Transport pneumatique solutions are used in various industries to transport goods and materials efficiently. Air-powered conveyance systems are a key part of many manufacturing processes.
In the food industry, pneumatic transport is used to move ingredients and finished products through cleanrooms and production areas. This helps maintain a sterile environment and prevents contamination.
Pneumatic systems can transport a wide range of materials, from lightweight powders to heavy bulk materials. They can also be used in tight spaces, making them ideal for use in confined areas.
The automotive industry relies heavily on pneumatic transport to move parts and components through production lines, reducing the risk of damage and improving efficiency.
What is Pneumatic?
Pneumatic transport is the process of using compressed air to convey bulk materials from one point to another through pipes, such as from a truck to a silo or through various stages of an industrial installation.
The reality of pneumatic transport is more complex than it seems. Different systems of pneumatic transport exist, each using various air pressures. The choice of the right system depends on the material being transported and the distance to be covered.
Selecting the ideal pneumatic transport system can have significant benefits for companies in terms of investment, operating costs, and carbon footprint.

Types of Pneumatic Systems
There are different types of pneumatic systems that can be used depending on the specific needs of an organization.
A unidirectional system was the initial concept of pneumatic transport, but it has since evolved to include multiligne, point à point, and ligne unique models. Each type brings its own value and serves a specific purpose.
These systems use a network of pipes where air compression and aspiration are used to transport capsules containing important objects to a desired location within a building. The pipe material can be either steel or PVC, depending on the type of system needed.
Les Différentes
In a pneumatic system, there are three distinct phases of material transport: the dilute phase, the dense phase, and the transitional phase. The dilute phase is characterized by a low concentration of material in the air stream.
The dense phase, on the other hand, involves a higher concentration of material, making it ideal for transporting abrasive or heavy materials. This phase is particularly useful for conveying materials over long distances.

A transitional phase occurs when the material flow rate changes, causing the system to switch between dilute and dense phases. This phase is often temporary and can be influenced by various factors, such as material properties or system design.
A pushed dense phase pneumatic transfer system is used for transporting powdery materials to production equipment over long distances, offering a higher capacity than aspiration systems. This type of system is well-suited for abrasive materials, regardless of flow rate or temperature.
In a pushed dense phase system, the material is propelled through the transfer line by air, with one or more inlets for the material. The material is then transferred to the conveying lines via a rotary transfer chamber.
Système Aspiré Dense
The system aspiré dense, also known as the dense phase pneumatic conveying system, is a type of pneumatic system that uses a vacuum to transport powders and granules through a network of tubes.

It's a popular choice for industries that need to transport large quantities of materials, such as pharmaceuticals, food, and chemicals. The system is designed to minimize the risk of material degradation and contamination.
One of the key benefits of the system aspiré dense is that it doesn't produce attrition or demixing of the transported materials, which means the materials arrive at their destination in their original form. This is in contrast to other types of pneumatic systems that can cause the materials to break down or become mixed with other substances.
The system aspiré dense uses a pump to create a vacuum that pulls the materials through the tubes, rather than pushing them with compressed air. This makes it a more energy-efficient option for long-distance transportation.
The system is commonly used in applications where materials need to be transported from multiple points of origin to a single point of destination, such as from storage silos to processing equipment. It's also used in situations where materials need to be transferred from containers or big bags to processing equipment.
The system aspiré dense is designed to work in a confined space, which makes it ideal for use in facilities with limited space. It's also a good option for industries that require a high level of cleanliness and hygiene, as it minimizes the risk of contamination.
Overall, the system aspiré dense is a reliable and efficient option for transporting powders and granules through a network of tubes. Its ability to minimize material degradation and contamination makes it a popular choice for a wide range of industries.
History of Pneumatic Systems
The history of pneumatic systems is a fascinating story that spans centuries. The concept of pneumatic systems was first described by Héron d'Alexandrie in the 1st century AD.
The first practical application of pneumatic systems was in the 19th century, when they were used to transmit telegrams and mail in major cities. In 1853, a pneumatic tube system was installed between the London Stock Exchange and the main telegraph station in London, a distance of 200 meters.
The London Pneumatic Dispatch Company developed and expanded this system, and by the mid-19th century, pneumatic tubes were being used in several major cities, including Paris, Berlin, and Vienna. These early systems were used to transmit mail, telegrams, and other documents quickly and efficiently.
Here's a brief timeline of some of the key milestones in the development of pneumatic systems:
- 1853: London Stock Exchange to main telegraph station, 200 meters
- 1864: Sydenham, 547 meters
- 1865: Berlin, 400 kilometers
- 1866: Paris, initially for administrative use
- 1875: Vienna, in service until 1956
- 1887: Prague, still in operation today
- 1910: Alger and Marseille, also in service for several decades
These early pneumatic systems were an important innovation in transportation technology, allowing for rapid and efficient movement of mail and other documents. While they eventually gave way to newer technologies like the telephone and email, pneumatic systems continue to be used in various forms today, including in banking, healthcare, and retail settings.
Pneumatic System Applications

