Air compressor upgrade
 

I need to upgrade my air compressor, im looking at an upright, 2 stage, 5-7.5 hp (or bigger), 60-80 gal tank, 230 volt single phase and was wondering what brand you guys are running? Will be running air tools, sand blaster, etc.

I bought a 2 stage 60 gallon one at Lowes , it does all I need and more . Less than $1000 out the door .

I have a Saylor-Beall VT-735-80
Nobody listens but I'd suggest a 1725RPM motor. If you check you'll find they're about double the size of 3450RPM ones.

I have been looking at getting a new one with some more cfm for the new shop. Been looking at 6HP 80 gallon 2 stage. So far Ingersol rand and Quincy look like good candidates. So how big a sand blaster are you looking at? They can burn through a lot of air.

My current compressor puts out roughly 10 cfm @ 90psi and the specs on the blaster require 12-13 cfm, doesnt seem like alot of difference but we had the same blaster in the machine shop and a very large compressor to run the shop and had no problems what so ever.

So I would look for a compressor that will give you 15 or 16 cfm at the pressure you need for the blaster. The pipe the shop to carry that volume you need to the blaster.

I bought a new compressor about a year ago. I debated and looked at IR, Quincy, etc. I finally decided on a Champion 7.5HP 80 Gallon 230v 23.9CFM.

I bought it from TP Tools through ebay. Ebay was having a 24 months with 0% interest if you have (or sign up) for paypal credit. It was not the cheapest around, but I love it and am happy with what I bought and I do love the 0% interest.

I use it almost everyday. I don't think it is that loud and I have enough air that I never have to stop working to let the compressor catch up which includes media blasting. The picture at the bottom is the day I received it before I hooked it up.

These are the specs on it:

Features pre-wired magnetic starter and higher amperage motor for long operating hours.

MODEL 8550-70DS SPECS:

7.5 HP, 36 amp motor
2-stage
80-gallon vertical ASME tank
Cast-iron pump, cylinders, crankcase, and head
23.9 cfm @ 125 psi
Maximum air pressure 175 psi
1035 pump RPM
Splash lubrication
230 volt, 1 phase
Mounted & pre-wired magnetic starter
76"H, 33"W, 26-5/8"D, ship wt: 635 lbs
2-year pump/1-year unit warranty (service centers nationwide)

i just scored this here and the box and blaster do good by them self . but the compressor is 16.8cfm @175 psi and it can run out a bit before shut off happens .

blasting or long run air tools like body d/a sanders or air sander boards EAT air up and always want more .

go big or go home i say for a QUALITY unit . and the resale later will pay off if you ever need to sell it .

and fyi i have 3 I.R. units now . and thats just cause its what found me in deals . and the older REAL quality I.R. units have cast in them on the front cover made in the USA . and there more re-buildable than the newer black pumps .

as said 1725 rpm = much more quiet operation unit . and they tend to pull a few less amps over the 3450 rpm units .

here is my units i have built from parts and rubber mounted them to cut down harmonic vibrations .

my big I.R. 2545 pump with 5hp 1725 rpm 220 motor 19.0 cfm @ 175 psi
my little I.R. 234 pump with 5hp 3450 rpm 220 motor 9.0 cfm @ 175 psi used a motor i had on this one .
new to me SUPER clean 2420n5 pump unit ALL factory I.R. 16.8 cfm @175 psi 1725 5hp motor and mag start .
my new build will be getting this 120 gal tank and my 1st compressor parts to make it whole again like it left the factory for the most part . its a factory 2545 unit that was 10hp motor 3phase 480 volt 36 cfm @175 as it left the factory unit some one started to cut it up for scrap .

I love my Quincy QT54. Purchased mine from the local Rural King during a store-wide 20% off sale. One of the best purchases I've ever made as far as my work shop is concerned.
