What are the advantages of gas air compressors?
There are several different advantages that a gas air compressor has over an electric model. The first, and perhaps most important advantage is that they are much more powerful. Since they are powered by a gas engine, they can compress air at a much faster rate than an electric model, which is ideal if you are going to be doing a big job, like roofing or running multiple pneumatic tools.
The second big advantage for gas air compressors is how portable they are. Even if you have the longest extension cord known to man, you will eventually come to the end of the line with an electric compressor, which just won’t cut it in certain situations. A gas compressor, on the other hand, can go pretty much anywhere, as long as you have its tank full, that is.
Features to consider while choosing a gas air compressor
The tank capacity, to put it as simply as possible, will tell you how much air your compressor is able to hold at any one time. The larger the tank, the more air it can hold, which means the more tools you can use without the compressor’s engine kicking on. If you are someone who has a big job to do and you are going to be in constant need of tons of air, then you should look for a larger capacity tank.
On the other hand, if you only need a little bit of air at a time, then you can probably get by with a smaller capacity tank. A smaller tank will also be more portable.
Depending on the tools that you are going to be running off of your air compressor, you will need varying levels of pressure. If you want to run lots of tools at the same time, you will need a higher level of pressure than if you only intend to run one tool for little bits at a time.
The pressure is shown as PSI (pounds per square inch). The higher the number, the higher the maximum pressure will be for your compressor. It is usually a good idea to get a compressor that has a higher maximum PSI than you think that you are going to need. That way, you will be covered if you choose to use a larger, more air-gobbling tool in the future.
The type of engine that you get on your compressor is very much up to your personal needs. If you are going to be running your compressor all the time, then you don’t have time to wait around for a weaker engine to get up and running. On the other hand, smaller engines are much cheaper, and if you are only going to be using your compressor occasionally, a smaller engine will probably do the job.
No matter what type of engine you decide upon, you need to make sure that it is well maintained. In some models, particularly larger ones, you will need to use engine oil as a lubricant. Some smaller models have a Teflon lubricant band. While these bands do not last forever, they are much cleaner to deal with than oil.
The free air delivery, FAD for short, is a unit of measure that is associated with pressure. It is the amount of flow that you get from the compressor at whatever pressure you are working in standard conditions. This is usually expressed in CFM (Cubic Feet per Minute).
These two measurements will help you to understand and figure out how long it will take you to power up your compressor, and how long the air should last once it has been compressed. By factoring these numbers in, you can be sure that you get the correct compressor for whatever work you have in mind.
Weight and dimensions
How much your compressor weighs and how much space it takes up is, once again, completely up to you and what you intend to use your compressor for. If you need to complete a job where you are going to be moving from place to place, such as painting, then you should probably go with a more portable model that isn’t quite as large and doesn’t weigh as much.
On the other hand, if you are going to be using your gas compressor in one location and you need a ton of air, as in the case of installing a new roof or running a ton of pneumatic tools, you can go for a heavier, larger model.
Air compressors have a ton of moving parts. Even in the best models, something can, and probably will go wrong. That is why you need to be sure that you get a good warranty. But, please be careful to read the fine print. Some companies will offer what sounds like a great warranty but will hide some sneaky terms that exclude the most vital parts of the machine.
As with any tool, gas-powered air compressors come with some extra features to try and separate them from the rest of the pack. We highly recommend that you look for models with wheels and handles. That way, you can easily move your compressor around your worksite with little to no effort.
