Compressor question

[CRittaler]

If you are going to use both tanks as storage then you have to limit the PSI to the lowest safety valve and that would most likely be on the 125 PSI set up.

Also note the safety should release at or more CFM than the pump can put out.

If the pump puts out say 20 CFM and the safety only 15 CFM the tank will still keep taking on PSI till it blows up and that is not fun when it happens!

I dont think I would use the "oil less" pump to fill the 60 gallon tank as I think the pump will burn up in short order. I would use the pump on the 60 gallon take as it is oil type just set it up with the right belt set up.

Being you think the set up was put together from parts because of the belt set up maybe that pump can run at the high motor RPM of the smaller tank setup?

I have a few air compressor part sites saved some were if you need them let me know and I will try and find them.

I would be limited to 125psi which is fine.

Thankfully all my compressors are oil bath type.

I know this pro air system was scabbed together. It was supposed to have a 6.5hp oil less compressor.

My plan is to replace the bearings on the motor and see how it runs as is. I don't expect the 1/2hp motor it came with to fill the tank quickly, but it would be good to see. I also have no idea what the cfm of the pump head on it is.

I do plan on taking apart the outlet plumbing and cleaning it up some.

The bearings arrived and I was able to spend some time changing them out on the motor.

Took the motor apart and man was it dirty.

Also it turns out that it was wired for 220V, even though it had a 115V 15A plug on it.

I cleaned it out and swapped in the new bearings and rewired it for 115V, then put it back together and hooked it back up.

Initial run built very little pressure which I narrowed down to the reed valves being stuck and a leaky bleed off valve.

Once I had that freed up and plugged off I ran it again and found the pressure gauge was faulty as it was slowly building pressure but not indicating such. Once I replaced the gauge and drained the tank I found that this compressor head was quite tired. It took 26 minutes to fill from empty to 125psi.

I ended up taking everything off of my Craftsman 20 gallon and swapping it onto this tank. Now it takes ~7.5 minutes to fill from empty and I have a spare 1/2 HP motor.

Looks like you put together a really nice system! Well done!
