#12v air compressor portable#
Well, I guess it’s not terribly hard to believe the most expensive portable compressor tested, which featured a twin-head design and a largish external air tank, would be the best performer. These three compressors progress to the next round, which we have dubbed ‘five minutes alone with a 37-inch tyre’.Ĥ2.5psi after five minutes with a temperature of 101☌ĥ6psi after five minutes with a temperature of 107☌Ĥ9.5psi after five minutes with a temperature of If we base the results off the compressor with the fastest time at the fifth tyre, the clear winner in terms of outright speed is the ARB Twin Compressor followed by the Mean Mother Adventurer II and in third place the Ridge Ryder Ultimate. But if you would like to see them tested, drop us a line and let us know! We also decided against including engine-driven compressors such as Endless Air, as these will only fit a certain number of vehicles (making them more of a specialised product). So in fairness to these companies, we will have to wait until they are selling compressors again. The units you see for sale on on-line auctions websites are either grey imports or old stock. Two other companies you might have thought would be included, TMAX and Projecta, are no longer bringing compressors into the country. Stay tuned however, as we will be putting that compressor through its paces once released. Re-engineering a new compressor, which is due for release next year, and have decided to stop pushing their old model until the new unit is ready. There were a few major players who opted out of this compressor comparison.Ī big surprise was Terrain Tamer who declined, however their reasoning was valid. However, our test results did highlight that there in fact varying results when it came to the overall performance of each compressor. It is a bit sad to see, truth be told, that there is a real lack originality in this sector design-wise. This is especially relevant considering there is a fair bit of money separating the cheapest from the most expensive of this design ($140-$319). We were extremely interested in the results of these units, to see if they actually performed similarly or just had an identity crisis.
The offerings from Ironman 4X4, Ridge Ryder, Repco, Tigerz11, Mean Mother Adventurer II and DR Air all on first glance seemed to be twins. One thing we noted was how similar many compressors looked in appearance. The results were extremely interesting, to say the least. We allowed these three top-performing compressors five minutes alone with this huge tyre, to see just how much air pressure they could produce in the set time. This vehicle was also used to power each compressor with the engine running naturally. The test for this was based around inflating a 37-inch tyre (well, 36.4-inch to be accurate) on the Iveco Daily 4X4 we had in the Unsealed 4X4 garage. Once we had assessed the data from each compressor, we picked the three top-performing air compressors, and put them in a three-way shootout. This was, in our opinion, the fairest and most accurate method of testing each compressor. We used the Tyre Dog tyre pressure monitoring system to keep tabs on tyre pressures, as this allowed for accurate pressure readings without having to stop the compressors or take a separate reading (which could have allowed air to escape and in turn provided varying results). To ensure accuracy, we had a second hole drilled in each test rim, with a second tyre valve installed. Speaking of heat, we used an infrared thermometer (heat gun with a laser, basically) to measure how much heat each compressor produced during the test… LOTS as it turns out! It was also interesting to check which part of the compressor was the hottest, and in many cases it was the cylinder head. After all, this is how you would be using these compressors at home! Special interest was paid at the final tyre, which should have taken the longest due to the compressor getting hot. For this reason alone, we thought it was about time to test the top-selling portable air compressors available on the market, and determine which is the most suitable compressor for your needs.Īll compressors were required to inflate five 31-inch tyres (an extremely common size) with each tyre timed for inflation to 30psi, rather than try and break each compressor with a torture test. If you don’t have an air compressor, it must be said a quality unit is something you (as a four wheel driver) will use time and time again, and in reality should be one of the first purchases you make for your vehicle (after a quality recovery kit).
