How to Choose an Off-road Air Compressor?
There are lots of notable brands that manufacture portable off-road air compressors that will perfectly fit for overloading. One such brand is the Australian manufacturer ARB, so you can go for them if you need a high-end compressor.
Another one is the California-based brand called VIAIR, which produces various kinds of solid machines at an affordable price. While Smittynilt brand is one of the best pocket-friendly air compressor producers.
On-Board or Portable
For those who have air lockers or you’re planning to install them, then you should get a large enough off-road air compressor that you would use for tire inflation. This is because whether you choose an onboard or portable air compressor, you need an air locker on your axle.
However, in my opinion, if your vehicle doesn’t have an air locker, then a portable compressor would be more flexible and affordable for you than going through the stress and cost of an onboard unit installation.
The Pounds Per Square Inch (PSI)
You need to check the force of air that the compressor you want to buy can deliver. Note that PSI is very vital for running air tools, but most of the best off-road air compressors reviewed above deliver lots of pressure to inflate SUVs and even truck tires.
The Tire Size
Remember that the air volume needed to inflate a tire would determine a couple of factors about the best off-road air compressor for you. So because of this, you should go for a compressor that’s powerful enough to fill up all your vehicle’s tires.
Though you shouldn’t worry about this because most manufacturers normally recommend the best models for different-sized tires.
The Deflation Mechanism
Putting air into your vehicle’s tires can also take time. Though some off-road air compressor valve chucks usually come with an in-built mechanism to release air from the tire without you standing beside your vehicle holding down the valve stem.
You can still buy one that separately airs tires, even though some tire gauges come with this as well. You can also buy an extra tire gauge that locks open allowing two tires to be deflated at once.
Some of the air compressors that are used in off-roading are usually either 12 or 24-volt models. Note that bigger compressors need higher voltage and also deliver higher airflow and pressure.
So to inflate tires for off-roading, your tire’s size rating happens to be the handiest measure to decide what compressor you should buy. But in case you do not have a tire-size guide, then use the other ratings to choose the compressor suited for your needs.
The Noise Level
You should also consider how noisy the unit is when choosing the best off-road air compressor. You need to do your research and read reviews about the compressor’s noise level that you want to buy.
Note that the noise level an air compressor produces depends on its construction, meaning you have to look out for a well-engineered unit.
Cubic Feet Per Minute (CFM)
You need to know the air volume the compressor can deliver per minute. The CPM is what tells you if the compressor is fast in inflating a tire.
So the unit you want to buy should have a high-enough CFM because this is important for inflating large truck tires. As you know, high CFM compressors as the ability to speed up the inflation of any tire.
Is It Necessary To Buy An Air Compressor Meant For Off-Roading?
Yes, because reducing the pressure in your vehicle’s tire while you drive off-road is one of the easiest methods you can improve traction. You need an air compressor to re-inflate your tires after you leave the trail.
You may not necessarily need to have an air compressor if you’re just starting off-roading, but I recommend you ensure you get it as one of the first pieces of gear you buy.
How Do Off-Road Air Compressors Works?
An off-road air compressor works by re-inflating your tires after airing down while on the trail. Most air compressor makes use of electricity to power the motor which then forces air into your tires.
What’s The Meaning Of PSI?
PSI simply means pounds per square inch. This is what indicates the force of pressure that your air compressor can provide for your tire.
But when it comes to re-inflating tires, note that CFM is more vital than PSI. This is because most off-road air compressors produce adequate PSI to inflate a tire.
So if you’re planning to power air tools or air lockers, then a minimum PSI is what is needed.
So What’s The Duty Cycle On An Air Compressor?
The understanding of how long an air compressor can run before its motor would need to rest is what is called the ‘’Duty Cycle’’. If you’re off-roading, then it is vital to buy a compressor that has these duty cycle features.
The reason is that it is what will allow you to re-inflate all four tires of your vehicle before the compressor needs to rest. So if you don’t, then you’ll be waiting hours with partially inflated tires.
If you’re planning for off-roading, then buying one of the best off-road air compressors is the first thing you should do. There are many benefits to airing down your tires while on rough terrain, and you’ll need a way to re-inflate them.
This is important because even if you have a spare, you may still require repairing and re-inflate a tire. So in whichever way, you’ll still need a compressor.
Even if you can find an air compressor that can fill up your tires slowly, I still recommend you get one of the best off-road air compressors listed above to speed things up for you. This would be a good investment for your off-roading adventure.
