Air compressors

[rarebear.nm]

In our 5th I carry a CO2 system that produces 150 PSI at nearly zero noise level. I use that for the tire, air tools, etc. Very fact and quite to top off tires. In the Minnie MH I carry a Viair 450P, 12V with a 100% duty cycle, like others do. The Viair 400 is not rated for 100% duty cycle and may require more time to inflate low tires. IMO if you are going to pop for a Viair might as well pop a little more go for the best. I use to carry an oiless 120v compressor, but it was worthless without 120v power source and was very loud.

You are referring to volume of air. No small compressor can produce large cubic feet per minute. Only a larger cfm compressor can do that. A 5 gallon tank is a little small but does help. A 20 gallon tank would allow all 5 removed before it slows down. Most larger compressors have a much larger tank like a minimum of 35 gallon. The compressor in my garage has a 7 horse dual stage compressor with an 80 gallon tank. I think the cfm of the viair is 2 cfm. I would also caution that the compressor you show is not a real 2 horse power. That’s a 2 horse peak power universal motor. That is probably not rated continuous duty either. That’s a way to trick you into thinking you have a real 2 horse motor. A real 2 horse Baldor or Leeson American made motor draws almost 20 amps continuous close to 30 amp on start up. If you plugged in a real 2 horse motor in a standard 20 amp duplex circuit it would blow the breaker the moment it started. My 3/4 horse baldor driven continuous duty, totally enclosed fan cooled, tile saw will blow a 20 amp breaker if I push too hard on a tile.

With the power of modern battery impact guns I don't bother with an air impact anymore. A compressor for tires and other blowing duties and a good set of battery tools will work great.

I bought one of these from Home Depot for my DP, as I need 105psi for the front:



It fits in a basement storage bin and only takes up a space about 8" wide. There's a 110 outlet right above the bin. I replaced the little regulator with a brass street elbow. That points the quick disconnect toward the front of the tank.

I purchased a Bostic 150psi pancake compressor and have no issues inflating the 110psi tires on our RV. I carry it on long trips to check pressures.
