Another Air Compressor Question -Updated w/ another question

[SurfinCR]

Since this site has been very helpful in the past and ive exhausted my search of google i'm going to look for insight here.

about a year ago i bought a 60 gallon compressor from home depot as the price/size and cfm rating looked like they were what i needed to run the sand blaster that i needed. While it kept up ok with the air i needed it ran very hot and sucked in a ton of moisture which made sand blasting near impossible. so i went out and picked up a second hand refrigerated air drier that i overhauled and moved the compressor from my garage to my basement and plumbed the system to the garage and my shop (only 10 feet of pipe on one side and 20 on the other). this drastically cut down on the amount of water coming through as before i could watch the water come out of the nozzle, but it is still getting very hot and there is still some water coming out of the tool in use.

what i am debating on doing is replacing the motor and pump for one that will put out more cfm and run cooler. However after research this sounds like it may not be the best option. but has anyone done this before here and is it worth the trouble?

i know i could buy a new compressor but that seems to be a more expensive option compared to just replacing the parts and i really dont want to buy a second compressor.

My current usage of the compressor are for impact guns, nail guns, sand blaster and sand blast cabinet, painting, sanding etc. it will likely be just me using it at any time and i only have 1 phase service. i plan on building a larger shop at my next house so i'd like to have something to fit my needs now and in the future.

If your only issue is the water then buy a GOOD QUALITY water trap and make sure you keep it drained. A larger tank would sure help your issue though.

I have my black iron piping running up and down my wall. Basically making big U shapes. At the bottom of each one I put a T and a ball valve pointing down. Then after 3 of those I have about 15-20 feet of pipe running across my garage then it drops down to waist high with another valve. I have a water separate after the tank and another at the end of my garage. When I am blasting I crack each valve barely to let the condensed water out. I haven't had any water problems since all that.

so after a lot of reading and watching compressors spring up dirt cheap here and there i decided its not worth redoing my current one. i've been talking with a guy that has 2 old models that seem to have the specs i need but i cant seem to find much information on if its worth going with. one is a curtis c96 and the other is a westinghouse 3yc both are 2 stage and both have an 80 gallon tank. the westinghouse has the v design and large aftercooler. both i can get the rebuild kits for but i dont know if it would be wise to use these old compressors rather than a newer compressor. i can get ether for under $300 or should i wait for a newer compressor which seem to pop up once a week for 300-600?

Sandblasting requires a lot of CFM. Of course how much depends on the nozzle size. If your compressor is running nonstop when you are blasting, it is going to get fairly hot. If your compressor isn't pumping oil and it dosn't have a hard time getting up to the set cutoff pressure, I wouldn't think it would need a rebuild. You didn't say whether your compressor is a single stage or 2 stage. For what you're doing, you really should have a 2 stage.
