Rotary Screw Air Compressor
A rotary screw air compressor is a type of gas compressor, such as an air compressor, that uses a rotary-type positive-displacement mechanism. The gas compression process of a rotary screw is a continuous sweeping motion, so there is very little pulsation or surging of flow, as occurs with piston compressors.
Rotary screw air compressors operate by trapping air between two meshed rotors and reducing the volume of that trapped air as it moves down through the rotors. This reduction in volume results in compressed air, which can then be used to power air tools, inflate tires, or in numerous other applications.

Introduction to Rotary Screw Air Screw Compressor
When it comes to an air compressor, what is the first thing that comes into your mind?
To most of us, the first thing that will come into our mind is a device that forces a stream of air to pass through a small space.
Some people even call them piston compressors since they use pistons to control the movement of air.
The air is then collected on the other end of the tank.
So, what about a rotary screw air compressor?
This is a newer and improved version of the air compressor.
The most outstanding feature about them is the rotation. They rotate while pumping a stream of air.
Screw air compressors are considered a replacement of the traditional air compressors.
Are you planning to buy a compressor?
Read on as we guide you on everything you need to know about a rotary screw air compressor for sale.
What is Rotary Screw Air Compressor?
A rotary screw air compressor is a type of air compressor that works using the principle of rotary displacement mechanism.
This displacement is caused by the movements of two pairs of spiral rotors. As they are displaced, a stream of airflow is created.
This type of air compressor is mainly used in areas where a large volume of high-pressure air is needed. They are a perfect replacement for the piston compressors.
Basically, a rotary screw air compressor operates by trapping a stream of air between its two meshed rotors.
By doing so, it reduces the volume of the trapped air, which is moving downwards on the rotor.
The reduction of air volume leads to compressed air. This air can be used for large-scale applications. However, they are also applicable to small-scale uses.
For a small business, you can get yourself a small screw air pump for sale.
The rotary sweeping motion of the rotary screw ensures that there there is a minimal pulsation, spurts or interruptions.
In other words, the supply of air will be smooth and consistent.
The screw compressor also operates quietly as compared to other types of air compressors.
Quite a good percentage of industrial machines depend on the rotary air compressors for their operations.
Eliminate this device, and the whole production line will come into a standstill.
How a rotary screw air compressor works
Types of Rotary Screw Air Compressor: oil-injected vs Oil-Free Rotary Screw Compressor
There are two main types of air compressors for sale. These are oil-injected rotary air compressor and oil-free air compressor.
As the names suggest, one type uses oil while the other type does not use oil.
Oil-injected rotary screw air compressors have oil on the chamber cylinder and bearings. The purpose of the oil is to provide the much-needed lubrication.
Once the ends of the rotor seals are well-lubricated, the pressure is generated at a very fast rate. This pressure ensures that air is compressed at a single stage.
Oil is then separated before the air exits the system. This is done to prevent any form of lubrication.
The oil is then recycled to the rear end for reuse.
The good thing about oil-injected screw air compressors is they provide high pressure on a continuous basis.
Oil-free rotary air compressor, on the other hand, do not flood the compression chamber with oil. The lubrication is due to the anti-corrosive agents that the bearings come with.
Although this type of rotary screw compressor is quite expensive, you don’t have to worry about the incidences of oil contamination.
For this reason, they are used in sensitive applications such as food and chemical industries.
Power Ratings of Air Compressors
Apart from the two types, that air compressors are further subdivided into different categories depending on their power ratings.
Probably you have heard of small rotary screw air compressors and large ones. The difference is usually in terms of their power ratings.
You can choose to buy a 5hp rotary screw air compressor, 7.5hp rotary screw air compressor 10hp rotary screw air compressor 15 hp rotary screw air compressor and even bigger compressors such as 20hp rotary screw air compressor 30hp rotary screw air compressor and 50hp rotary screw air compressor.
Components of Rotary Screw Air Compressor
Parts of rotary screw compressor source Engihub
For a rotary air compressor to operate efficiently, all of its components must be intact and operate as a unit.
But what are these key components of a rotary screw air compressor?
This component is usually considered as the heart of a rotary screw air compressor.
Whether you are buying a brand new or a used rotaryair compressor, you should ensure that the air ends are present.
This is the component through which air is compressed.
A stream of air enters the compressor through an inlet valve. It is then mixed with some oil as it undergoes the compression process.
2. Compression Cylinder
The compression cylinder is a component that houses the roller.
The airstream that has been collected is channelled through the chambers of the cylinder then into the spinning rotors.
The amount of cylinder in a unit will determine the number of stages and the amount of pressure to be generated.
3. Air filters
The air filters are positioned right at the opening of the compression valve. They filter dust, moisture and other solid particles that are likely to cause some mechanical damage inside the system.
Other air filters are positioned within the chamber components, and they do the same task of filtering solid particles.
4. Oil filters
These components are found oil-lubricated rotary screw compressors. They are positioned inside the walls of the rotating chambers and near the discharge valves.
They filter off the air that is being discharged from the compressed stream of air.
The bearings of a rotary screw air compressor are located on the ends of both the rotors. Their main function is to ensure that the rotors are in a stable and secure position.
The bearings also ensure that the rotors rotate evenly and have a balanced load capacity.
Naturally, bearings are designed to minimize the effect of friction on the air compressor. They come in different designs depending on the size and desired output of the air compressor.
The motor is responsible for powering the rotation of the rotors. You can adjust the power settings of the motor so that it can affect the rate of rotation.
7. Discharge valve
The discharge valve is positioned at the extreme end of the suction valve. It signifies the end of the air compression cycle.
This valve receives air that has low pressure and releases it to the holding tank. It can also discharge this air for its relevant application.
8. Control system
Just as the name suggests, the function of the control system is to control the operation of the rotary screw air compressor.
You can use it to determine the output that you intend to get from the system.
The control system has a display monitor which you can use to gauge the performance of other air compressor components.
Well, these are the main rotary screw air compressor parts.
However, you can find customized rotary screw air compressor, which is likely to have extra components.
For instance, you can easily buy a used rotary screw air compressor with dryer.
