I know that some will ask, what about mud, dust and water getting in the compressor due to the location where it's mounted? The Outback ExtremeAir compressor is very well-made and tested in some pretty extreme condtions. the compressor uses a 3/4 horsepower fan cooled motor making overheating a non-issue. This unit can fill tires continuously (100% continuous duty cycle) without motor burnout or overheating. With a 150psi working pressure, it can fill air tanks and run impact wrenches. For clean air in the dirtiest environments, the ExtremeAire uses an oversize UNI-Filter that is crush proof, washable and reusable. All major motorcycle teams use UNI-Filters for Baja and motocross racing. In addition, the fan shaft has a sweeper filter to keep dirt and debris out of the motor and brushes, at the same time, allowing moisture and condensation to escape. It also is permanently lubed with sealed bearings so it can be mounted in any position making installation a lot easier. It also utilizes stainless steel fasteners Loctited for long and trouble-free life in the highest vibration applications. the manufacturer (who happens to be a friend of Dwaine's) backs up his product and confidently states that no other 12-volt compressor has the speed, continuous duty cycle, output, pressure rating, and reliability that the ExtremeAire can deliver.
