Air compressors are extremely useful, especially for industrial and commercial purposes. There are different types of air compressors that are available in the market for your use. If you are looking for what type of air compressor to buy, one of the most popular ones are the 2 stage air compressors.

These double stage air compressors come with two cylinders. One of the cylinders is a high-pressure one and the second one is a low-pressure cylinder. This is very useful as the low-pressure cylinder pumps almost to half the end pressure and then the compressed air is cooled and compressed further by the high-pressure cylinder.
 
Perfect for industry uses, automobile shops and more, these double stage compressors have a capacity that reaches up to 50 CFM while the pressure can reach a maximum of 175 psi.

If you are planning on buying a double stage air compressor, here are few tips to help you choose the perfect one:
 
1. Need
Look out for the kind of tools that will need the kind of pressure that you get with a 2 stage air compressor. Due to the high pressure, you can get, keep the tools you will be using and the pressure they will require in mind and choose accordingly.

2. Capacity
If you do not require too much pressure but need a lot more capacity, then you are better off with another type of air compressor. The 50 CFM restriction might cause a lot of problems if you need more capacity. You can determine this by seeing the amount of air that will be consumed by your machine and the tools together. If you think space is too less, go for a rotary screw compressor since it will be a better option, capacity-wise.

3. Maintenance
If you are planning on getting a double stage air compressor, you need to sure that you can afford its maintenance. Unlike the single stage compressor, this has two working pistons which will inadvertently mean more maintenance. If you can’t take care of it, it might end up being a loss for you.

4. Duration
Most of the people who decide to get this are looking for a long-term investment especially for industrial uses. Since these air compressors have two pistons, the outputs are higher and have a longer working less due to less generation of heat. Look for the amount of time you need it and then go for the compressors that fit your timeline the best.

5. Electricity
The 2 stage air compressors all come in different sizes. The bigger it is, the more electricity it will consume. Look out for the amount of power lines and electricity it will consume before opting for the right air compressor.
With so many different things to look out for, a little research is necessary. Keep your needs in mind before going for the air compressor you think will suit your needs the best. Since it is a long-term investment, you need to be sure that you have picked the right one!
