If you have been planning a garage renovation to turn the space into a workshop, you are probably looking at all sorts of tools and equipment to set it up. For some of this equipment, like air compressors, you will have some choices to make. It can be difficult to understand all of the available options when you don't really know what they are, what they do, or what the differences are. Here's a look at some of what you need to know in order to choose the right air compressor for your new workshop.
What Are The Main Options To Choose From?
There are two primary types of air compressors that you need to choose from; you'll either want a single-stage or two-stage air compressor, and the right choice will entirely depend on what you will be using it for and how much compression you actually need.
What Is The Difference Between The Compressors?
You might wonder, apart from the name, what the difference is between single and two-stage compressors. The difference is essentially in how many times the air is compressed. As the name suggests, a single-stage compressor only compresses the air once before releasing it. The air is drawn into the compressor and into a compression cylinder. The piston in that cylinder then compresses the air in a single movement, so that it is compressed to the rating listed on the unit. The air is then shifted into the storage compartment to be sent through the tubing when you need to use it.
A two-stage compressor, on the other hand, will compress the air a second time before it is released through the outlet tube. After the first piston compression, the air is sent into a smaller cylinder for tighter compression. The piston in there compresses the air a second time, creating far more density in the air than you get in a single-stage unit. After the second compression, the air is cooled before it is sent to the storage compartment.
When Do You Need Two-Stage Versus Single-Stage Compression?
In most household workshop applications, a single-stage direct drive air compressor is sufficient. The pressure behind that compressed air is typically enough to run most standard pneumatic tools. However, if you are planning on doing automotive work, there are some tools, such as pneumatic lug wrenches and torque wrenches, that will require more compression than a single-stage compressor can provide.
Either way, the best way to know what you need for a compressor is to see what your tools are rated for. Purchase your compressor according to the rating on your tools and you will always have sufficient air for what you need. Don't over-pressurize, because that can damage the tools and the project you're working on.

Recently we did a home remodel of the bathroom and kitchen. We needed an efficient way to haul away the accumulated debris. Dumpster rental was our practical solution for residential waste removal. Although dumpsters of various sizes were available, we chose the 20-yard model. It measured about 20 feet in length and 42 inches in height. With a capacity to hold a few tons of waste materials, this option suited us fine. We especially liked that the dumpster was delivered to our property and picked up at our specified time. By not having to park the dumpster on the street, we didn't have to worry about acquiring a permit. Less hassle and stress is fine with me. The dumpster rental also included the transfer of recyclables to a recycling facility. Next time you need your trash hauled away, why not consider dumpster rental as a practical solution?
