Will any portable compressor handle 95 psi?

My tires need 95 psi cold pressure. Is there any portable compressor that can handle that pressure in a amount of reasonable time.?

My compressor is ok for 80 psi, but it slows to a crawl when the tire pressure reaches about 85.

(I have a fifth-wheel, but I am posting in class A forum because class A owners have to deal with the problem of higher pressure.)

    I have a constant use 150 psi on board on the TV, works great.

  • The VIAIR portable is the standard! They are not cheap but are excellent.
  • It might be worthwhile to invest on cordless air compressor for our need to check our RV and truck's air pressure from time to time. Like the DeWalt and Makita.

    I myself have no confidence on my RV's China-made tires and will be replacing it on first opportunity.
  • Note from the OP: The CFM 8-gallon 125 psi compressor is an exact duplicate of what I am now using: a Husky 8-gallon 125 psi compressor purchased at Home Depot. Obviously both are made by the same company.
  • What you need to look for is CFM at 90 PSI. Also one with approx.150 PSI max.

    One with 2.5 CFM at 90 PSI or above will inflate a large 22.5 tire without waiting all day to do so.

    If you have adequate battery AH you can use an inverter to power a 120 Volt compressor.

    This is what I went to. The onboard system. Will give you more than you will every need, but just in case I also have a 2000 lb nitrogen 80 lb bottle for emergency back up. The nitrogen system is what I had prior to finding the viair system.

    They also show they have RV system now.
  • Most Class A's have 120 volts available, even at the side of the road. This makes it easier to find a compressor that is large enough to quickly inflate a large tire. Most 12 volt compressors will take a long time to fill a large tire to 95+ psi.
    Harbor Freight has two different 120 volt 3 gallon tank air compressors on sale this month for $39.00 each. One is a 3 gallon pancake type tank and the other is a 3 gallon sausage type tank compressor. If you have 120 volts available, or if you only plan on using it when parked or with a generator, you can't beat the price and either one would probably take care of your needs on an occasional basis.
