In a world where digital communication reigns supreme, pneumatic tube systems might initially seem like a relic from the past. However, while emails and messaging services excel at transmitting information, there are still many industries where physical items need to be transported quickly and reliably.
This is where modern pneumatic tube systems come into play. Despite their long history, they remain indispensable across various sectors. That said, alongside their clear advantages, it’s equally important to consider the potential drawbacks to make an informed decision.
What Exactly Is a Pneumatic Tube System?
A pneumatic tube system is a network of tubes through which cylindrical containers are transported using air pressure. This technology enables the fast transfer of physical items such as documents, samples, medications, or cash between different stations.
The operating principle is surprisingly simple: air is removed from the tube to create a vacuum, and a combination of negative pressure and fans propels the containers at speeds of up to 8 metres per second—with some systems reaching up to 11 metres per second.
Modern pneumatic tube systems are now equipped with computer-controlled switches and RFID transponders, allowing for precise tracking of every shipment and largely automated operations.
What Are the Advantages of a Pneumatic Tube System?
The implementation of a pneumatic tube system offers numerous benefits that go beyond simple transport. These advantages make the technology particularly valuable in industries where efficiency and security are top priorities.
Speed and Efficiency
One of the greatest advantages of pneumatic tube systems is their significant time savings. Instead of employees having to walk long distances, crucial materials can be transported within seconds. This is especially important in environments where time is critical, such as hospitals.
In a large medical facility, for example, a blood sample can be sent via a pneumatic tube system from a patient’s room to the laboratory in under a minute—a process that could easily take 10–15 minutes on foot.
Cost Savings
In the long run, a pneumatic tube system can lead to significant cost reductions. While the initial installation requires an investment, it greatly reduces the need for staff to carry out delivery tasks. In larger facilities, these savings can be substantial over time.
A simple calculation illustrates this: with 24 deliveries per day, each taking 10 minutes, around 1,000 working hours could be saved annually. At an hourly wage of €15, this equates to a yearly saving of €15,000 – a considerable reduction in operational costs.
Space-Saving and Adaptable
Modern pneumatic tube systems are space-efficient and can be seamlessly integrated into existing building structures. They can be expanded as needed, with tubes running through walls, suspended ceilings, or under floors, making them barely visible. This discreet integration is particularly attractive in environments where aesthetics matter.
The Most Common Disadvantages of Pneumatic Tube Systems
Despite their many advantages, pneumatic tube systems also come with certain limitations that should be considered when deciding whether to implement them. The impact of these drawbacks can vary depending on the intended use case.
Limited Transport Capacity
One of the most obvious disadvantages of pneumatic tube systems is the restriction on the size and weight of transported items. Most systems can only handle objects that fit into standardised containers, typically with a diameter of 5 to 20 cm and a maximum weight of around 5 kg. This limitation makes pneumatic tubes unsuitable for transporting larger objects.
In hospitals, this restriction is often less problematic, as small samples are the primary items being transported. However, in industrial settings, the weight limitation can be a more significant issue—although there are specialised systems designed to accommodate certain heavier materials.
High Initial Investment
Installing a pneumatic tube system requires a significant upfront investment. The costs vary depending on the size and complexity of the system but can easily reach tens or even hundreds of thousands of euros. This cost factor is particularly important for smaller businesses with limited budgets, making it a crucial consideration in the decision-making process.
Maintenance and Technical Issues
Like all mechanical systems, pneumatic tube networks require regular maintenance. Issues such as blockages, seal wear, or technical faults can arise. These disadvantages mean that reliable technical support must be accounted for. Routine inspections and servicing are essential to ensure the system remains operational and efficient.
Limited Flexibility for Modifications
Once installed, a pneumatic tube system is not easily reconfigured. Changes to the route layout or adding new stations can be complex and costly. This is especially problematic in environments that undergo frequent structural changes. Therefore, careful planning is essential to ensure the system meets long-term operational needs.
Minimising Pneumatic Tube System Disadvantages with the Right Partner
Despite the rise of digital communication technologies, pneumatic tube systems have maintained their relevance in specific industries where the fast and secure transport of physical items is essential. In hospitals, banks, retail stores, and industrial settings, the advantages often outweigh the drawbacks.
The decision for or against a pneumatic tube system should be based on a thorough analysis of specific requirements, the size of the facility, and a long-term cost-benefit calculation. While the disadvantages should not be overlooked, in the right applications, this technology provides an efficient, secure, and reliable solution for in-house logistics.
