Top 6 Best On Board Air Compressor - Review & Buying Guide

In simple words, an air compressor is an electrically operated device that allows atmospheric air to be put into a tank to be used for different devices. This compressed air is used in many places such as for casting in the foundry shop, for applying brakes to rails and vehicles, for spray painting, to fill the air in the wheels of motorcycles, truck buses, etc. It is also used to cool gas turbines and aeroplanes.

Most commonly we see someone who buys an air compressor and says look this will run my half inch impact wrench and then they want to get a big sandblaster. It doesn't work that way right. First of all, you have to ask yourself where you are going to use an air compressor.

Do you want to use it occasionally, such as to fill the air in the tires of your car or do you have a shop in which you want to use it to run air tools? This is very important because some tools consume a lot of air. And the more air they consume, the larger the air tank you will need and the more horsepower you will need and because of which more input voltage you will need to make your compressor run.

In this blog, we're going to talk about what you should look while buying an air compressor and suggest some of the best on board air compressors for you.

Factors To Be Consider While choosing A Best On Board Air Compressor


SCFM

SCFM is one of the important factors that you should consider while buying an air compressor. SCFM means standard cubic feet per minute. So basically it's a volume you're taking cubic feet of air from the atmosphere, and you're compressing that with the pump and storing that in a tank and then utilizing that later for tools or whatever you're using the compressed air for. So it's a volume component of how much flow is the compressor putting into that system.

When you go to buy your first air compressor you're going to say okay is there a number that you want to buy for us CFM's. The number of SCFM depends on a variety of things. So when you're buying a compressor first you need to look at your tools should be rated for the different SCFMs and the different pressure ratings on them to figure out exactly what you want to use.

So ideally when you're out looking for an air compressor look for something with good SCFM numbers.


Tank Size

The bigger that tank is the further you can go. Fundamentally the bigger the tank is, the longer you can use the compressed air before the pump has to kick back on and fill that tank back up again.


Electricity

In most home garage, you have 120-volt outlets throughout that's no problem those are the things powering the light bulbs in your garage. Very few of them have 230 or 240-volt outlets. Those are the kind of things that power your clothes washer, got a washroom your garage you can unplug it and plug in a larger compressor.

You can also have a certified electrician come to your house and rewire outlets in your garage to add more power. Again more power, bigger compressor, better tools you can run


Noise

Noise is a factor that people tend to ignore a lot when buying an air compressor. Nobody likes a noisy device because first, they irritate a lot while doing some work and secondly due to that noise, a lot of power of the device also get wasted. So you should always take a compressor that makes very less noise, and if it does not make noise then it will be even better.


Price

Price is a factor that people pays attention while buying not only the compressor but to buying any device or any product also. As you know the more money you spend, the better you will get. It is better to buy a product of good quality by paying a little more money. But what if you have a limited budget? Then for that, you will have to do some deep research that which compressor has all specifications that you need and is cheap also.

That is why we have included all the Air Compressors for every budget in our best on board air compressor list.
