Well I finally was fortunate enough to receive money from my wife to purchase an air compressor.It's a used one but seems to me anyway, to be in perfect shape.Apparently hardly any hours on it.
So it's a
Campbell Hausfeld 26 gallon oil bath Serious Duty model not Extreme duty though
!25 max psi I think maybe it's 130
Belt driven by an Emerson motor that can be wired for 220
Presently it's wired for regular wall plug
6.5 cfm @ 40 psi.
5.7 cfm @90 psi.
I haven't used it yet but I have listened to it run up to max pressure and it took about 5min. plus or minus.
Seemed to hold the pressure as well.
Now I need some help and ideas.Do some guy's replace the copper tubing from the pump to the tank with a finned type pipe for better heat dissipation?Thought I saw that somewhere.
The oil in the bottom of the cylinder pump seems to be very clean.
Should I replace it anyway just in case?
When I first listened to it run we drained the tank and along with the air escaping there was some rusty water coming out of the tank drain.A good friend told me that was normal.I'm wondering though if I should run the compressor up to max pressure a few times and drain the tank to get rid of any excess rust in there.
also anything else I could do or should do? I'm all ears
Thanks Fellas

single phase electrical motors are about 55% efficient they make more noise and vibrate more this is because they have only one phase to run on. The motor gets one thump to spin at 0 degrees and by using a different gauge of wire and adding a capacitor the motor gets a second thump but of reduced torque to spin 60 degrees of rotation later and waits until it turns another 120 degrees ( motor has turned a total of 180 degrees ) to get another full thump of torque and gets another second smaller thump another 60 degrees later (240 degrees of rotation).
Three Phase motors are between 90% and 95% efficient, The get three full thumps of torque every 120 degrees of rotation. this makes the motors quieter and smother and more efficient. more efficient = smaller electricity bill.
My opinion is backed up by 14 years of night school and 26 years in the trade.

now all you need to find out is the price of getting three phase connected your house and the outlet in your work shop.
breakers and wire are cheap, labor is the cost. You need to talk to your local electrical contractor. is your switchboard / meter box big enough.
Air compressors and the tool as a combination when compared to an mains wired electrical tool are only about 5% efficient.
An air compressor running an air drill uses 20 times the electricity as a electrical drill plugged into a wall socket.
All this said I own a single phase compressor
I pump up tires, spray paint, etc but most importantly I use compressed air to clean my chainsaw. :msp_smile:
