The Rolair 4090HK17-0001 9.3 CFM Wheeled Gas Compressor is a gas-powered twin tank air compressor for outdoor jobsite air delivery. This is a gas air compressor designed for powering pneumatic tools where corded electric power is not practical or not available. Model Number: 4090HK17-0001. If you need a compressor that can ride in the truck, roll onto the site, and feed air tools without relying on a generator or wall outlet, this is the kind of setup that makes sense.

The numbers are what make it relevant on the job. This unit delivers 9.3 CFM at 90 PSI with a 135 PSI maximum pressure rating, backed by a 5.5 HP Honda engine. That gives you the kind of output contractors look for when they need more than occasional trim duty. It is meant for real work, not just airing up tires or running a pin nailer once in a while.

Rolair pairs that Honda engine with an oil-lubricated single-stage pump and an intercooler to help reduce heat and support longer service life. In plain terms, heat is what beats up compressors, especially on long runs. A pump setup built to manage temperature is a big deal if the compressor is going to live in the back of a truck and earn its keep day after day. The atmospheric unloading system also helps maximize fuel efficiency, which matters when the machine is running off gasoline instead of wall power.

This compressor is built with steel twin side-by-side tanks in a 9-gallon configuration and a wheelbarrow-style layout for portability. It is also a horizontal design, which keeps the package stable when loading, unloading, or moving around uneven ground. At 174 lbs, it is not a featherweight, but that is the tradeoff for a heavier-duty gas compressor with a steel tank platform and a larger engine. This is the kind of unit you choose because you want dependable output and jobsite mobility, not because you need the lightest thing in the store.

Rolair also includes a few practical protections that matter in the real world. The Honda engine is described as easy-starting and includes low-oil shutdown to help prevent overheating damage. That is the sort of feature you appreciate after the compressor has bounced around in a trailer or sat through a long week of site work. The glass oil gauge also makes routine checks quicker, so it is easier to stay ahead of maintenance instead of guessing.

The Rolair 4090HK17-0001 9.3 CFM Wheeled Gas Compressor is best suited for contractors, remodelers, and crews who need portable compressed air outdoors. It fits users who work from trucks, move between sites, or need a pneumatic tool setup where electric compressors are too limiting. If you are shopping for a gas-powered air compressor because your work happens outside and downtime costs money, this model is built around that exact use case.
