Best 20 Gallon Air Compressor - Your Lifesaver In Many Circumstances!
Types of 20-Gallon Air Compressors
Single-Stage
Single stage compressors are the simplest type of air compressor. These are single chamber devices which have a motor that runs continuously to produce a constant supply of compressed air. They are ideal for small scale applications. Their construction makes them compact, simple to install and maintain. But they lack capacity compared to higher pressure compressors. Because these compressors don't have more than one stage, they generate less volume of compressed air at a time. They are cheap and easier to operate, but they do not provide enough power output for larger jobs. If you need more power output, consider using a 2-stage compressor.
Dual-Stage
Double stage air compressors work by compressing gas twice. First, the air is compressed by a piston, which is connected to a cylinder. Then the second stage takes place when the air is again compressed by the same piston. These machines are more expensive than single stage compressors, but offer the advantage of increased capacity. You can get a maximum 10 times increase in the quantity of compressed air. However, these compressors require maintenance and lubrication. And they weigh a lot due to the structure being constructed out of metal and rubber materials. Due to their size and weight, they cannot be used for home projects. Even so, double-stage compressors are a popular choice among commercial users.
