What type of air compressor do I need to get 110 PSI quickly? It takes forever on my current 4 gallon 135 PSI Craftsman. What is the best bang for the bucks?

Do you just want something to keep in your garage at home? Do you want an oil-free compressor with an air regulator so you can use it to blow out the water lines for winterizing?

Problem is getting it to the 110psi. Once it nears the tank pressure it goes pretty slow. You would want at least 135psi with a big CFM compressor.I got my air horn kit from Amazon. It came with a 2 1/2 gallon 135 psi 12V compressor but the cfm is low. I also plumbed in another 2 1/2 gallon 110V compressor, but I don’t know it’s cfm. I keep my tires at 95 rear and 80 front. It works ok.

Probably need smaller compressor to haul with. Concerned whether it can top off 90-100 PSI,Also looking for moderately priced garage version.

It needs 120VAC power so I need to run the generator or have shore power to use it. It's oil free, so I also use it to blow out the water lines at the end of the season.

a Viair will work for you I paid $160 on Amazon for the basic unit. Yesterday I raised the pressure from 120 to 130 in about 10 minutes. You can spend a lot more if you need all the bells and whistles!
