Has anyone bought and used this compressor just wondering what the justification is in double the price. over the 21 gal.

http://www.harborfreight.com/29-g...61489.html

I guess I am just wondering if the price is justifiable?
I have an older version of that compressor. It's very good. Makes more air, quieter, and goes to a higher pressure (which is the real benefit). Both the 21 and 29 gallon are quite reliable. The 21 gallon compressor only goes to like 120PSI and comes on somewhere around 80 or a little below. This means that if you're using, say, an impact wrench the pressure at the end of your air line will be well below 80psi by the time the compressor actually comes on (due to the pressure drop across the length of the air line) ... super, ridiculously frustrating. The 29 gallon compressor comes on somewhere around the pressure that the 21 gallon model maxes out at and goes up to around 150 - runs an impact wrench wonderfully. You end up with quite a bit more air stored than the 21 gallon, because besides the fact that you have an extra 8 gallons, it's also 1.25x higher pressure. Multiplying times the increased volume, you end up with about 1.73x more air than the 21 gallon model ... although the increase in usable air is even greater. If we define "usable" as "the pressure in the tank is over 80PSI", then the 29 gallon model stores ~2.4x more usable air than the 21 gallon model, and that's not even accounting for the fact that it starts making more air sooner, and that makes it more quickly. Coincidentally (or maybe not), the after-coupon price difference between the two is remarkably close to this at 2.33x ($350 vs $150).

If you're just using it for filling up tires, blowing out dust, and putting in nails, even the 21 gallon is probably overkill. If you are doing mechanical auto work with it, the 21 gallon is barely adequate, but the 29 gallon is very nice. If you're doing work sanding/painting/refinishing, the 29 gallon is barely adequate and you probably want to go bigger.

I did get by with the 21 gallon for quite a while. If I had a stubborn bolt, I'd let out air until it came on, wait for it to shut off, and then hit it with the impact a few times. When the air got too low, I'd repeat the cycle.

One more note, if you live in a northern climate, the 21 gallon compressor will not start in very cold weather (mine was in an unheated garage). I haven't had the opportunity to try the 29 gallon one in cold weather yet (I got it off craigslist this summer), but I suspect that it wont have the same problem.

One final note, the 2.5 HP rating on the 21 gallon model is a flat-out lie. It theoretically draws the same 14 amps as the 29 gallon one, except that the 21 gallon model doesn't actually draw 14 amps -- I measured my (once again) significantly older version. Maybe the new ones are actually 14A, can't say, but either way 14A is 2 HP, not 2.5. Everybody else inflates their HP numbers too, and Harbor Freight is closer to reality than most, but that still doesn't make it OK. The 2HP rating on the 29 gallon compressor is actually correct (it really does draw between 14 and 15A), and its compressor head is also more efficient than the 21 gallon model. 15A is ~1800 watts, which is the maximum for a standard 120V outlet, so the 29 gallon model is as good as you're going to get unless you decide to go 240V. You also probably will not be able to run anything else on the same circuit as the 29 gallon compressor while it's in operation without tripping the breaker.

FYI, they currently have FWP coupons for the blue 27LED light and the magnetic parts holder. I haven't seen either for a while, and they are my favorites FWP's (good till 11/11/15).

Thank you for the complete review. While I see the perks for sure. Just where I am at I see for like another 100 bucks I can get a huge stand up 240V model so if i am thinking about splurging thats the route I will probably hit but I am thinking of getting the 21 gallon cause I am not doing anything major at all. Not full car restores yet lol.

If you're not running any hungry tools like an impact wrench or an air ratchet, you might consider one of the pancake models. The less powerful one is regularly on sale for $40 w/ coupon, and the good one is quite often on sale at $100. The 8 gallon hotdog is also regularly on sale for $100. Hotdog makes more air, good pancake goes to higher pressure, both are probably fine for limited, frustrating use of basic air tools (impact, ratchet, airbrush). Cheap pancake is good for filling tires, putting in nails & quick bursts from an air gun, don't bother trying to run tools on it.. If you intend to run air tools & don't want to go for the 29 gallon, then I'd strongly encourage you to go for a larger 240V model.

I was taking apart the air dam on my wife's car last night with an air ratchet, and as so many times in the past, I was very happy to have the 29 gal.

Thanks yeah if anything just an impact for getting lug nuts loose so a quick shot and wait should be fine. I have thought about the 8 gallon one if i can find it for 100 but then for like 50 more i can get the 21. I have been meaning to get the pancake or small hotdog style to just keep in the house and take it out to the porch to air up tires and what not.

You can adjust the max pressure and the low pressure where the compressor engages with the 21-gallon, if you so desire. Not sure whether or when it will leak if you raise the max pressure though.

Anybody here have experience with the retractable air compressor hoses? I'm looking to get the 50ft rubber hose version, which goes for $90 normally. Anybody ever seen a coupon for it before?

You referring to the one you'd typically hang from the ceiling? If so, they're good but expect to replace the hose after a year or two. The hose is of some really low quality.

Didn't see this ad posted.
I picked up the "Black Friday 3 Day Sale" flyer in store.
Ad says prices good from 11/27-11/29 and on Thanksgiving Day online.
I took pics of it. (Not great quality but hopefully good enough.)
