Air Cube 1
This compressor is a contractor's dream. It can easily power up to three nail* (see note below) guns simultaneously with the 5.4 CFM @ 100 PSI air delivery. The higher pressure and flow allows running longer hoses.

The unit weighing in at approximately seventy pounds can be easily moved, but I usually keep it locked on the truck and run hoses to the work area. The unit portability allows using tools like nail guns, impact wrenches, ratchets, sanders, drills, cutters and spray-painting in remote locations. This 1-1/2 foot cube gas compressor fits in the trunk of a midsize vehicle. The unit can be lifted using the well-placed handle on top. The weight is equally distributed. This is the only gas power compressor that I have worked with that a single average size person can move (alone).

The 4 HP Honda engine is efficient and can operate a workday on one tank of gas. The engine optimizes fuel efficiency by automatically slowing to an ideal speed when the air tanks are full. The engine has three operator controls: on/off, choke and fuel shut-off. The engine usually starts with one or two pulls. The fuel line should be shutoff before turning off the engine to ensure an easy startup. Like most Honda engines, the engine has a low oil shutoff sensor.

The engine, even while operating faster to fill the air tanks, is relatively quiet allowing a normal conversation a few feet away. The engine has a noise-reducing muffler built in. It is quieter than the pancake compressors I have used. The base has four pads to absorb vibration and further reduce noise.

Each air tank has a separate moisture drain valve to keep the tanks from rusting on the inside.

The unit is well painted with a durable paint that is standing up well to the daily abuse of our construction site.

The best feature of all is, no more electrical extension cords, no worries about breaker amperage ratings and no more length of wire power drop concerns.

* The air regulator comes with two 1/4" female NPT thread connections. One of the connections has a hex plug. When I tried to remove the plug to add a hose coupler with an Allen wrench I stripped the head. The plug has some type of thread glue to lock it in place and keep it from vibrating off. Since I could not remove the stripped hex plug, I used the air gage connection to add a tee. Husky (Home Depot) has a brass tee, skew number 661-219 for this purpose.
