compressor for walnut blast?
Ok so i think i need a walnut blast. My gas mileage is tanking.
I am thinking of getting the harbor freight media blaster. Right now i have a small air compressor maybe like 3 gallons. Could i use it to walnut blast? I don’t mind having to wait for it to power up. I ask. Bc space is getting limited for me and i rarely have a need for a large air compressor. |

I bought a 6 gallon based on the requirements for the media blaster. Harbor freight has a portable media blaster that needs 4 cfm at 40 psi...then I found a 6 gallon Briggs and Stratton pancake compressor that can supply 4.5 cfm at 40 psi. I haven’t tried it yet...waiting for the weather to get nicer...

3 gallons will not be enough. I would just do it by hand or pay someone else for that hassle. You'll get like 10 seconds of airflow before you're out.
I used a 26 gallon compressor and it was adequate, but not with a lot of margin. There was still definitely time spent waiting for the tank to re-fill. |

I bought this 20 Gal https://www.homedepot.com/p/Husky-20...201H/206189626
Does it take 175 psi for wallnut blasting ? No. Wallnut blasting only needs about 60–90 PSI to work effectively. So its important to have a regulator to set the amount of usable and adequate PSI. This will help the tank last longer and fill quicker instead of running at max psi. Last edited by BaaQaf; 01-29-2019 at 08:14 PM.. |

I've been researching the heck out of air compressors, none are going to be perfect for me now b/c I don't have 240v in the garage.
I'm thinking of these - any advice? https://www.lowes.com/pd/Kobalt-20-G...sor/1000578469 https://www.lowes.com/pd/Kobalt-QUIE...sor/1000405189 https://www.walmart.com/ip/Campbell-...essor/51495094 My other questions are:
Any other tips or pitfalls to watch out for? |

I usd a 30 gallon and it was barely enough. Did something like 3.7cfm at 90 psi. Lots of waiting for it to fill bfore the next blast.

I've used the my new Dewalt for walnut blast too. No issues what so ever. You can probably get a good deal on the Dewalt 15 gallon compressor for under $375.00 right now. I almost bought that one, but opted for the small one due to space saving. https://www.homedepot.com/p/DEWALT-1...5168/302918678 Either one, will have more them enough power to walnut blast or do a brake fluid flush via Mitivac. |

1) gallons 2) CFM - the higher the better 3) max tank pressure 4) space in your garage 5) jobs you are using It for predominantly & how often. 6) ROI & initial cost $$$$ The only job that I can think of where you would want a 30 gallon tank, 200psi tank pressure & a really high CFM would be to clear your sprinkler system lines in the fall. Even then, with a really good 30 gallon tank, it would take a long time to do this job. Honestly, You are better off just paying the local guy $60.00 to do it. He's got a huge, industrial tank in his creeper van or in the back of his pickup truck. |

Or you could price out each piece Individually and probably buy everything for around $175.00 or so which would get you the aluminum cylinder adapter in that price point. Google is your friend. |

Ok well w/ the air compressor I probably want to buy once cry once. I don't want more than i need. Everyone says ignore PSI .. but it makes sense a 200PSI tank will last twice as long at 90 PSI than a 100PSI tank theoretically right?
As far as CFM .. I'm limited to 120v outlet, so 6CFM seems to be the max i can get, 4 seems pretty common, how big a of a difference is 4 vs 6? I have no idea... All I really care about is probably sound, and refill time, ideally i'd like a fast filling quiet air compressor. For jobs? I'm going to walnut blast, besides that MAYBE use air tools down the road when working on my car but that's it. I just really don't want to buy a compressor and realize it falls short and have to rebuy one. And at this point I don't know what I don't know. The dewalts seem very nice. |

Dewalt D55146 - $299.00 - Lowe's 5.0 SCFM at 90 PSI / 200 psi 78 dBa operational noise If you have room in your garage, and you really want more air capacity, then get the DeWalt 15 gallon at Home Depot for $349.00 Dewalt D55168 - $349.00 - Home Depot 5.4 CFM at 90 PSI / 225 psi 78 dBA operational noise The 15 gallon will run considerably longer with out having to refill. The smaller 4 gallon can can run a bit without having to fill up, but quickly recharges and can hold 90psi easily while recharging. |

If you want an awesome Airtool that you would use to get suspension parts off like frozen nuts on control arms get Dewalt - DWMT70773L Just make sure you get a "QUALITY" hose & fittings. Don't skimp on those items... https://www.googleadservices.com/pag...R4Q0Qx6BAgNEAE |
