I am looking at picking up a 33 gal air compressor off CL and was wondering if any of yall were using this model. comments? I believe it is this one: http://www.sears.com/shc/s/p_10153_...& Tools&psid=FROOGLE01&sid=IDx20070921x00003a gracias. I hope to use it to run my tools and to paint. I spent the whole day yesterday working on a few bolts while staring at a broken nail gun compressor...so i am trying not to impulse buy but tools are always needed
The add doesn't show whether this is an oil-less compressor or not but if it doesn't have an oil sump that you have to fill - pass it up for one that has oil. They claim to be maintenance free but they are "throw away" compressors that don't survive under hard use. I have a 3 HP unit that I have to change the oil on but it will last more years than I have had it. Even at 3 HP it is a bit small for continuous use with air tools. I would recommend getting a 5 hp compressor and a larger tank. (mine is 220V)
Don't go by tank size, it's nice to have a lot of air on hand,but cfm is what gets the job done... I have a 26 gal. 3 hp and my cfm is to low to use a paint gun and my DA runs out of breath real quick... the cfm on mine is 5 to 8 The 60gal 220 volt units are a good home unit. I've seen some with 8 to 15 cfm for around 500 bucks... Just read the cfm requirements on the air tools you will use the most,and buy accordingly...
thank for all the input guys. the compressor is oil-less and the one that just broke on me was as well but it was a nail gun compressor with some leaks. I am hoping to buy this to help finish my car and then sell it before I go away for school as I would have kno where to store it. a 220v unit is definitely long term goal. goin to check it out in the morning. what is the cfm needed for painting? oh, and this one is too big and more than i should spend
Most good paint guns use 12cfm and up at about 40psi... Eastwood I think has a good low pressure high volume gun that runs on about 5 to 8 cfm $159 bucks with two tips one for primer and one for base/clear....
When I get my check from my new job, I'll snatch it up and let you know how it shoots. I should be ready to paint some suspension stuff by then. I was shopping around and the compressor I'm looking at is a deal and has good specs compared to similar compressors. Yay to more tools! oh on the compressor/paint subject... do yall use separators like these or something different .
I made my own 1/2 gallon separator and it catches everything. I got tired of clearing the water out of my tools and hoses.
The pictures wouldn't show much - it is a 6 x 6 inch piece of square steel tube. The part that removes the water is on the inside. I welded a tube on the inside that takes air from the compressor, restricts it and then opens it up at the bottom of the column. Baffles welded in between the top output port and the outlet of the internal tube do a great job of trapping water. Just drain it at the end of each day and I no longer have to deal with water in the lines. I also drain the compressor once a week to keep the water level in it as low as possible. If you like I can draw it out and then scan it in as a Jpeg and post it.
One thing to consider when buying a compressor is the noise level. The Craftsman oilless compressors run at 97-99 db. Rather loud to put it nicely. Also, the one you are considering is the one I got rid of recently. I could run a DA for about 1.5 to 2 minutes before having to stop and let the compressor catch up again. This is a very light use compressor. I picked up an 80 gallon two stage oiled compressor will 14 cfm@90 psi at Harbor Freight for a little over $350. It was a return that was missing the filter. $90 off normal price for a $4 air filter. Now I can use anyu of my tools as long as I want to hold the trigger. And I no longer have to use both ear plugs and muffs. (The neighbors stopped calling the housing association on me as well.)
oh yea, I'd really appreciate a drawing. Sounds like something I could manage to make. tis quite loud... the compressor I picked up is not the one in the ad below. it is rated for 2.5 more scfm and has higher HP. I don't know if it is discontinued but its naaace. If it doesn't get the job done, I'll re-craiglist it and opt for a 2 stage lubed model. but as I mentioned I only need this for a short while. fingers crossed on it gettn the job done.
I have one of those, and the others are correct....get a bigger compressor. It won't run a zizz wheel but about 30sec before it is empty, and a paint gun even less. It doesn't flow enough for continuous use. But for general use, it isn't too bad. And yes, it is too loud to be in the same zip code that you are working in.
