Pneumatic transport

Pneumatic transport

Pneumatic conveying works with compressed air, which creates a vacuum in order to suck in air and powdered product. The product is transferred in a pipe from container A to container B.
The suction time is managed by a device called a “pneutimer”.
Pneumatic conveying is usually integrated into big bag emptying stations and hoppers.

The benefits of this system :

  • It is easy to set up
  • It is easier to clean than an Archimedean screw system for example
  • It requires low maintenance
  • It takes up little space in the installation
  • It is clean and easy to clean, which makes it a solution of choice in the pharmaceutical or food industry
  • It is simple to start up for the operator
  • It is part of a system controlled by automatism.
  • The absence of friction prevents the product from being damaged during the transfer


Pneumatic conveying works by injecting compressed air into the transfer pipe. The movement of the product is possible by suction of the air caused by the venturi effect. It is a very dustproof system.

Pneumatic conveying is often recommended for long or complicated product paths, or when several containers need to be served. This type of transport can be chosen for the filling of big bags or to quickly transfer a product from one container to another.

This system is suitable for many sectors of industry like food, chemical, or pharmaceutical. A pneumatic conveying solution is studied according to the characteristics of the product to be transferred. For example, the granulometry, abrasiveness of the product, or its fragility must be considered.

Pneumatic conveying requires only air to operate, no electricity. It is essential to have an air supply available near the installation.
This system does not require a level sensor to start up.

Before considering this system, it must be considered that a pneumatic conveying system operates with a lower flow rate than an alternative transfer solution. In addition, it consumes a lot of compressed air.
