Air compressor
« on: November 21, 2014, 05:37:57 AM »

Been too long since I had to buy one of that size for me to say. I've had my Dayton for approx 30 years though with only one repair,a reed plate, in all that time. It has never been turned off for 30 years approximately.It runs every day without fail.

I bought an old one used with a 2 stage Kelloge pump.  It's rated for 150 psi.   Ended up buying a new motor for it even though one it had was just rebuilt. Don't think pump oil had ever been changed, took two hrs for it to burp out. It's outside and quite as a mouse. I run hard lines inside for drops. Usually leave on all time too.

I stole it for $100!!

Most likely last you a life time with proper maintenance and will give you a solid base for future up grades.  Will run a half inch impact but don't expect it to run any air grinders for any length of time.  Docto's and such take twice that amount of air.  They will run for just a short time then lose power.  Later when the pump gives up go to Granger and get a good hi volume pump and put on it.  Something  around 35 or 40 cfms at 90 psi. A good hi volume pump will only reach 120 psi but will supply that psi at a consent out put.  I built most of my compressors using five horse power motors and Granger hi volume pumps.  Still going today and will out perform my new 7.5 screw.  Ran all my CNC mill's with sometimes three or four Docto's going at the same time.

When I was looking to build mine yrs ago, found a place out in midwest I think, called Surplus Center.  They had some big volumn pumps for pretty cheap.  I bought some stuff from them, but freight it to high on heavy things.  But I did get the 5hp elec motor from them.

Don't be mislead by HP claims either. Quality motors will be  HP rated @ FLA(full load amps) 100% duty cycle. Cheap stuff will be HP rated @ motor burn out amps or less than 100% duty cycle. Some as low as 20% or so. BIG ,BIG difference.

 Check/compare the duty cycle of the compressor as well.

The IR unit you posted looks like a pretty good piece. They state 100% continous duty on pump and say "Running HP - 5 HP ". That SHOULD indicate FLA running. That would be good also.

The craftsman is 3.1hp @ 75% duty and the husky is 3.2hp with no duty listed.
