I was recently out shopping for a gas air compressor that I can give my husband for Christmas. He's the do-it-yourself type of guy and since tools was his passion, I've made a pledge to give as much tools as I can, whenever I can. I was confused with a lot of things when I went around our local home revising store.
It was not because of the different brands, but because of the terminologies that the sales clerk were mentioning to me. There were Cfm and Psi, singular stage and two stage compressors, different phase galvanic motors; all was a blur. Finally, I decided to leave without purchasing anything yet and did my own research. I wanted to understand gas compressors and all I needed was my laptop and internet connection.
Here are some of the things that I learned straight through my research:
Psi - This stands for Pounds per square Inch. It tells you how much pressure or compressed gas can be delivered by the gas air compressor. So before you buy gas air compressors, it is requisite that you check the Psi or pressure that your tools require, and make sure that your gas compressor will be able to fit this requirement. If you have multiple tools, think the one that has the highest Psi requirement.
Cfm - an abbreviation for Cubic Feet per Minute. This is the volume of the air that the gas compressor delivers. The higher the Cfm, the longer it will take before the gas compressor recharges.
Single Stage Compressor - This type of gas air compressor has one or more air cylinders. Having more than one cylinder implies that the cylinders are both of the same size. One thing that you should note about singular stage compressors is that you cannot use it on tools that require more than 100 Psi unless you use the tool intermittently.
Two Stage Compressor - this singular gas compressor has at least two cylinders with one being smaller than the other. These air compressors can be used for tools that require higher pressure as it usually operates on 175 Psi. This is more ideal for heavier duty or more pro use.
These are basic terms that I needed to advise myself with. Backed up with my new knowledge on compressors and how my husband will use his air compressor, I set out once again to our local home revising store and bought my husband his first Ingersoll Rand compressor.
