If you have challenges with dust, spills, or inconsistent dosing, vacuum conveying is an effective solution. It is a form of pneumatic conveying where the material is moved using air in a closed system.
It reduces dust and waste and ensures a more stable and controlled dosing. The result is a more reliable process and a better working environment in production.
A simple process
Vacuum Conveying is a simple process – but with a great impact on operations, quality, and the working environment.
The material is automatically drawn from a feedpoint via vacuum.
The material moves through a closed pipe system – with no dust or spillage.
The material is delivered and dosed precisely into the receiving container.
The process is repeated automatically, ensuring stable operation.

Cases & Results
See how vacuum transport has eliminated dust, manual lifting, and unstable operation in production.
The choice depends on your production, materials, and operational requirements.
Here are the most typical solutions – and when they make sense.
piFLOW premium
For productions with high demands on operation, documentation, and control.
piFLOW f
When approvals and basic requirements need to be met
piFLOW fc
When there is often a need for cleaning and handling large quantities
piFLOW premium
When there are high demands with less capacity. .
The material is sucked from a feed point and transported through a closed pipe system to a container, where it
Dose-controlled. The process runs automatically in repeated cycles.
Yes. The solutions can be delivered with ATEX certification for both dust and gas, depending on your requirements.
Vacuum transport can move powder up to 50 metres. Further distances drastically reduce capacity.
We can handle almost all dry powdered materials with a maximum moisture content of 30%. If the moisture content is higher, we will need to carry out a test before we can offer our equipment.
No – PIAB vacuum conveying generally requires very little maintenance.
Here's why:
Wear parts
PIAB's vacuum conveyors are constructed with:
No rotating or mechanical parts in the material flow
The primary wear parts are seals and filters, which are easy and cheap to replace.
Reliable construction
Pneumatic operation = no motors or gears
Robust design, suitable for continuous industrial operation
Often used in the food, pharma, and chemical industries, where operational reliability is critical
Easy cleaning and inspection
Quick disassembly without special tools
Smooth surfaces and hygienic design (CIP/SIP on selected models)
Cleaning can often be done in a few minutes
Low maintenance requirements in practice
Typical maintenance consists of:
Visual inspection
Periodic inspection/replacement of filter
Check of seals during planned shutdown
Calculate total cost of ownership (TCO)
Low maintenance means:
Reduced downtime
Yes – PIAB vacuum conveyors are specifically designed for easy integration into existing equipment and processes.
It is one of their great strengths.
✅ Easy retrofit
PIAB solutions are often used for:
Upgrading manual processes
Replacement of snails, elevators or bucket handling
Automating material feed
They can typically be integrated without major changes to the layout or machinery.
✅ Flexible connections
PIAB vacuum conveyors can be connected directly to:
Bag charge
Sights
Mixer
Reactors
Tablet presses and capsule machines
Feeding and dosing equipment
Inlet/outlet can be customised in height, angle, and flange type.
✅ Simple control integration
Works pneumatically → only requires compressed air
Can be controlled via:
PLC
Digital I/O
Simple pneumatic sequences
To synchronise with existing machine sequences
✅ Minimal space and intervention
Compact units, also for tight production areas
Snakes can be carried:
Vertically
Horizontally
Around existing installations
✅ Suitable for many industries
Integration ses ofte i:
Food production (flour, sugar, spices)
Pharma (APIs, granules, tablets)
Chemicals (powder, pellets)
Plastic (granules)
With correct material selection (stainless steel, ATEX, FDA etc.).
✅ Quick implementation
In many cases, the solution:
Installed in a few days
Dries and validates quickly
Commissioned without further production downtime
In short:
PIAB vacuum conveyors are highly integrable, both mechanically and control-wise, and are often used as a flexible upgrade for existing production equipment.
Vacuum conveying is a method of transporting powders and granules in a closed pipe system using negative pressure.
It is a form of pneumatic conveying where material is moved using air instead of mechanical components. It ensures dust-free, hygienic and controlled transport in production.
The solution is typically used in food, pharmaceutical, and industrial production, where stable operation, high product quality, and minimal contamination are required – as part of an efficient powder handling solution.
Compared to mechanical transport systems such as screw and belt conveyors, vacuum transport requires less space and provides a more flexible and dust-free process.
