Author Message   Greg P. (Gparrish) Posted on Tuesday, December 31, 2002 - 09:29 am:    While I know Axel has a thread going, I didn't want to mix this one in. Last night at Lowes I saw a small air compressor on a Two (2) gallon tank. It was badged DELTA, although I don't know if they make it or not. It claims 100cfm, but I'm not sure what horse power the motor was. The setup was very light and probably only about 25 lbs., and the plate on the side indicated 2.2 amp draw at 120 volts. The unit was $99.00. Does anyone have one of these with experience? Seems like a perfect unit for tossing in the truck on an inverter for tire refill. Not sure if it would do much on air tools given the motor size and tank size, but in a pinch it might help. The foot print of the unit was not much bigger than a mens size 12 shoe box. Thanks for any insight.   Paul D. Morgan (V22guy) Posted on Tuesday, December 31, 2002 - 09:39 am:    Hey Greg, If you are thinking trail use, then keep it simple. Check out: http://www.expeditionexchange.com/powertank/index.htm By going with a tank, you are not taxing your altenator with an additional load, and you don't have to worry about something going wrong with another motor. Now, if you are looking for a garage unit, then go as big and as powerful as you can afford. I was looking at compressors last night at Lowes as well.

(Gparrish) Posted on Tuesday, December 31, 2002 - 10:04 am:    Rob, it may only do 10cfm, but it advertises 100cfm. gp   Greg P. (Gparrish) Posted on Tuesday, December 31, 2002 - 10:17 am:    Delta 2 Gallon Home/Hobby Compressor with Inflation Kit Item #: 104810 Model: CP200 $99.00 Oil Required: No Max Pressure: 100 psi Tank Capacity: 2 gallon Supports uses for blowing, inflating, fastening tools, and detail spray gun Pressure switch for start/stop operation Includes 25' coil hose and 5 piece inflation kit Single cylinder 120 volts Cut-out at 100 psi Cut-in at 75 psi One year warranty   Leslie N. Bright (Leslie) Posted on Tuesday, December 31, 2002 - 10:33 am:    100 psi does NOT equal 100 cfm....... -L   Greg P. (Gparrish) Posted on Tuesday, December 31, 2002 - 11:00 am:    Ah, yeah, I guess in a fit of optimism, my brain was reading that as what I wanted it to say. Ooops. silly me................ Well, it looked promising for a moment. Thanks for pointing that out Leslie.   Max Thomason (Lrmax) Posted on Tuesday, December 31, 2002 - 11:06 am:    Greg, that would be sweet! Less expensive than a Quickair or something like that. Its even got a tank! How heavy is the little bugger? Max T.   Greg P. (Gparrish) Posted on Tuesday, December 31, 2002 - 11:16 am:    Max, see first post. "The setup was very light and probably only about 25 lbs., and the plate on the side indicated 2.2 amp draw at 120 volts. The unit was $99.00." gp Would only need a small inverter too at 2.2 amps.   Max Thomason (Lrmax) Posted on Tuesday, December 31, 2002 - 02:22 pm:    Sorry Greg, that little bit just went right over my head. Yea, a small inverter and that rig would be nice. I just might go check it out at Lowes.   Carter Simcoe (Carter) Posted on Tuesday, December 31, 2002 - 03:48 pm:    I'm looking for some sort of air system to, power tank would be cool but I can't really afford to spend that much and I don't like the fact that the CO2 leaks out over time. Someone w/ more electronics knowlege please point me towards how big of an inverter this thing would need to run.   John Friederich Posted on Tuesday, December 31, 2002 - 04:05 pm:    Amps (2.2) X Volts (115) = Watts (253) I've seen a 500 W. inverter at Sams Club for $30 or so. -jsf   Erik G. Burrows (Erik) Posted on Tuesday, December 31, 2002 - 04:29 pm:    The running amperage rating of this compressor, above listed to be 2.2 amps, is the running current, not the starting curent, which is probably 5+ amps, so a 300 watt inverter would give it's all for about 1/10th of a second, and give up, or release the magic smoke. To run this compressor in your truck you would need an inverter rated at at least 600 watts. It'd be less expensive to replace the 120 volt, AC motor with a 12 volt DC motor. Either way, you'd need to run a 30 amp circuit to run it!   Curtis N (Curtis) Posted on Wednesday, January 01, 2003 - 12:52 am:    I'm with Eric on this one, but I would say it could maybe be done on a 15 to 20 AMP circuit if you were lucky. The problem is that this is one of those "oil-less" compressors that uses synthetic rings. They heat up with use and cause more resistance. I bet the 2.2 AMP's is cold. When it gets hot expect 5+. Then add starting the motor hot after a cycle and you are in trouble. If it could be done...it would have been done by now Happy New Year, Curtis   Erik G. Burrows (Erik) Posted on Wednesday, January 01, 2003 - 05:50 am:    Also, the starting current on a near-full tank would be much higher than starting a fill on an empty tank, simply due to the added resistance on the compressor.
