Get An In-Depth Knowledge About Pneumatic Tube Transport Systems

Thousands of factories, hospitals, department stores, banks, and various other places depends on pneumatic tube-based transport mechanism to transport cash packets, medicines, and other kinds of small items with great security, efficiency and speed. In this article, we will take a closer look at their working process.

What is the Pneumatic Transport System?

Pneumatic transport systems are also popularly called as PTT, air transport, airlift, air tubes, pneumatic transit systems and Lamson tubes. Pneumatic tube systems are made up of stations that helps in sending as well as receiving a tube network through which the carriers get transported with air. These new transport systems are fully automated and provide a trusted medium to transport logistics.

How this system makes transportation of cash hassle free, quick and reliable?

If you wish to send cash on an urgent basis and securely to any other part of the building then you can consider using a pneumatic transit canister for this job. This canister is made using a sturdy plastic named polycarbonate, which safeguards whatever is packed inside.

When the tube of this system gets loaded, then put a cap on one of its ends and keeps it inside the pneumatic transport tube. When the tube is blown or sucked, it reaches to the destination five to six times quicker than any other type of messenger.

Working of a pneumatic transport system

A tube makes a connection between the sending station and the receiving station. The air compressor located at the destination sucks or blows air. When the air is sucked, then it pulls the canister along with the tube in its direction. When the air gets blown, then the canisters are pushed in the reverse direction.

Similar to a vacuum cleaner, the function of a pneumatic tube-based system is restricted by the suction ability of the electric motor. Due to this reason, there is a limit on what these tubes can carry, how fast they can carry and for how much distance they can carry.

A general pneumatic canister has a size of about 5 to 15cm i.e., two to six inches in diameter. It has around 20cm to 30cm length and is made up of a hardened plastic like polycarbonate. These canisters have rubbery bumpers located at its ends that deliver a good quality air seal. It also helps in the prevention of noise as it travels down through the tubes.

Most of the pneumatic tube-based systems are designed to be simple networks that are capable of linking one receiver to various senders and vice-versa. Nowadays you can find advanced and powerful computer-controlled pneumatic systems that can connect several sending stations to several receiving stations and can transfer contents in various types of complicated ways.

A large sized pneumatic system is the one that can have nearly 500 sending stations and receiving stations, and a handful of transfer units, compressor and blower units to offer remarkable pneumatic power.


Pneumatic transport systems are a safe and reliable way to transport all your valuable and critical data between two separate areas.  Looking at their advantages, many businesses consider these systems for their varying needs of material transportation.
