The Complete Buying Guide: Rotary Air Compressor
Rotary air compressors have replaced the traditional piston air compressors due to various reasons. The modern rotary compressors are far more efficient and heavy-duty. Moreover, because of their high performance, rotary air compressors are best suited for industrial, commercial, as well as home-based applications. They are able to seamlessly power up demanding tools and equipment and are even used in large chillers and refrigerators.
This article is going to focus on rotary air compressors, how they are different from traditional piston air compressors, troubleshooting rotary air compressors guide, top brands, and other aspects you should consider when going out to purchase one. Read on to find out!
Rotary Air Compressors Available in the Market
To date, there are numerous types of rotary screw air compressors you’ll come across in the market. Which one you’ll go for, depends entirely on your needs and requirements. Here are the common types of rotary screw air compressors you will find in the market:
Rotary screw air compressor single phase
Single-phase rotary screw air compressors are designed for a full, heavy-duty. When purchasing a single-phase rotary screw air compressor, you will not only improve the overall efficiency of the task but will also improve the functionality of your commercial applications.
Moreover, there is a wide range of single-phase rotary screw compressors you’ll find in the market. Some are also able to boast a capacity larger than the typical 7.5 HP limitation.
Gas-powered rotary screw air compressor
When choosing a rotary screw air compressor, you’ll have to choose between an electric-powered air compressor or a gas-powered air compressor.
Gas-powered rotary screw air compressors are just as powerful as any other type of rotary screw air compressor you might come across. However, a gas-powered rotary air compressor does not necessarily require a hydraulic drive system in order for it to work well.
If you go for gas-powered rotary screw air compressors, you can power up just about any heavy and demanding tools and equipment you can think of.
Rotary screw air compressor with dryer
When using an air compressor, you’ll notice water in the compressor, in the form of either moisture or aerosol. Thus, this is when a rotary screw air compressor with a dryer is going to come in handy. This is going to prevent any vapor or aerosol from remaining in the compressor, which can actually damage the compressor’s body and also the valves and pipes. Thus, this will reduce the performance and efficiency of the air compressor over time.
Portable rotary screw air compressors
Portable rotary screw air compressors are comparatively smaller in size. However, because of their portability feature, they are quite easy to move around and place wherever you want to. In case you want a rotary screw air compressor for outdoor use, then you should opt for a portable one. However, mind you, portable rotary screw air compressors aren’t as powerful as compared to stationary ones.
How Does a Rotary Air Compressor Work?
How rotary screw air compressors work is no rocket science.
Rotary screw air compressors work by trapping the air between two meshed rotors inside of it. This helps to decrease the air’s volume that is trapped inside as it makes its way down from the rotors inside the compressor.
Therefore, this decrease in the air’s volume results in compressed air. Now, through the rotary screw air compressor pump, the compressed air can now be used for powering any demanding tools and equipment, or for various other applications as required.
If you’re wondering what the maximum delivery pressure in a rotary air compressor is, then let us tell you that most air compressors are manufactured to work to a maximum of 175 psi. Most of the rotary screw air compressors you’ll come across will work efficiently anywhere between 90 psi and 125 psi.
There is another air compressor you might come across- a reciprocating compressor. The main difference between reciprocating and rotary air compressors is that the latter is used where a larger volume of air at lower pressure is required. However, a reciprocating compressor is best suited when a smaller volume of air at high pressure is needed.
Rotary Air Compressor VS Piston
The main difference between a rotary screw air compressor and a piston is that the latter is able to efficiently work at temperatures ranging from 300°F – 400°F. However, a rotary screw air compressor, on the other hand, operates at a much lower temperature which is anywhere between 170°F and 200°F.
Also, in a piston, the engine has up-and-down moving pistons that are able to convert pressure into rotational motion. However, in a rotary screw air compressor, the rotary engines include a radial layout with an odd number of cylinders.
Top Rotary Air Compressor Brands
There are several rotary air compressor brands you don’t want to miss when you’re opting to purchase one. Here, we have listed the top 5 brands to look out for.
Quincy rotary screw air compressor
Quincy is one of the best ranked in the market if we talk about their rotary air compressors. With Quincy, you can choose from a wide range of horsepower and configurations.
