    Build Quality and Performance - Sherpa BOX AIR

    When reliability and performance is key, only the highest quality components can be used and this is exactly what the BOX AIR encompasses. The powerful dual head compressor is designed to reach pressures up to 300 PSI which is far more than most users would ever require. Derating the compressor to 150 PSI means it's working below its maximum design capacity and will last. Beware of cheap knock off units running plastic substandard components that simply aren't robust in extreme conditions. Sherpa use the best components to deliver the greatest performance and reliability.

    The Sherpa BOX AIR performs thanks to the dual head air compressor. Air flows are further improved by the incorporation of a 3.8L air receiver tank. The unit runs an automated pressure switch which controls the pressure in the tank to between 120 PSI and 150 PSI. Having this reservoir of pressurised air improves tyre inflation times as the compressor is left to run from start to finish and continues to store compressed air as you move between tyres and other activities.

    BOX AIR Design

    The BOX AIR is contained in an extremely heavy duty, waterproof carry case. This case is easy to pack in your ute, on your roof rack or in the back of your wagon. Lay the BOX AIR out on the sand and you have a stable work platform which houses everything you need for inflation activities. All components fit inside the box easily without complex packing requirements.

Great portable air compressor! Has many uses! Worth the money 💰

Dustin Neighbors
The little box, that Kurt

There’s air compressor rocks. Well worth the money and only four days to ship to California from Australia. Sherpa rocks.

Power in a Box

Received the Box Air compressor within a week of order from the land down under to Texas, which is pretty good. The shipment was all together with just a little rubbing on the face of the pressure gauge (not in the screen area). Unpacked the box and repacked and everything fit with no resistance on the lid when closing. Power right up and was able to start filling a tire within a few minutes. Filled 5-10 PSI up to 39 PSI in under a minute as a test run. Did two tires and there was only a little heat build-up on the two compressors. The fill line will leak a little at the connection point to the Schrader valve as you move the hose around, but nothing to cause a problem. The gauge assembly worked well to deflate the tires and held pressure at the target pressure. Fits in the back of a Bronco with the other gear. All-in-all it looks like a fair product for the price.

Air compressor package.

Conveniently boxed and comes with all the bits. High output and pretty quiet. Would recommend to others.


When ordered this was out of stock but the communication from Sherpa was excellent and received the goods about a week later. The compressor has all the bits and is ready to use. Inflation of the tyres is fast. I'd recommend spending the extra, steer clear of the Harbor freigth junk.
