AULISS Rotary Screw Air Compressor

Industrial Rotary Screw Air Compressor is a machine designed based on the screw air compressor working principle of volume changes caused by the rotation of twin screws (also known as Yin and Yang rotors). The industrial screw type air compressor can intake natural air and complete the work through several internal processes, eventually discharging compressed air that meets the pressure requirements. This machine is referred to as an industrial screw air compressor.

Types of Rotary Screw Drive Air Compressors for Sale

Micro-Oil Screw Air Compressor

A micro-oil screw air compressor is a type of industrial rotary screw compressor that uses a small amount of oil for lubrication and sealing purposes. This type of industrial screw compressor is designed based on the principle of volume changes caused by the rotation of twin screws, also known as Yin and Yang rotors.

Screw Blower

A screw blower is a type of blower that uses two screw elements, also known as rotors, which turn in opposite directions.

Screw Vacuum Pump

The industrial screw type air compressor can be pumped containing a large amount of water vapor and a small amount of dust gas occasions, in the domestic major pharmaceutical and chemical enterprises are widely used.

Compressed Air Treatment Equipment

The need to configure compressed air purification equipment (industrial screw air compressor after-treatment equipment) to purify the impurities in the compressed air, freeze dryer is one of the equipments used to remove water. There are two types of air compressor dryers commonly used in the market, freeze dryers (cold dryers) and adsorption dryers (suction dryers).

The Role of Industrial Rotary Air Compressors in Industrial Applications

Industrial rotary air compressors play a crucial role in various industrial applications due to their ability to provide continuous and reliable compressed air. Here are some of the key roles they play:

In all these applications, industrial rotary air compressors including micro screw compressor are preferred due to their durability, efficiency, and ability to provide a steady supply of high-quality compressed air. They are also easy to maintain and operate, making them a reliable choice for various industrial applications.


  • Manufacturing Industries: The industrial screw type air compressor is widely used in manufacturing industries such as automotive, food and beverage, and electronics. The air compressors for metal fabrication powers a wide range of tools and machinery, including drills, spray guns, and robotic arms, which are essential for production processes.

  • Construction: In the construction industry, the industrial screw type air compressor is used to power heavy machinery and pneumatic tools such as jackhammers, compactors, and concrete breakers. It is preferred due to their high efficiency and ability to work for long hours without overheating.

  • Pharmaceutical Industry: In the pharmaceutical industry, the wholesale screw air compressor is used in processes such as material handling, drug manufacturing, and packaging. The industrial rotary screw air compressor provides clean and oil-free air, which is crucial in maintaining the high hygiene standards required in this industry.

  • Agriculture: In agriculture, these industrial rotary air compressors are used in irrigation systems, crop spraying, and in the operation of various farm machinery.

  • Energy Sector: In the energy sector, the instrument air compressor in power plant is used for starting and purging gas turbines, cleaning boiler tubes, and in the operation of pneumatic valves and controls.

  • Mining: In the mining industry, these industrial rotary air compressors are used to power drilling machinery, ventilation systems, and for material handling.



Screw Air Compressor Working Principle

The cylinder of the wholesale screw air compressor contains a pair of intermeshing spiral rotors, which rotate in opposite directions. The main rotor, also known as the convex rotor, is driven by the motor. The other rotor, which we call the concave rotor, is mainly driven by the main rotor through oil spraying to form an oil film. When the spiral rotor groove passes through the air intake, it is filled with gas. When the rotor rotates, the rotor groove is sealed by the casing to form a compression chamber. After the rotor groove is sealed, lubricating oil is sprayed into the compression chamber, which will play a role in sealing, cooling, and lubrication. When the rotor rotates to compress the lubricant and gas, we collectively refer to this as an oil-gas mixture. The volume of the compression chamber decreases and the oil-gas mixture is discharged to the exhaust port. When the oil-gas mixture in the compression chamber passes through the exhaust port, the oil-gas mixture is discharged from the screw drive air compressor, completing a process of air intake, compression, and exhaust. The working cycle of the industrial screw type air compressor can be divided into three processes: air intake, compression, and exhaust. As the rotor rotates, each pair of intermeshing gears completes the same work, converting mechanical energy into the kinetic energy of the gas!



How to Choose the Right Industrial Rotary Air Compressors?

1: Consider the brand of the screw machine, the rotary screw air compressor manufacturers' production and after-sales service capabilities. The brand directly determines the product performance and stability. 


2: Pressure demand, a normal industry 8 kg wholesale screw air compressor is enough, special industries like laser cutting choose 16 kg. 


3: Air consumption, match the industrial rotary screw compressor according to the air consumption (reserve 10% to 20% of space). If it’s too large, it will increase unnecessary purchase costs and energy consumption, if it’s too small, the pressure will not go up and affect production.  


4: Specific power, the smaller the better. With the same air pressure, the larger the exhaust volume of the same power model, the more power-saving it is, which is what we call energy-saving.


Advantages of Rotary Screw Air Compressors Compared To Other Types

Advantages of Rotary Screw Air Compressors Compared To Other Types

01

Compact machine structure, small size, small footprint, light weight.

02

High thermal efficiency, less processing parts, the total number of parts of the wholesale screw air compressor is only 1/10 of the piston type. Fewer wearing parts of the machine, safe and reliable operation, simple operation and maintenance.

03

No pulsation of gas, smooth operation, the unit is not high on the foundation does not require a special foundation.

04

Oil Is Injected Into The Rotor Cavity During Operation, So The Exhaust Temperature Is Low. The industrial rotary screw air compressor can be operated under higher pressure.

05

Insensitive to wet formation, wet vapor or a small amount of liquid into the machine, there is no danger of liquid shock.

06

The effective stroke of compression can be changed with the help of slide valve, and stepless cooling adjustment of 10~100% can be carried out.
