So I have a 12gallon vertical 1hp craftsman air compressor however it just doens't have enough volume for me and takes a while to fill up. I just got a HF sandblast cabinet and this thing can't keep up. Searched around my local CL and found this
4hp 25 gallon craftsman air compressor. Looked at it and it worked but was missing the electrical cover. Figured that wasn't a big deal and I can make one or buy one. Talk price with the guy and ended up leaving with it for $100 and then bought his 1/2" airstream impact gun for another $15.
Get it home and open the drain at the bottom. nothing comes out but I hear water splashing around so I take the valve off and can see the hole was blocked. use my screwdriver and out comes some water. Dirty Dirty water. And put my screw driver in there a few more times to work around the hole and it kep coming out black goo. This normal?
Oiless wasn't my first choice but the price was right and I needed 110v. So I find this video online
Same make/model etc, then look at my pic and you can see that mine has been changed around. The pressure switch is different, the regulator, the gauge, the lines etc. (I knew I had to add a gauge and that isn't a big deal)
Looked up sears parts website and the pressure switch is not available anymore. So what can I do? I can I buy a cheap $40 compressor and take the gauge,lines,pressure switch off of it and replace this one? I plan to use this a lot but it just looks like a hack job. What do you recommend or what would you do?
Also anyway to clean out the tank or is all that crap in there normal?
Sorry for making it so long. thanks in advance.
