Rotary Screw Air Compressor: An Energy-Efficient Solution to Your Business

The air compressor market with a gigantic revenue of 37 Billion USD. It is generally used in homes, offices, industries, and multiple other setups. Regardless of their qualities, the majority of air compressors possess either of two common building designs. ‘Rotary Screw’ or ‘Reciprocating Piston’ air compressors.

Both of these designs are unique in their own way. However, rotary screw air compressors are more sustainable, energy-efficient, clean, quiet, and reliable even when used continuously. Therefore, if you own an industry that needs a continuous supply of large volumes of high-pressure air, then rotary screw air compressors are surely your way to go!

In this blog, we will be spitting facts and figures about rotary screw air compressors. You are also going to understand the potential upsides and downsides of this particular type. So, let’s read ahead, before stuffing your industry with them.

What is A Rotary Screw Type Air Compressor

As the name suggests, the rotary screw air compressor uses two rotating screws to compress the incoming air. These two screws are designed and placed in unison to produce compressed air effectively and efficiently.

In comparison to piston air compressors, which only use a moving piston to compress the air, the working of rotary screw compressors is somewhat more complicated. Therefore, there always remains an ambiguity about its working. Don’t worry as you have us here. We at Lingyu Machinery believe in 100% transparency. Therefore, just like us, the manufacturers, our customers should also have a proper understanding of these compressors before making a purchase. Read ahead!

How Do Rotary Screw Air Compressors Work?

Rotary screw air compressors work on a simple yet clever principle of positive displacement. I know, too technical for you. Don’t stress out! We are taking a step back to its simpler explanation. Screw compressors comprise of two meshed helical screws, which are also known as rotors. As discussed before, rotors work in unison to reduce the volume of the air as it passes through them.

Components & Working of Rotary Screw Air Compressors

Rotary screw compressors use these two helical screws, rotors, to displace the air into a high-pressure zone resulting in compression. In the case of dry-running air compressors, ‘male and female rotors’ maintain a precise alignment with the help of timing screws. While, in oil-flooded air compressors, lubricating oil works with ‘driving and driven rotors’.

In simple words, no matter the type of screw compressor, the goal is to make a hydraulic seal that pushes the air into a compressed form. This compressed air finds its use in a variety of industrial, medical, and domestic applications. So, how can we move forward without having a brief overview of their top-notch applications?

Rotary Screw Air Compressor Applications

The screw compressor has found its use in a wide range of businesses performing both small and large-scale operations. This raises the question of why many professionals rely on them for their everyday production capacity. The answer lies in the vigorous design and lack of duty cycle, making the whole process of air compression quick.

To summarize, screw compressors are highly suited to heavy-duty industrial operations in major manufacturing sectors. Construction, aerospace, automotive, food, brewing, and several other industries are the key accelerators responsible for the exponential growth of the global screw compressors market.

Types of Rotary Screw Air Compressors

Often with cars, we witness flat tires or stubborn dust spreading over the windscreen. What we need in both of these cases, is an air compressor. One to inflate the tire and the other to wash the car, a pressure washer.

In fact, we have been around air compressors even in our homes. We didn’t even know it – as they are present in our refrigerators and air conditioners. In short, every day, we encounter air compressors in a wide range of places with an even wider range of uses.

Just like any other air compressor, rotary screw air compressors can be of different types. However, some of the most energy-efficient rotary screw air compressors that we offer our valuable customers at Lingyu Machinery are:

  1. Oil-injected rotary screw air compressors: It needs oil for lubrication and cooling during the compression process.
  2. Oil-free rotary screw air compressors: It uses alternative techniques such as specialized coating to reduce friction and ensure efficient working.
  3. Single-stage rotary screw air compressors: It directly compress the air into the desired pressure.
  4. Two-stage rotary screw air compressors: There are two sets of rotors each compressing the air one at a time.
  5. Variable speed drive (VSD) compressors: It operates at variable speeds to match the demand of compressed air.
  6. Fixed speed screw compressors: It works at constant speed to give a continuous supply of compressed air.

Advantages & Disadvantages of Rotary Screw Compressors

Regardless of how a product is, it always comes with some benefits and drawbacks. As we believe in transparency, here is a brief overview for our valuable customers about the advantages and disadvantages of rotary screw type air compressors.


We have already addressed the advantages of screw compressors multiple times in the blog. Yet, here are the top reasons why several businesses favor the use of screw type compressors in their working facility.

  • Non-stop Working

Unlike other air compressors, screw compressors have no duty cycle. You don’t need to shut them off and on. Because they can maintain a non-stop supply of pressure and air supply.

How does it help your industry? It can continuously work with little to no downtime enabling your compressors to work more effectively by consuming a substantially low amount of fuel. The use of screw compressors not only encourages your industry to function hassle-free but also conserves fuel avoiding a blow on your pocket.

  • Robust Design

Screw compressors are made to withstand extreme environmental stresses such as rigorous changes in temperature. At Lingyu Machinery, we offer your businesses strong-made designs of screw compressors. They can easily withstand a temperature up to 100 ℃. Above this temperature, our compressors sound an alarm. Then it can cut off the power supply to prevent unnecessary damage.

In fact, their sturdy designs also enable them to maintain high airflow rates. This particular quality makes them a perfect option for business owners who want to run heavy equipment and pneumatic tools easily and effectively.

  • Low Maintenance Cost

You are now well aware that screw compressors don’t involve parts that continuously move and contact each other. Therefore, the chances of wear and tear and subsequently the maintenance cost are reduced to the bare minimum.

  • Noise Free

Imagine you enter a working facility, the noise of which is giving you a headache. Do you think, the staff can work 24/7 in that toxic setting? Absolutely not! They will only work if they are compelled to do that. As a business owner, you should not only focus on the working efficiency of your machines but also your employees. With screw compressors, you are rest assured that your employees are getting a noise-free background perfect for efficacious working. Smooth moving parts with minimum to no contact are the two main reasons behind the quiet operation of these devices.


A rotary screw air compressor is a big investment!!! The only drawback it has.

If you are new to this industry and want to add some energy-efficient compressors to your setup, you will need to invest a good deal of dollars in it. The initial investment for purchasing and installing a rotary screw air compressor is relatively high compared to other types of air compressors. Despite their efficiency and reliability, investment costs can pose financial challenges for businesses. Especially smaller ones, it will impact their budget.

However, the efficient working and low maintenance cost really make this investment worth a while.

Rotary Screw Compressor Maintenance

Regardless of the top-notch quality of the screw compressor, it is a machine. Like any other machine, it also needs regular inspections. Therefore, if you want it to run smoothly and efficiently for a generous period, you should be more swift about its maintenance.

Regular inspections should involve checking the quantity and quality of the oil as well as changing the oil and filters as needed.
In order to avoid leaks and retain effectiveness, it is essential to check belts, hoses, and connectors for wear or damage. The system remains clean by cleaning or changing the air intake filters.

Regular evaluation of the safety features and pressure settings ensures safe and efficient compressor operation, reducing downtime and increasing output.
