Twin Lobe Compressor in India

JD VACUUM SERVICE is a leading manufacturer and supplier of Twin Lobe Compressor at a reasonable price from Ahmedabad, Gujarat, India.

A twin lobe compressor is a type of positive displacement compressor that uses two rotors or lobes that rotate in opposite directions to compress gases. The rotors have a unique shape that allows them to trap gas as they rotate and push it through the compressor to increase the pressure.



The twin lobe compressor is commonly used in a variety of industrial applications, such as in the oil and gas industry, power generation, and wastewater treatment. It is often used to compress gases like air, nitrogen, and methane, and is known for its reliability, efficiency, and low maintenance requirements.

One of the advantages of the twin lobe compressor is that it generates a uniform flow of gas without pulsations or surges, which can be important in some applications. Additionally, it is generally quieter than other types of compressors and can operate at higher speeds without causing excessive wear or damage.

However, the twin lobe compressor is not always the most efficient choice for all applications, and there may be other compressor types that are better suited for specific tasks. The choice of compressor will depend on factors such as the required pressure, flow rate, gas composition, and the environment in which it will be used.


The specifications of a twin lobe compressor can vary depending on the specific model and manufacturer. However, here are some general specifications that can give you an idea of what to expect:

  • Pressure Range: 0.1 to 1.5 bar (1.45 to 21.75 psi)
  • Capacity Range: 100 to 50,000 m3/h (59 to 29,411 cfm)
  • Maximum Speed: 5,000 to 8,000 RPM
  • Power Range: 1 to 500 kW (1.34 to 670 hp)
  • Discharge Temperature: Up to 160°C (320°F)
  • Discharge Nozzle Size: 2 to 24 inches
  • Gas Temperature Range: -20 to 150°C (-4 to 302°F)
  • Gas Inlet Pressure Range: -1 to 1 bar (-14.5 to 14.5 psi)

It’s important to note that the specifications can vary widely depending on the specific application and the type of gas being compressed. For example, compressing gases with a high molecular weight or high specific heat may require different specifications than compressing air or nitrogen. It’s always best to consult with the manufacturer to determine the specific specifications required for your application.

working principle

The working principle of a twin lobe compressor is based on the positive displacement of gas using two rotating lobes or rotors. The lobes or rotors are designed with a unique shape that allows them to trap gas between them as they rotate, which reduces the volume of the gas and increases its pressure.

Here is a step-by-step breakdown of how a twin lobe compressor works:

  1. As the two rotors or lobes rotate in opposite directions, they create a vacuum or low-pressure area in the space between them.

  2. Gas is drawn into this low-pressure area through the inlet port or suction port, filling the space between the lobes.

  3. As the lobes continue to rotate, the gas is trapped between them and carried around the outside of the compressor casing.

  4. As the space between the lobes decreases, the gas is compressed and its pressure increases.

  5. The compressed gas is then pushed out through the discharge port, which is located on the opposite side of the compressor casing from the suction port.

  6. The cycle then repeats, with the lobes continuously rotating and trapping and compressing gas as it flows through the compressor.

It’s important to note that twin lobe compressors are considered positive displacement compressors, which means they compress a fixed volume of gas per rotation. This makes them suitable for applications where a constant flow rate or pressure is required.


The clearance in a twin lobe compressor refers to the space between the two rotors or lobes as they rotate within the compressor casing. The clearance is an important parameter that affects the efficiency and performance of the compressor, as well as its reliability and durability.

Ideally, the clearance between the two lobes should be as small as possible to minimize the amount of gas that leaks back from the discharge side to the suction side of the compressor. This can improve the compressor’s efficiency and reduce the amount of energy required to compress the gas.

However, if the clearance is too small, the lobes can come into contact with each other, which can cause wear and damage to the lobes, as well as to the casing. This can also increase the risk of overheating and other mechanical failures.

The appropriate clearance in a twin lobe compressor will depend on a variety of factors, including the gas being compressed, the pressure and temperature conditions, the operating speed, and the manufacturer’s specifications. As a general rule, the clearance should be set according to the manufacturer’s recommendations and monitored regularly to ensure that it remains within the acceptable range. If the clearance becomes too large or too small, it can indicate a problem with the compressor that should be addressed promptly to avoid further damage or inefficiencies.
