Screw compressors are the preferred choice of air compressor for industries around the world. This is because these units can provide a continuous stream of high quality compressed air, are hard working and reliable, robust, low maintenance, energy-efficient and versatile, and deliver the power required for demanding industrial applications. Because of this, rotary screw compressors are popular with various industries around the world, especially the energy, manufacturing, medical, pharmaceutical, and food and beverage sectors. Screw compressors are tailored to meet the specific needs and standards of each industry, ensuring optimal performance in automotive, food and beverage, wastewater treatment, chemical, pharmaceutical, and medical applications.

Compared to piston compressors, screw compressors offer significant advantages in large-scale or high-demand environments, such as continuous operation, greater efficiency, and suitability for industrial applications requiring a constant supply of compressed air.

What is a Screw Compressor (aka A Rotary Screw Compressor)?

Screw air compressors (also referred to as rotary screw compressors) are designed around two interlocking helical rotors – a male rotor and female rotor that turn in different directions. These compressors contain two rotors (male and female) that work together. Air is drawn into the compressor and trapped between the rotors, where the two rotors are compressing the air by forcing it into a decreasing volume of space, thereby increasing the air pressure. The two rotors are powered by the compressor’s motor, which drives the compressing process. Before entering the compression chamber, the compressed air is filtered to remove contaminants, and cooled before it’s ready for use.

Rotary screw compressors can be oil lubricated or oil free, and be fixed speed or variable, meaning that, whatever size you need and whatever you need it for, there will always be a suitable screw compressor for every application. This process ensures efficient and reliable air compression.

Oil Lubricated or Oil Free Rotary Screw Air Compressors

Whether you opt for an oil-lubricated screw compressor or an oil-free one will depend on your needs. If you need a compressor that will give you a continuous supply of compressed air, an oil-lubricated compressor will be your best choice. In oil-lubricated screw compressors, oil is used for lubrication, cooling, and sealing the compression chamber to maintain optimal performance. The oil cools the compression chamber and removes heat generated during the compression process, ensuring efficient and reliable operation. However, if air purity is vital to your operation, then an oil-free compressor is the only technology that will guarantee such a level of cleanliness. The oil-free design eliminates the need for lubrication within the compression chamber, which benefits maintenance and ensures the highest air purity. Pure compressed air is essential for industries that rely on contaminant-free production such as food manufacturing, pharmaceuticals, electronics and textiles.

Benefits of Screw Compressors

Screw compressors are designed to keep running costs to a minimum at the same time as providing as much compressed air as you need. The overall efficiency of screw compressors is high, making this type of compression technology extremely popular. Screw compressors also deliver significant energy savings, especially with variable speed models that adjust their operation based on air demand. Control is a key advantage, allowing precise management of compressor performance and noise levels to maintain operational efficiency and meet environmental standards. The main advantages are:

As rotary screw compressors run so smoothly and the screws have no physical contact, they are capable of providing continuous airflow. With no duty cycle to take into consideration, you can maximise production time and productivity. 

Operating compressors takes up a lot of energy, so the energy efficiency of a screw compressor will help to reduce your utility bills. If you are replacing your old piston compressor with a screw air compressor, you will notice considerable energy savings. 

Screw air compressors have no mechanical elements, which makes them markedly quieter than piston compressors. And with the additional sound proofing panelling on some models, even the largest screw compressors can be as quiet as the sound levels of a normal conversation. This means staff working in close proximity do not have to wear ear protection, making them more comfortable to work around. Click here to find out more about quiet air compressors

As screw compressors are smaller than their equivalent piston compressors, they take up less space on the shop floor. 

Rotary screw compressors are robust enough to continue working effectively even in temperature extremes.

As screw air compressors have very few moving parts, there’s less to go wrong. The rotary screws themselves do not touch each other, so there’s no wear and tear on the main compressor element and therefore very little possibility of damage. This means less maintenance and long service intervals, saving you money on looking after your equipment as well as adding to your profitability because there’s less production down time. 

We only sell high quality screw compressors that are designed to be robust and hard wearing, ensuring reliable operation at all times. As long as they are looked after well, they will work at full capacity for many years, with a great ROI. 

You will always find a screw compressor to match a huge variety of production processes. However big or small, portable or static, screw compressors are versatile enough for almost any industrial application. In fact, as long as they have a suitable power source, portable compressors can be used anywhere, indoors or outdoors. 

As a result of having zero down time, being energy-efficient, reliable, and needing little maintenance, you will benefit from the low life cycle costs of a screw compressor, contributing to its lifetime ROI.

Fixed-Speed and VSD Screw Compressors

Screw compressors come as fixed-speed models or have a variable speed drive (VSD). Fixed-speed compressors will run at a continuous speed, whereas VSD compressors will adapt the speed to the amount of compressed air being used. VSD technology optimizes energy efficiency by adjusting the compressor’s speed according to air demand, offering significant advantages over traditional fixed-speed compressors. Fixed-speed compressors are more suitable when there’s a need for a continuous operation, whereas VSD compressors are better suited when demand fluctuates, which can decrease the running costs considerably.

FAQs

A rotary screw compressor is one that uses the space between two moving rotary screws to pressurise the air. As the moving parts don’t touch each other at any point, the compressors are quiet, robust and hard working, and can provide a continuous supply of compressed air, benefiting even the most demanding users. 

We sell four main types of industrial air compressors: 

  1. Rotary screw compressors – using rotors that move in different directions to push the air into a decreasing amount of space to create the compressed air. Oil-lubricated and oil-free models are available depending on the purity of the air required.
  2. Vane compressors – for applications that only need moderate pressure and slower speeds.
  3. Piston compressors – the oldest model of compressor which is an ideal workhorse where continual use is not required.
  4. Portable compressors – for use in the field, or limited-use applications.

Many businesses choose rotary screw compressors over piston ones for a number of reasons. Piston compressors are extremely noisy, expensive to run, require lubricants, and need a lot of maintenance and more frequent servicing than rotary screw air compressors, which also means they’re more likely to go wrong, leading to expensive production downtime. Screw compressors are quiet, can be oil-free if air purity is a consideration, and are also more energy-efficient. So while piston compressors are cheaper to buy, their running and maintenance costs mean they are more expensive in the long run. Rotary screw compressors are versatile, making them the best choice for many and various applications. They are smaller than their piston equivalents and this, combined with their quiet operation, means they can be positioned at the point of use, making them more convenient for operators too. 

Rotary vane compressors are as quiet as screw compressors, but work at slower speeds. While they are ideally suited if you need something portable or only need a compressor for smaller jobs, they cannot compete with the output of rotary screw air compressors. 

Screw compressors are so versatile, they’re used by virtually all industries for various applications. Whether you need an oil-lubricated workhorse, an oil-free compressor that will guarantee the purity of your air, or a variable speed drive machine suitable for smaller work loads, we can find one to suit your needs. The main industry sectors that favour screw compressors are: 

  • Food and drink
  • Healthcare
  • Pharmaceutical
  • Chemical
  • Manufacturing
  • Mining
  • Energy
  • Textile
  • Construction
  • Automotive
  • Agriculture

As long as you look after your rotary screw compressor, it will need very little maintenance. As the main component of the compressor – the rotary screws – never touch each other, there is very little to go wrong, which means less maintenance and servicing is required than for, say, a piston compressor.
