This is a conveyor widely used in the industry where food grade quality is a demand. Typical applications are: Food grade applications or powder and granules transfer or mill/sieve/mixer/blender filling or tablet/fragile transfer or big bag loading and unloading or applications in explosive atmosphere.
Yes they are.
Depending on the filter type there are different recommendations. Please read the cleaning instructions in the corresponding manual for the vacuum conveyor.
Yes it can, a level sensor including the electric/pneumatic valve will be integrated for it. 110VAC or 24VDC are integrated.
The unit has a pneumatic control which controls the suction and discharge time.
It can also be w/o control, in that case the end user will need to provide the sequence of operation – PLC control.
El/pneumatic valve unit can be provided (to convert the electrical signal to a pneumatic output to signal the Piab).
Yes, it is all metric tubing and hardware.
Start the Piab control via a pneumatic On/Off valve.
The vacuum pump starts and at the same time the bottom flap/door closes, the back pulse container (located inside the top part of the Conveyor) charges with compressed air (line pressure). The suction time begins (adjustable to 1-30 seconds via the pneumatic timer).
When the suction time times out, the control goes into a discharge cycle (adjustable to 1-30 seconds), the vacuum pump will stop, the bottom flap/door opens and the back pulse will clean the filter. And after that it will re-start until the unit is shut off.

We can deliver these vacuum conveyor units in 2-4 weeks after receipt of order.
Ra 0.6 µm or better.
We have different ones for different needs:
They can convey products between fine powder to plastic granules and from free flowing material to non-free flowing dry material.
They definitely can. Please see our success stories.
Yes. Piab has experience of conveying a large variety of tablets and capsules without damage. Please contact us for detailed information.
No it can’t. Normal procedure is to dose before or after conveying.
No we can’t. It’s extremely difficult to control the amount of liquid coming in the vacuum conveyor.
Yes, up to 8-10 meters without accessories/pipe emptying solution. With a pipe emptying solution up to about 25 meters.
For piFLOW®p we can supply this documentation. It is a template that shall be filled in during start up and with the help of the manual that comes with the shipment.
No, the vacuum conveyors use only compressed air. Even our control systems are pneumatic.
Piab offers a warranty to distributors, integrators and users of Piab products worldwide as per the following definitions:
In the manual for your vacuum conveyor there is a section about troubleshooting. You are also welcome to contact your nearest Piab office for further help.
0 – 50 meters if the conveying length does not include a vertical lift more than 5m and the product density is between 0.5-1.0kg.
By having the right mix of air and conveyed product. This is achieved from where the Piab vacuum conveyor draws the material with the help of our feeding point accessories. Please also read our white paper on segregation and contact any Piab company for further information.
No they are not, only for under pressure.
Not if instructions in the manual are followed. All Piab vacuum conveyors have a grounding point and can be sent with ATEX dust approval.
Tools are not really needed for assembly/de-assembly. For more detailed information, please look in the manual for your vacuum conveyor or in our YouTube channel.
From about 0.1 ton/h to about 15 ton/h.
Please use the application configurator. You are also welcome to contact Piab or a Piab partner for details.
With regular maintenance, the vacuum conveyor unit will do the job for years to come.
If the compressed air is dirty/has fluid in it, the filter can be clogged as well as the ejectors and the timers. Water in the air line is not optimal.
Consult the manual for troubleshooting if you would encounter anything unusual.
