air compressor and tools

[Mouthfulloflake]

because as you get to larger motors, 220V is more energy efficient, the motor doesn't have to work as hard - therefore it will last longer...and cost less to run it.

thats why and, you CANT get 5hp from 120 volts.

(120 volts) x (20 amps) x ( motor effecniency theoretical 100%)

divided by 746 to find HP

that gives you 3.2 HP with a 100% effecient motor.
most high dollar motors are 92 percent.

220x20x1
divided by 746

gives 5.2HP

220 is BETTER.
and the motor ratings are BS.

whats IR???? ingersol rand???



the compressor Ive been looking at:

26 gallon, vertical, oil bathed, 5 peak HP.....its a little better than what Ive been using all along, so figure I wont miss anything...they want loike 370 for it, and I have a 10% off depot coupon....

they also have:
60 gallon vert, oil bathed, 7 peak but that ones for 220....this one is only like 20 bucks more!!!!!!


my boyz all tell me that the 26/110 will be sufficient......Imjust having trouble with the bigger compressor for same money thing....I guess I just hav to decide how much space I want to give up......My "shop" is a 2 car garage that I do NOT park vehicles in....

here's a pic of each...

Go for the 220v. It will be a great home unit. Price is right.
Wire it from pressure switch right to a 20amp 2 pole breaker. Use your breaker as on'off control. The 60gal tank will help the unit keep up with heavy use (sanding & painting)
As Mouth said the HP rating on home units are very over-rated. Due to the high RPM motors.
Yes, IR is ingersol-rand.

Many (most?) of them are convertable, so for example if you dont have 220 in your garage you can hook up 110 and upgrade the wiring later.
I've been managing with a 110 unit for years. Portabiltiy is nice. Downside,
I can not run grinders and such continuously, you have to work a minute, let the compressor catch up, etc. This is tolerable for ocasional use, but obviously if you do that kind of work every day you should look up the CFM ratings on all your tools and size the compressor to keep up.

oilless comp.

I recently went through the same debate. After comparing the best that Sears had to offer, Home Depot & Lowes, I bought the biggest Lowes had (Kobalt). It has 13.3cfm @ 90psi, 60 Gal and heavy cast iron cylinders. This is pretty quiet for how big it is. It cost me a little more than I was going to spend but after using this with a pressure-fed sand blaster it more than keeps up. I ran and wired 8/3 with a 50amp breaker from the main (220v).

I know you already know this but those oil-less compressors with a so called rated 8hp and 175psi are such crap. Besides, they are sooo damn loud.

I went cheep route and bought the campbel hausfield oilless comp. lasted 1.5 yrs. and never kept up w. right angle grinder, it is loud as he-- too. Try tractor supply if you have one near buy, nice units decent price.

 

[T-bone]

if this is for a home shop , go by sears, i picked up a great 15 gal 150psi that works perfectly, if your using one a bunch go with a bigger tank and belt driven motors will last longer. but like charlie said the direct drive are a little on the loud side. mine's just sitting it the basement right now and i can baerly hear it cut on if im up stairs.

 

[Idok]

ok, well....ended up getting the 60 gal/220 model...............and some husky tools with the lifetime warranty....:cool2:

went to depot with butti and motosurfer......They were going to buy an 80 gal as well....

the look on the guys face was priceless.....

us: "give us one of each"

him: "you mean, you want them BOTH?" :bigeyes:

Back to air tools:

What brands will last and not break the bank?

Husky
Stanley
Ingersoll-Rand
Craftsman
...

 

[Idok]

i'd go with the husky bro......I bought an angle grinder, 3/8 impact, air ratchet..

none of them were over 60 bucks, and all come with lifetime warranty.....


i bought a POS air body saw from harbor freight....which sucks......



one thing I'd like would be an air chisel and a DA

I have 2 air chisels (cheap arse ones) I rarely use them, what you want one for?

If you want something to last forever I would spend the $ on Husky. But no more than they get used on ski and 4 wheeler stuff or rotating tires, I just went to Harbor frt. and bought the cheap ones. Nothing broke in over 2 years.

i woould have LOVED an air chisel to defoam...especially under the rub rails......

also to chop off bolts off trailers etc.....

Cheap at Harbor FRT bro., an air chissel to defoam, I aint looking forward to that. I was hoping a right angle grinder and wirebrush attachment would get it all???

How much did all the old foam weigh?:sneaky:

 

[surfjetlouie]

I have in my shop a 80 gal Porter and Cable that is made by Ingersol in China and I had it rebuilt 2 time under warranty piece of crap. for air tool I have chicago pneu fro Harbor freight and I have been using them for the last 3 yrs they have been under water a few time and my shop there is lost of dust from wood and fiberglass and they still work well they have been drop several time also and forgot to oil them many time so that was the best $59 spend for 3 air tool.

 

[Speedfreak]

With air tools I try to get the plastic boddies tools or tools with a rubber covers around them. Most aluminum bodies tools get cold when you are uning them in the colder months. If you are running a ton of air through them without a water seperator they will get wet inside and get really cold so you have to wear gloves. A water seperator is a must.

And I reccomend the high speed air drill from craftsman for a die grinder plastic boddied and works great uses a regular drill chuck to replace the tools Quick and simple when doing porting work.

Also look at your local pawn shop some times you can get broken tools and have them replaced or rebuilt for a fraction of the money. I bought a blue point 3/8th inpact for $20 that didn't run (I had already checked in to it) Snapon charged $85 to replace it since it was so old. So for $105 I got a new 3/8 impact which retails for $225.

 

[michael950]

The $50 3/8" impact gun is going back today. I bought one b/c I could not remove the bolt in the crack holding on the flywheel. It is rated at only 75 ft-#s of torque!!!!. The cheapie Champion from Sears is rated 250 ft-#s and is currently on sale for $29. The IR 1/2" is rated for 600 ft-lbs (specs).

Needless to say, I could not remove the bolt. It might be my pancake compressor, but I only need the gun to run it in short bursts of 3. Then the compressor kicks on, then another 3. That should have been sufficient.

I ended up using a 3' steel pipe, breaker bar, and propane torch (in case any loctite was used). Was easy.

 

[feartheride]

I think you would be better off with a cutt off wheel on an angle grinder for cutting bolts rather then chisel

 

[WFO Speedracer]

The kobalt tools are actually made by the same company as snap-on tools,also anything that is snapon and says bluepoint on it is made by someone else for snap-on.

 

[WaHoo_1]

Scott, how bout a follow up review? Are you happy with what you ended up getting (60 gal) or would you have done it differently? Any problems with your set-up? Good bad or ugly?
