I need/want an air compressor.
 

I've never bought more than a tire filler, but would like to be able to:

• Regular household uses
• Blow dry parts
• Fill Tires
• Eventually buy/run some air tools like wrenches and cutters
• Maybe run a soda blaster
• Eventually prime/paint cars.

I don't want, and can't waste the space on a compressor that looks like the robot from "Lost in Space", so what smaller compressors would do the trick? Wall mounted or portable are a plus because my garage is really a small Carriage House from 1920!

Any specifics I should look for? Pancake? Pressure? Volume? Features?

Any particularly good brands as far a value for the buck?

Thanks

Your not going to get much out of these small AC. Youl work them to death [fast] with what you want to do. get at least a 60 gal uprite 5 hp. ken ct been there done that.

Re: I need/want an air compressor.
 

Ken is correct. Small compressors wont cut it. To run air tools, like Ken said, you need at least a 60 gal tank and low amp 5 HP. I have a high amp 5 HP 80 gal tank compressor and it barely keeps up with some air tools demand.

Re: I need/want an air compressor.
 

Check with the manufacturers of the air tools and the soda blaster to get requirements for CFM and pressure. These two are probably the biggest users and will push you to the one that looks like the robot from "Lost in Space". Can you build a small outside dog house next to the garage to put it in?

Re: I need/want an air compressor.
 

Everything said is true, but may I suggest an alternative. I faced the same issue, had a 3 HP unit and wanted to paint and run air tools. Thought about it and realized that while I needed a lot of air, for the most part only needed it for a short time. Went to a propane dealer and asked for two 100 pound tanks that were no longer suitable for propane. Took the tanks, mounted them head to head in the rafters on their side. Plumbed the small compressor into the tanks so that I had the 20 gallons of air in the compressor plus the two big propane tanks. Sure, it took half an hour to pump up the tanks, but I could paint long enough to use a paint gun full of paint, and while I was refilling, the little compressor caught up. Worked for me.

Volume, volume, volume can't say enough for it, and for quicker recovery you need a decent size pump. You'll regret buying too small. Been there done that.

Re: I need/want an air compressor.
 

I have a 5hp with an 80 gal tank. So far it's done everything I've needed. I bought it at a tool store for $1000.00.

Re: I need/want an air compressor.
 

Some real good tips here! Another one: DO NOT buy an oil-less compressor! They are noisy, inefficient and wear out way too quickly! Compressors build a lot of heat so the cheaper ones (esp. oil-less) need "off" time to cool down. Continuous use shortens their life.
Also, if you go the propane tank route as mentioned, do not put the tanks on their side! You need to drain them regularly so mount them with a drain valve at the lowest point or they will eventually fill up with water which will get in your air lines at the most inconvenient time plus will rust out the tank.
Putting the compressor outside your garage in a 'doghouse' is a good idea. You can get mufflers to put on the air intake to keep the neighbors happy. Check Grainger's catalog, etc. Don't forget ventilation, maybe even a small exhaust fan or the compressor could overheat with extended use.

I have three compressors, a small home brand 7cfm for tyres and doing my models, a 12cfm sturdy Austalian McMillan for general shed duties and a diesel powered 42cfm with a 200ltr tank for when the whole afternoon sandblasting or other longtime use situations. The 12 just keeps up with spraying a car, it runs about 50% of the time, but does not keep up at all with sandblasting. IWith compressors there's no one size fits all which is why I have three.

Re: I need/want an air compressor.
 

Re the propane tanks on side, I drilled and tapped a 1/8" NPT and put a valve in to drain the condensate. The side of the propane tanks is thick enough to allow for the drill and tap without welding a bushing in.

I have a 7hp Ingersol Rand upright...and when I blasting or running air tools it keeps up with them...bought it from a IR Dealer here in town...the guy that bought it, turn it back in after about 20hrs of use $700.00 I've had it for 6 years one of the best tool's I ever bought!!!...I can sand blast and even run a DA...spend the money...and enjoy the hobby!

Re: I need/want an air compressor.
 

You will see single stage and dual stage. If you can buy the dual stage. IR 5hp dual stage is in my garage and works well even with the blast cabinet. I think it is the most air for the money.

Re: I need/want an air compressor.
 

My friend used an old propane tank for his air compressor. Years later, you could still smell the odor used with propane.

Re: I need/want an air compressor.
 

I agree. I've worn out enough smaller 2 cylinder single stage compressors that I could have bought a very nice 2 stage good upright compressor years ago.

How much does it cost to save money???????????:(

Re: I need/want an air compressor.
 

I have a 5hp Quincy 2 stage vertical tank.(small footprint) I have never run out of air even when bead blasting. As mentioned it is a slow running compressor and will last. I have had it 20 or so years and only changed oil and air filters. Harbor freight or Northern tool is where I bought it on sale. It was drop shipped from the factory.

Buy a good one and it will pay you back for a long time.

Re: I need/want an air compressor.
 

A lot of good advice.... Oiled, 2 Stage, with large storage... All good ideas. Given the area you live in, one thing completely left out was a good filter (for the extra water in the air) and depending on how much you will use tools a good inline oiler. You will want to have a "clean" air line to run painting items and if you find a small dryer worth the money for painting. I have a 6 HP, 60 gal and other than sand blasting does anything I want from Plasma Cutting to air tools and others... most newer LPHV paint guns are working on less pressure and volume. Good advice to go large and not waste your money.

Re: I need/want an air compressor.
 

Roccaas, I had the same idea after I built a new garage, after shopping around the Web and Sears and others. The compressor got bigger and bigger and whent from 120 volt to 240 volt. I gave up, bought a small B&D 12volt/120 AC for the tires and also new ratchets and extensions and started turning wenches the old way. Check out these sites they help you decide how big, how much you need and cost. Good luck!

Re: I need/want an air compressor.
 

I have used the propane tank setup, it took a long time for the propane smell to go away even though I washed out the tanks first.

the first compressor was 1/2 hp with very old Kellog pump, 1/2 hp was all the electric circuit could handle and still keep the lights on, then I got a larger 3 phase compressor, converted it to battery operation with a golf cart motor(2hp), let the charger run at night--12 golf cart batterys, 36V.

If you want to run most any air operated tool for longer than a few min you should have a real compressor (5hp 220v 2 stage, 60-80 gal tank)

If you want pressures under 100-120 lbs a single stage is ok.

When I was visiting China I looked in many garages, one place had a big tank, and a hand tire pump, when he was not fixing a tire he was pumping air.

Re: I need/want an air compressor.
 

I have a Quincy 2-stage verticle compressor set-up with an 80 gallon tank I bought 20 years ago from TP tools, located in Canfield, MO. They are a catalog sales company. I also bought a bead blaster from them at the same time as a package deal. Both have been used almost daily ever since. They have an excellent customer service department. A bead blaster requires constant maineneance and I have ordered parts from them many times. The compresson has required very little attention.

TP Tools offers a number of package deals including free shipping on some items.

Shop compressor is a two stage, 5-hp, 220v, 3-phase Quincy installed in about 1950 by the US Air Force. Was primarily used by USAF to operate the air over oil twin I-beam style 'grease rack', but it is really more than adequate for any and all tasks that have been thrown at it.

As many before have stated BIG is better. By the way the tank is about 120 gal and is mounted up near the ceiling and out of the way, even when lifting a fairly long car. Only downside of tank location is inconvenient reach to drain condensate.
