Are you looking for rotary screw air compressors? If it is your first time buying these compressors, you need to go through this guide for more information. If you are unsure whether you need a rotary screw air compressor for your project, this should be a good starting point. In this rotary screw air compressor guide, we cover everything about a rotary screw air compressor to help you make an informed buying decision. Here is a sneak peek into what you will learn:
Rotary screw air compressors are a type of air compressor that uses a pair of helical screws to produce compressed air. The turning of the screws ensures continuous delivery of compressed air. Rotary screw air compressors are most suitable for applications that require high CFM and continuous flow of compressed air. In other words, rotary screw air compressors are mainly industrial air compressors.
The working mechanism of a rotary screw air compressor is more straightforward. These sets depend on the rotation of helical screws to compress air. These screws or rotors turn as they interlock to create a series of air chambers. Air is forced through the rotors and squeezes into the chambers.
This working mechanism explains why a rotary screw air compressor is considered a positive displacement air compressor.
How do you know if a rotary screw air compressor is the most suitable option for your project? Here are some ways to know if you need a rotary screw air compressor in the first place.
A rotary screw air compressor is perfect for you in the following situations:
In the same way, you may not need a rotary screw air compressor in the first place. But how do you know this? Here are some situations that may call for an alternative type of air compressor:
In these situations, you may need a reciprocating air compressor instead of a rotary screw air compressor.
Rotary screw air compressors are one of the most used types of air compressors in the world. These air compressors are referred to as the workhorse for industrial applications for various reasons. However, they do not come without drawbacks. Here are some of the advantages and disadvantages of rotary screw air compressors.
Choosing the best rotary screw air compressor can be an overwhelming task. Here are some factors you should consider to make your work more manageable.
Buy a portable rotary screw air compressor if you need to work in different locations. Accordingly, a portable air compressor is suitable if you do not have reliable electric power. On the other hand, a stationary rotary screw air compressor is best used in industrial applications that do not require you to move from place to place.
Do you plan to use the air compressor indoors or outdoors? A compressor for outdoor applications is more exposed to adverse weather conditions and better cooling. This aspect may call for extra mechanical protection.
You have three options to choose from. Do you want a belt-driven, gear-driven, or direct-driven rotary screw air compressor? Belt-driven and gear-driven screw air compressors are more versatile but have less efficiency. More advanced technologies allow compressors to have a variable frequency drive that helps you manage power consumption under different loads.
The air volume or deliver rate (CFM) is crucial. This is the amount of air you get from the compressor per minute.
What amount of pressure do you need to run your power tools? The pressure is always indicated in psi, and most equipments require about 70 psi to 90 psi.
The horsepower is directly linked to the size of your air compressor. You should identify the horsepower you need for your applications.
Think about your air compressor tank as the storage of compressed air. If your projects and applications require fluctuating amounts of compressed air, you may need a larger tank size. There are many things involved in deciding the size of a compressor tank. For instance, you should think about the floor space, your budget, and the compressor’s control system.

Rotary air compressors are being used in numerous industrial, commercial, and even home-case applications because of their high-powered performance, reliability, durability, and much more.
This article is going to discuss all rotary air compressors, their types, and what top manufacturers and considerations you might want to keep in mind before making the final purchase.
What are Rotary Air Compressors and their Types?
Rotary air compressors are widely-used industrial tools that have now replaced the old piston compressors. These are mainly used where a large volume of compressed gas is needed, such as large chillers or refrigerators, or to power up demanding tools and equipment such as jackhammers and wrenches.
Unlike the traditional piston compressors that were used in the past, there are neither valves in the present ones, nor any other force that can result in an unbalance in rotary screw air compressors.
Thus, this makes the modern screw air compressors much more efficient, as these are able to get the job done much quicker, and that too with better efficiency.
Furthermore, modern rotary air compressors are more advanced than the traditional ones and have numerous new features added, such as portable rotary screw air compressors, that make them very convenient and easy for us to move them around.
There are several types of rotary air compressors, such as:
Screw compressors
Screw air compressors are commonly used as they comparatively make less sound and are able to produce a large volume of compressed air in a short period of time.
With a screw compressor, you can opt for either an oil-based option or an oil-free option. Moreover, you also benefit from lower maintenance costs with screw compressors.
Scroll compressors
These are different from screw compressors as unlike the latter, air enters from the outside edge of the scroll. From there, it gets pulled inwards to the middle of the spiral and is then pressured before it is forced down through the outlet in the center.
Vane compressors
In this type of compressor, the air enters through a specific inlet. Then, there are rotating vanes that push this air into a tighter edge of the circle. Thus, the air is compressed using the least effort.
Lobe Type Compressors
In this type of compressor, there are spinning wheels that have cuts on their opposite ends. When the air enters, it fills these gaps and then gets spiraled around across the chamber. This forces it to compress within that space.

Type of Drive System
You will have to choose between an electric-powered motor and a diesel-powered motor. However, it is important to know that an electric-powered one will cost you comparatively less and will also require minimum maintenance.
Tank size
With different tank sizes that come with the air compressors, you need to find out which size you want your storage tank to be. Remember, if you go for a larger tank, you will have more pressured air available to carry out specific tasks. However, with smaller tanks, you will require more work for the same output.
