How to get the most out of small compressor?

I have a small compressor (2HP Sears) that I need to optimize. How about somebody doing compressors 101? I'll look for existing coverage of the topic at work tomorrow.

I've always has a long hose on it. I'm guessing 30-40 ft. Would shortening this to 20 ft do much for me? What role does hose diameter play?...

Thanks,

Keith

A quick search will tell you everthing you wanted to know about compressors and a few things you didn't. A shorter hose with a larger diameter will improve you air flow. The downside is that a small compressor like yours is really suited to pumping tires and blowing off the bench.

I guess limiting the amount of quick connects/un-needed items within the air path is the first thing. I used to have a portable air compressor that had a quick connect coupler off the tank, later on did I realize that this was a bottleneck. I ended up getting a few of these adapter thingies (I dont know the name), its very handy as the hose ends dont swivel, but with this you just use two wrenches and its off. I also ended up drilling the opening bigger (unsure if this makes any diff) (FIRST IMAGE)

Use 3/8 fittings and couplers instead of the 1/4", if you cant find the 3/8" get some 1/4 HVLP fittings (dont flow as much as a 3/8" but more then a standard 1/4"). I later made an adapter so I could use my air tools at by friends places, ect.. incase they are running regular 1/4".
Read this thread as its been covered before



1/4"
Type M: Milton 727 = 0.197
Type I/M: Campbell Hausfeld = 0.191
Type M: No Name = 0.188
Type M: Milton HVLP = 0.275

3/8"
Type G: Amflo CP7 (True-flate) = 0.295

Now the swivel end (dunno the correct name) comes in handy as you can pretty much move/twist the tool wherever you need however its small openings are terrible. I took mine apart and drilled out the openings to as large as possible, still restricts air but at least it flows about 2x as much.

Thanks Bone-I know your probably right but I'll get
good primer out of this one way or another-Have
done it before-but not with epoxy primer..Just have to
try to maximize what I have. Thanks.


Mike very helpful..Thanks..Appreciate it.

I have read some of the existing Knowledge Base threads. Looks like hard piping with 3/4 or 1" would help considerably.
