How We Picked

RV-Air-Compressor-FAQs

If you’re shopping around for a good RV air compressor, you should know what to look for. That is why it pays off to know what factors to consider when picking this device for your RV. Check out the following for certain things we have looked for when reviewing the top picks in this category.

Quality

The overall speed of the air’s delivery to the air compressor matters, and it is one of the measures when it comes to quality. For one, you have to check on the cubic feet per minute. The higher the value the better it is. CFM is one of the ratings to look for because it can indicate more powerful equipment.

The Psi or the pounds per square inch are another thing to look for. It matters because it determines the force wherein it will deliver the air. For an RV, you should be looking around a range between 40 and 80 Psi.

On the other hand, you should also determine the horsepower or HP, which determine that capacity of the mortar that is what is operating the pump. A higher rating also means higher cubic feet per minute.

Power cord and hose length

The longer is the better because it can give you more freedom to inflate the tires of you RV. It also means longer hose and cord length also indicates that the compressor can be used in different situations. The best ones can have as long as 30 feet, but then standard and most models now are only between 18 and 26 inches.

Power cords, in most cases, can have a length ranging from 21 inches to 16 feet. Generally, you should look for a portable RV compressor that has a long cord and hose so that you can have more flexibility when using it.

Size

It matters because it has to do with the functionality of the unit you’re buying. For one, a larger tank also means that it can accommodate more air volume. It is better than a smaller tank that can store much less air volume. You can figure that out based on the gallons that the unit can accommodate.

In this case, you might want to get one that has a higher max air volume in terms of capacity if you would use it often. But then, you still have to make sure that the compressor you’re buying also has a high PSI. When comparing, you might also want to look for one that can be a small tank but has a high Psi so that you can be certain that it can also be recharged continuously. It can also make sure that it has longer operation time.

Weight

Weight has to do with the portability of the unit. That is why you have to find one that is lightweight to prevent any difficulty when carrying it around. The best of them are movable and lightweight, so they are extremely portable. You should also find one that includes a carrying handle, case or bag for better portability.

Nevertheless, you should shop around for one that is movable and portable especially if you are someone that wants to inflate balls, air cushions, pool toys and other things that need inflation aside from the RV tires.

Noise level

When finding the best air compressor for your recreational vehicle, you should also look for one that has a quiet operation. You know how that can be so annoying to use one that is too noisy when trying to monitor the inflation pressure.

That is the exact same reason to compare and look around for a powerful yet quietly operating compressor if you don’t want to deal with much noise. Ideally, you will find models that have a noise level of up to 90 decibels. If possible, find one with a lower decibel measure of lower than 65 decibels.

Operating time

What is the run time of the unit? It is another important factor when choosing a compressor, so you should find out the amount of time that you could use it continuously before it needs shutting down to cool it down. Nevertheless, you should check the maker’s instructions about the length of time to use the unit continuously before it needs cooling down to avoid overheating.

On the other hand, we have featured devices here that can work for up to 40 minutes of continuous operation. If possible, you might also look for one that has a thermal shutoff feature that can protect the compressor from damage.

Q: How to winterize RV with air compressor?

A: If you need to store your vehicle in a place with freezing temperatures, you should winterize the water lines.

This winterization is done by removing the water from the water lines to prevent damage to the pipes, valves and faucets due to the expansion of water that turns to ice. However, you don’t have to blow out this water on the lines with force when you’re using an air compressor to do the winterizing.

You have to remove the remaining water with the air compressor. However, such process won’t be requiring like filing a tire, but it is simpler than that. Ideally, you should use a 20g tire inflator to winterize the rig’s water lines and make them safe from blowing out due to freezing.
