When visiting Airvantage Raymond suggested I get at minimum a 2 HP, twin piston, belt driven, 20 gallon aircompressor for the sanders. The sanders shouldnt run at full power anyways so Im wondering which one I should get. Any suggestions? :shead: Im looking at these 2: Craftsman 26 gal. Air Compressor, 2 hp Wheeled Vertical Tank with Accessory Set - Model 16728 at Sears.com Amazon.com: Coleman Powermate Premium Plus Series, Oil Lubricated Belt Drive, 40 gallon Air Compressor: Home Improvement
The more air you can get the better. The higher SCFM you can get the better. Additionally, I would tell you to NOT get an oil free compressor. They're really really loud. Of the two you have listed, I'd go with the coleman hands down. My dad had a craftsman and sold it after a while for an oiled compressor. I have a friend with a coleman and is quite pleased with it. I personally have an Oiled compressor and am very happy. Hope that helps.
I have an oil free coleman powermate invector compressor. Since I do, I wouldn't even think of running an air tool that requires constant cfm like a sander. I have mine to be my own tire filling air station, drive my nail guns, see sporadic use of an impact wrench & ratchets, and now to use the blowgun to dry the car and engine bay. FMINUS, if you have the means, do it right and get an Ingersoll Rand...just looking at reefer_bob's makes me drool.
Ingersoll does make a sweet cpompressor :thumb: Worst thing you could do is buy a compressor that wont keep up to the demand of the sander. Post up the specs of the sanders as far as flow rates and required air and that will help us find the right one for you.
Agreed. Your Air compressor can NEVER be too big. You'll always find something to use the air on. That's why I got an 80 gallon tank, 5hp, 2 stage. I've had too many compressors that were too small. Sanders, Die Grinders, sand blasters... they all use a TON of air, thus my original reccomendation of the biggest and most SCFM you can. Also, if you're going to use a lot of air, also consider a good dryer.
The sander is the only air tool i have and will use. On the Airvantage it says: Maximum working pressure 6.2 bar 90psig I know when using the sander I wont go past half setting, if only hat 1/4 setting. I need something that can move around.
Single stage compressors can have one or more cylinders, and each cylinder pumps air directly into the tank. Two stage compressors have at least 2 cylinders, and the air is pumped from one cylinder into another and then into the tank.
Just found the perfect one. Its the same one they used for the demo: 2HP, 2 cylinder, 9.6 CFM, 23 gallons
Aye, you need to know what the specs are on your tools, eg., 3.2 scfm @ 40 psi / 5.5 scfm @ 90 psi, and then get something rated similar or higher. Higher if you run more than one tool at the same time as well as continuously. Ginormous tank also FTW! The last thing you want is for the compressor to kick on every 30 sec (I could be exaggerating b/c for mine it's a few of minutes if I've got my blow gun shootin air out @ 90 psi which is totally unnecessary but fun as all get out, LOL) cuz it's loud and annoying. Hmmm, maybe you shouldn't listen to me cuz I want one that's the size of a small elephant so I could provide air tool access in every room of my house.
I think most sanders will run about 8cfm @ 90 psi. I would try and stay well above that for a compressor or it will run all the time,and depending on the duty cycle,could overload the motor.
