Rotary Vane Compressors and Compressed Solutions

Wittig compressors efficiently transfer and compress a wide variety of gases and air. This type of compressor is particularly reliable, efficient, and enduring, making it a preferred choice in many industrial applications.

What is a Rotary Vane Compressor?

Theses compressors, also known as sliding vane compressors, are a type of displacement compressor. They use rotating vanes within a rotor to compress air or gas.

We appreciate these compressors for their functionality. The terms "sliding vane" and "rotary vane" both refer to the same compressor design;

"Sliding vane" emphasizes the dynamic movement of individual vanes within the rotor.

"Rotary vane" highlights the rotational action of the entire vane assembly.

Working Principle of Wittig Compressors

In this video you can see the operating principle:

The operation of rotary vane compressors is simple but effective.

A rotor with sliding vanes rotates inside an off-center chamber. As it spins, centrifugal force extends the vanes, creating a larger volume at the inlet and drawing in air. The rotor compresses the air or gas and discharges it at the outlet at the desired pressure.

Key Benefits of Wittig Rotary Vane Compressors

High Reliability: With fewer moving parts, these compressors offer consistent performance and minimal downtime.
Efficiency:They provide efficient compression with lower energy savings compared to other types of compressors. Theur simple mechanism ensure performance over time.
Durability: Wittig built rotary vane compressors for long-term use. They handle tough industrial settings and custom projects.Experts generally consider rotary vane compressors to be more durable than other types of compressors. They have fewer moving parts compared to piston compressors. They have a design less complex than rotary screw compressors. Their simple design permits to reduce the frequence of maintenance.
Flexibility: Suitable for a wide range of applications, from gas transportation to air compression in various industries.
Eco-Friendly:Rotary vane compressors compress air more efficiently and in an eco-friendly way. They have the benefits of high volumetric and mechanical efficiency and low rotation speed. Compressed air typically accounts for 10% of industrial electricity use, sometimes reaching 20%.Using better air compression and the right system size can cut energy use and CO2 emissions.The energy efficiency of the compressor is crucial for lowering its Life Cycle Cost, which includes all ownership costs. Remember, electricity makes up about 80% of a compressor’s total life cycle cost.Wittig air compressors with rotary vane technology make air efficiently, save energy, cut CO2, and lower costs.
Quiet Operation: Rotary vane compressors run quietly. Their unique vane and housing design reduces vibrations and noise, making them perfect for indoor or noise-sensitive areas.
Compact Design: Rotary vane compressors are smaller and more compact than other compressors. This makes them easier to install in tight spaces, suitable for both industrial and commercial use.
Low Maintenance: Rotary vane compressors have fewer moving parts, so they need less maintenance than other compressors.Operators or maintenance staff can easily do routine tasks like oil changes and filter replacements.

Typical Applications of Rotary Vane Compressors

Rotary vane compressors are efficient and adaptable, making them suitable for numerous industries. Common applications include:

Gas Transportation: Ideal for moving various gases in industrial processes.
Air Compression: Used in manufacturing, automotive, and other sectors requiring reliable air supply.
