Pneumatic conveying systems are the most popular choice for material-handling equipment, boasting plenty of positives from their safe, user-friendly design to their ability to handle bulk material with ease. Let’s take a look at the pros and cons of pneumatic systems, with a brief explanation of their functions.
What is a pneumatic conveying system?
For anyone unfamiliar, these machines can be intimidating in text, let alone in person. Let’s break it down word by word: ‘pneumatic’ means pressurised air is used, with common examples being air brakes and door systems on buses and trains. ‘Conveying’ simply means carrying something from one place to another.
From this, we can infer that pneumatic conveying systems use pressurised air to transfer materials, specifically, bulk materials such as powders or granules. A more detailed guide with photos and diagrams can be found here.
Pros
Through the use of pressurised air, pneumatic conveyors allow for material transfer over longer distances without interfering with your current equipment. The machines are also fairly flexible with their installation, requiring little – if any – structural support and easily fitting in amongst other equipment.
Many systems can allow for a push-pull blend, using pressure differentials to convey materials efficiently. Depending on the type – pressure or vacuum – materials can be transferred at higher conveying rates, providing greater efficiency.

Pneumatic systems are also safe and low maintenance, with the safety of handlers and materials both ensured. The systems are great at keeping dust and harmful materials contained.
Cons
Whilst pneumatic conveying is highly effective for material transfer, the speed requirements of the air to enable this transfer are high. This means higher energy inputs are required, making the process more expensive depending on the material.
The potential for blockages is also increased with this system, again dependent on the materials being used. This can be avoided by taking the appropriate precautions and knowing which materials to be careful with.
The systems are only dangerous with poor handling, with most issues being avoidable with proper briefing.
