This compressor does a great job at higher pressures

My MH only requires 85 PSI front and rear. My HF compressor goes up to 125 PSI.

I am in the market for a portable air compressor and have been following this thread, along with others. It looks like most people replying here seem to be happy with theirs. The only issue I have is the flow rate (SCFM) of this model is 2; I remember reading somewhere in this forum where the writer said that any SCFM less than 3 would not be that effective...so how critical are these numbers...any problems, or should I bite the bullett and get one?

PSI means nothing if the amount of air flow is low. Just look at those pocket compressors; It would take you forever to fill a large tire. I can't quote numbers, but the higher the SCFM, the better. Along with a higher SCFM, comes a higher price.

I agree for the need for the compressor to supply as much air flow at pressure, as possible. One additional consideration is that the higher the CFM the higher the current draw of the compressor. If I remember right, a 1 HP electric motor pulls about 750 watts. My little compressor is only 1/3 HP and runs well off my 1000 Watt MSW inverter.

DO you have an onboard air compressor? If so, why not use it? Love the extra space I gained not hauling a pancake compressor around with me.

I have this 3 Gallon Sear's Air Compressor in the garage, works well except it's noisy, very noisy and sort of heavy.

I decided to get a 12V one to use with the Air Hitch I have and air up the tires on the truck and trailer and this one was recommended on another forum. I tried it and it works well for my needs.

If that first one was "Oilless(oil less), it would be even noiser and not last as long.
Never buy an oil less compressor of any size. Your neighbors will appreciate it.

I've read good things about Q Industries ones, especially from the off-road groups that have large tires they air up/down.

I have this one installed in my truck so that all I have to do is plug in A/C power and pull the air hose out through the rear door of my truck topper. I can reach all 8 tires. Total weight is 37 Pounds.

I have this one: Portable Air Compressor - 2 HP, 8 Gallon, 125 PSI and separated the tank from the compressor so they would fit on the shelves above the passenger side bays on my Breeze. My 2000 watt Yamaha will not run it. I usually only need to fill the tank once a weekend. I only need it to top off the air in my rail tires. It's also plumbed for my air horns.
