My cheap air compressor needs replaced. I have heard that "Viair" compressors are very good. Not cheap but good. If you have a Viair or did have one are they worth the money? Or what is your recommendation for a air compressor. Looking for 12 volt and it will stay in RV or pick up Thanks

What power source do you have available? That makes more difference than anything else.I have a monster 12V air compressor, but it's cheaply built compared to a Viair system. Pay close attention to duty cycle.Details on mine here: http://2manytoyz.com/compressor.htmlMy previous Class A had an onboard 5.5KW Onan generator. I used a Dewalt Emglo air compressor to fill tires, run an impact wrench, etc.Either of these compressors would fill RV tires. Someday I'll have my own Viair. Some of my off-road friends have them.

I have several Viair compressors. What are you wanting to do with compressed air? The larger Viair compressors are rated to 100% duty cycle up to 100 psi, above that the duty cycle drops. If running air tools, the compressor will need breaks, if filling tires, not so much. The biggest killer of compressors I have noticed is not violating the duty cycle, but running to small of wires for the load. As voltage drops, the amperage increases, given enough time that eats the windings internal to the compressor.

Cheap or low cost - Quality or Quantity - Your choice Had a Quick Air III for several years before it blew up - it was cheap junk Now have three 12 Volt Viair systems There are several better 12 Volt compressors - check out the Jeep forumsDepends on what you expect from it and for how long That said Viair is good enough for most applicationsThe Viair 12 Volt system I have now in my rig includes a 5 gallon holding tank and is capable of 150psi @100% DC - fills tires - powers air tools - etc.... It gets used almost daily when we are out enjoying the outdoors As said above make sure it is correctly installed

Quite often Harbor Freight has small compressors with a "pancake" tank on sale for $39. It is more than adequate for car and bike tires, etc.It is barely adequate for topping up an 80 PSI truck/RV tire;takes several hits with re-pump time in between.It runs off 110V AC.

Quit using compressors when my expensive Vaiair copy could not inflate a tire. Bought a 135PSI pancake compressor from Lowes when they were on sale for 90 dollars. Works so well, I gave my big compressor away last year.
