How to Buy an Air Compressor
So you want to buy an air compressor, but don’t know where to start. Here are a few tips on buying an air compressor. The first thing you need to do is decide what type of tools you plan on using. Let’s say you want to do some wood working and want to use a palm sander and a paint sprayer. This is your starting point, now let’s go shopping.
How to Choose an Air Compressor
When you pick up the these tools look on the box. It will tell what it will take to operate this tool. For example a palm sander will say it needs 4.5 cfm at 90 psi to operate. The paint sprayer will say 4.3 cfm at 40 psi.. Now cfm means (cubic feet per minute). Which is more or less the volume of air it will take to operate. PSI means (pressure per square inch). This is how fast the volume of air will come out.
We now know that the air compressor. Has to be able to produce, no less than 4.5 cfm at 90 psi.. That is running one tool at a time. We now know that the air compressor. You get must be able to produce a minimum of 4.5 cfm at 90 psi. Now let’s look at air compressors.
There is a lot of air compressors to choose from that will run the tools you want to use.
Choosing The Size
You now need to look at space, portable or stationary and your budget. Let’s say you decided on portable, so you can use it for other than the shop (fill car tires etc.). The portables come in different Hp and size of storage tank. In a small shop, a 1 1/2 to 2 hp should be fine the larger the better. Now let’s look at the storage tanks. Larger tank hold more air, this allows the compressor to shut down and cool during use. As long as the compressor can produce more than your using. This will increase the life of the air compressor.
The tanks comes in a verity of sizes. I found that the 25 to 30 gal., works well in small shops. The pictures below are what I use now and works good most of the time. But what ever your choice is make sure it can produce at or above the needed cfm and psi. Now the budget, well you have to figure that on your own. I hope this helps.
