When recommending off-road or DC air compressors, we take five features into account.
We start with the amount of power the air compressor can produce. There are two main characteristics of air compressor power: Cubic Feet per Minute (CFM) and Pounds per Square Inch (PSI). CFM refers to how much air the air compressor can deliver per minute (the volume), while PSI measures the force of the air. These two characteristics work together in a crucial balance to satisfy the needs of your application.
For example, if you’re using a tire inflator or airbrush, then having high pressure is more important than high volume. The opposite is true for paint sprayers, nail guns, and other tools where you need more volume. Finally, both CFM and PSI are determined by the motor’s horsepower, which is another aspect of power we consider, along with the voltage requirements.
Many folks scratch their heads trying to figure out if a particular compressor will work in their space and in their particular air system setup. Versatility describes how adaptable or configurable an air compressor is to different applications and environments.
For DC and off-road air compressors, we first look at weight and portability. You want something that is easy to move where you need it. It's also important to be able to mount the compressor in any direction or have an air hose that can reach difficult spots. After all, when you're out on the road (or off it), you need to adapt to the location. Air filters and other protective features are another clue that the compressor is built to withstand any environment.
We measure efficiency by how well an air compressor can deliver your air needs with minimal downtime and at the lowest cost to you as possible. Compressors that can do both very well rank highly because they perform almost continuously, don’t slow down your performance, and save you money.
One of the key measurements in this is an air compressor’s duty cycle, which represents how long it can operate before needing to cool down or refill the air tank. The higher the duty cycle percentage, the longer it can operate continuously without issue.
For example, an air compressor with a 30% duty cycle will run 30% of the time without needing a break. This is very important for DC air compressors because you may need to quickly fill up your tires, for example, and the compressor needs to last until that's done.
Efficiency can take many forms in an air compressor, so we look at the whole unit to determine what features are in place to help bridge the gap between cost and performance. Motor and pump RPMs, tank-fill time, cooling technology, and other factors are all considered.
Sound level is an increasingly important factor, especially when it comes to traditionally loud piston air compressors. That’s why we reward quieter air compressors with a higher ranking. The best off-road air compressors today are barely louder than the average human conversation.
It’s important to point out that the measurement of loudness in decibels is not standardized across the industry, and different manufacturers may test the loudness of their compressors differently. To combat the discrepancies, we typically consider brands that pledge to test their loudness consistently through organizations like C.A.G.I. or publish their testing standards so we can fairly compare them with other compressors. Of course, the best and most accurate way to know is to listen to as many compressors as we can in person and make determinations on our own.
Taking all the above criteria into account, along with price, leads us to an overall value appraisal for each air compressor recommendation. We don’t go by the “cheapest” air compressor alone because you’re going to get what you pay for, and we prioritize performance and quality. The sweet spot of affordability and performance is what we're after.
DC air compressors convert the electric energy created by your vehicle's battery into kinetic energy that powers the compressor pump. As a result, they only work when connected to a 12-volt or 24-volt battery. In most cases, you'll connect the compressor directly to the battery terminals using cables. However, some 12-volt compressors can connect to the battery via the car's cigarette lighter. Learn more in our off-road portable air compressor guide.
Tank DC air compressors provide higher and more consistent airflow thanks to always having air on reserve in their tank. For this reason, tank compressors don't have to start as often and are best for longer, heavier-duty use.
Tankless air compressors need to start more frequently to provide airflow because they don't have any air on reserve. This makes them better for short bursts of usage. One major benefit of tankless models is they are lighter and more portable. If you only plan to use the compressor intermittently, then a tankless will work great.
DC air compressors are most useful for people who enjoy off-roading but are also great for anyone who wants easy access to air power on the road. Whether you're taking a road trip in the wilderness or just around town, a DC compressor will help you with tire inflation/deflation. For these consumer applications, you'll want a 12-volt DC air compressor.
For contractors, truck drivers, and other commercial users, DC air compressors can provide necessary air power on off-road job sites. Maybe you're building a road in the New Mexico desert or pressure-washing your client's cabin in northern Minnesota. Being able to convert your vehicle's electrical energy into air power can assist in various scenarios. I've had customers in agriculture, energy production, and even the military use DC air compressors. Typically, a 24-volt DC compressor is best for these applications, although a 12-volt unit may be enough in some situations.
