Default Air compressor info

Hey you guys,
I received as a chrstmas present a “very Good” Home depot gift certificate. I went to the store and looked at this Husky 7.0 peak HP that offers 135 PSI maximum pressure and air delivery 11.7/10.3 SCFM @ 40/90 with a 60 Gal vertical tank. As many of you should know by now, I just work on metal sculptures at a hobby level, and I need the air compressor to operate cutter tools, grinders, and a sandblaster. I have read some tools requirements and most of them are in the neighborhood of 7 to 10 SCFM at 90PSI. However, some time ago somebody told me that many of the information on the compressor labels is not quite reliable. Therefore, my question is should I believe everything I read on the Husky label? If that is the case, is this compressor good enough to operate those tools?
Thank you so much for any info.
Alfredo

From what I understand it wouldn't be a 7.0 HP motor probably made in China.
Is it single or 2 stage?
Get a 2 stage if you can afford it you won't be sorry, you'll probably find more uses for it than you know.

That tank has a fairly large reserve of 60 gal, the actual air capacity on that compressor is probably around 7-8cfm@90psi. Just get rid of the regulator that comes with the tank and replace it with a nice sharpe dryer/regulator. That should be good for most shop operations. The only area that it might fall short of expectations is with sandblasting. Unfortunately to get a compressor that can supply that much air usually costs an arm and leg.

Also, is it an oil-less compressor? If so, they have a shorter lifespan than an oiled compressor. They are also extremely loud.

The short answer is, it depends. I'd be most concerned with the sandblasting. They sell a head conversion to bolt onto a ford small-block that might provide more air than you need for that

"7.0 peak HP" means, if you jam a small animal in the belt, just before your wires melt and your breaker pops, it might, just might draw 22 amps.

The compressor that you are looking at is a twin cylinder single stage, splash lubricated. They brag about 1070, or is it 1020 RPM. Not really that slow but certainly better than a direct drive unit. As a comparison, a commercial unit would run at 500-750 RPM. RPM=noise and reduced life but not probably for your intended use.

Being that the campbell hausfeld marketing weinies are still try to sell with "peak" horsepower, I'd not trust the compressor to put out the CFM stated. Then again, wasn't CH one of the companies involved in that lawsuit for false claims

I'd also suspect the ratings on tools, especially the low priced chinese ones. They seem to draw alot more air than claimed.

Back to the "peak" HP. Look at this ad. I know it's harbor freight but look at the rated HP vs. the peak further down and also look at the CFM. There really is no beating HP when pumping air.

Alfredo, without looking at the machine itself, I'd say it will probably deliver around 6 honest cfm@90psi.
That said, there are more important questions about the compressor.
Is it belt driven, and if so, how fast does the compressor itself turn?
Direct drive compressors can be forced to deliver a lot of CFM, but have a short life span.
2 stage is definitely superior to single stage, and will live a lot longer.
What material is the compressor itself, if not cast iron, does it have a sleve?

Headnut is telling right, Alfredo. I believe the one you were looking at is this one:
Store SKU# 710098 Husky Model VT6314
(If I try to copy their website links I get those crappy 4-line things that usually don't work), but that is the 60 gallon belt-drive unit that matches your specs. Yes, they are lying about the motor by using that song & dance about "peak horsepower" when it is probably a 2 hp 220 volt Chinese motor. It is adequate to turn the compressor & this is not a bad unit by today's box store standards. It is not a professional grade by any means but would probably give good service to most home shops. Notice it is rated at 5000 hours service, 3 year warranty.

If you can possibly swing it, the next step up is a true 2 stage 80 gallon unit that will do what you need.
Store SKU# 746892 Husky Model HS7810
Although the motor has the same description, the pump is a major difference.
Unfortunately, it also costs $420 more, but it is quite a bit more machine and can deliver the quantity of air you need. They say it is rated for 10,000 hours. Oddly, they do not advertise the warranty life, saying instead to call their Internet Customer Service Center at 1-800-430-3376 for warranty information.

You probably need to be sure that you have an adequate power source for either one of these, Alfredo. Find out how many amps those motors draw & also be sure you can deal with the weight, especially the 80 gallon model.
I wish you lived closer; we could find you a old sweetheart like Headnut's but if wishes were fishes the whole world would smell like a dead fish, wouldn't it?