Pneumatic system applications are diverse and widespread, making them a valuable asset for various industries. In hospitals, pneumatic systems can transport blood samples from nurses to the lab for testing.
In commercial spaces, they can send cash from cashiers to the safe after a day's work. Manufacturers also use pneumatic systems to send quality control samples to their labs.
Using pneumatic systems can save time, free up personnel to focus on more critical tasks, and ultimately be more cost-effective for business owners.
Quelles Sont les Méthodes de Matériaux?
There are several methods of pneumatic material transport, including the different phases of transport.
The transport pneumatique de matériaux involves the use of compressed air to move materials through a system of pipes and valves.
In the different phases of transport pneumatique, materials are first conveyed through a network of pipes, then possibly transferred to a storage tank or further processed.
Sous Vide
The transport sous vide, or negative transport, is the process of using compressed air to "aspirate" a bulk material through a pipeline. This method is useful for applications where contamination is a concern.

In a transport sous vide system, a compressor or supercharger is typically placed at the end of the process. One of the benefits of this method is that there is no contact between the compressed air and the material being transported, which means there is no contamination.
The distance that can be covered by this method is limited, but the product is not exposed to the heat generated by the air compression process.
La Poste France
La Poste France was a pioneer in pneumatic systems, developing a massive network of tubes in Paris from 1866 to 1984. This network was used for both postal and administrative purposes.
The first pneumatic tube was created in 1867 to connect the telegraph stations in Paris. It was a unidirectional circuit that linked the centers of the telegraph on the Place de la Bourse and the 103 rue de Grenelle.
By 1879, the system was opened to the public, leading to a significant expansion of the network. Over 450 km of tubes were installed, connecting more than 130 post offices in Paris and the neighboring town of Neuilly.
The pneumatic system was also used for administrative purposes, with a separate network connecting the two chambers of Parliament, key ministries, and government services from 1881 to 1987.
Other French cities followed Paris's lead, with Algiers introducing a similar system in 1910, Marseille in 1938, and Lyon later on.
Powder Industriel Dense

Powder Industriel Dense is a type of pneumatic system used for transporting powdery materials in a dense phase. This method is particularly useful for transporting abrasive materials over long distances.
The dense phase pneumatic system is designed to transport powders, granules, and bulk materials without causing attrition or demixing. It's a continuous and confined process that allows for precise control over the material being transported.
One of the key benefits of dense phase pneumatic systems is that they don't produce attrition or demixing of the powders being transported. This makes them ideal for applications where material quality is critical.
The system consists of a pump that aspirates the powders into a cyclone separator, where the material is separated from the air. The separated material is then collected in a receiver filter or cyclonic separator.
Dense phase pneumatic systems are commonly used in industries such as pharmaceuticals, food processing, and chemical manufacturing. They offer a high degree of precision and control over the material being transported, making them an essential tool for many industrial processes.

The system can be used to transport powders from various sources, including silos, big bags, and containers. It's also capable of preloading powders or granules from containers or big bags using canes.

Pneumatic System Basics
Pneumatic systems have been around for a while, originally designed to send packages and letters within a building using air pressure. They've since evolved to meet the needs of businesses and institutions.
The basic principle of pneumatic systems is simple: they use a network of tubes where air compression and suction are used to transport capsules containing important items to a desired location within a facility. The capsules are stopped by an air cushion and transition smoothly to the receiving bin at the station.
The tubing is typically made of steel or PVC, depending on the type of pneumatic system needed, the desired technology, and the volume of transactions expected daily.

In the past, communication methods have become more advanced, but pneumatic systems continue to be important for many industries. They remain a cost-effective way for businesses to move objects over long distances efficiently.
In hospitals, nurses need to deliver blood samples to the lab for testing. In commercial spaces, cashiers send money to the safe after work. Manufacturers also send quality control samples to their lab. Using a pneumatic tube system can save time, allow staff to focus on more critical tasks, and be more profitable for business owners.
Pneumatic systems have come a long way, with various models available, such as multilane, point-to-point, and single-line systems, each offering unique benefits and roles.
