Two Stage Vs. Single Stage Air Compressor: An Air compressor is a versatile tool for every workshop that can provide a wide range of applications. You can find different types, sizes, and shapes of air compressors on the market. However, most people are confused about differentiating between the single-stage and two-stage air compressors. Whether you are a new user or a pro looking to replace your old air compressor, this two-stage vs. single-stage air compressor guide will be useful for both to find the best air compressor under 200 for your needs.
Two Stage Vs. Single Stage Air Compressor – What’s the Difference
Single Stage Compressor
The prime difference between single and two-stage compressors is their performance. In a single-stage air compressor, the air is sucked into the compression cylinder with the help of a filter by the action of the inlet valves and the movement of its pistons to the downside. When the required amount is drawn to the compressor cylinder, the inlet valves close and pass the signal to the crankshaft to rotate. The piston is then pushed upward to compress air and, meanwhile, pushing it to the exit valves. The pressure of air (120 psi) is discharged into the storage tank until when required.
Two-Stage Air Compressor
In a two-stage air compressor, the sucking and compressing of air are just like the single-stage, but the compressed air in stage two compressor goes through the second compression phase. The compressed air is not discharged to its storage tank after the initial phase of compression. The air is then further compressed for the second time by a piston in the second cylinder. In simple words, the air is double pressurized, which offers double energy as compared to a single-stage compressor. The air after the compression process is discharged into its storage tank for usage.
Differences between Single-Stage and Two-Stage Compressor
One of the prominent differences between these two air compressors is the number of times that the air is compressed between the tool nozzle and the inlet valve.
The air is compressed only one time in a single-stage air compressor, whereas in a two-stage air compressor, the air is compressed two times before it is discharged into the storage tank.
Do you know a single-stage compressor is also called a piston compressor? The air compressing process begins to take place within a single-stage compressor, and it starts with the air suction into the cylinder. The trapped air is then compressed in one stoke using a small piston at 120 psi. In the last stage, compressed air is moved towards the storage tank for usage.
Though the process of air compression is similar to the single-stage, there is only one difference. In a two-stage air compressor, the air is not sent to the storage tank but the small piston for another stroke. However, it is compressed at 175 psi. This double pressurized air is cooled and then delivered to the storage tank to perform various tasks.
The two-stage air compressor can produce high airpower as compared to the single-stage air compressor. That’s why most people prefer to use two-stage air compressors for large-scale and consistent applications. The only drawback of the dual-stage air compressor is that it is expensive, which makes it an ideal choice for factories and workshops.
On the other hand, a single-stage air compressor is a perfect match for independent craftsmanship. It can handle a variety of handle pneumatic tools that doesn’t exceed 100 psi. A dual-stage air compressor works best for pressing plants, auto shops, and other settings in which complicated arsenals of air-powered machinery are used.
Which Air Compressor is best? 2 Stage Or Single Stage Air Compressor
Now, this is the main question that most people are confused about to choose the best between the two air compressors. Well, we have briefly shared the differences and functions of both air compressors. In general, a dual-stage air compressor works more efficiently, runs cooler, and offers more CFM as compared to a single-stage air compressor. However, a single-stage air compressor has numerous advantages as well. It weighs less, costs less, and the electric model draws fewer amps as compared to the two-stage air compressor. It depends on your needs to choose the best air compressor under 200 for your tasks. A single-stage air compressor is perfect for small crews and individual tradesmen performing tasks like roofing, framing, sheathing or trimming. A two-stage air compressor is best for larger construction crews that need a large amount of air for a long period.
Final Words on 2 Stage & Single Stage Air Compressor Difference
Regardless of the size of the given operation, an air-powered tool is important to the productivity of craftsmanship and works for crews. If you are an individual woodworker or working in a crafts line, a single-stage air compressor can help you to perform your tasks efficiently at an affordable price. Whereas, for larger crews and big projects, a two-stage air compressor is a perfect tool.
