Piab Vacuum Conveyors

Piab’s range of vacuum conveyors includes versions that are fully dust controlled and FDA and ATEX approved. The conveyors enable transfer of product from bulk bags or feed stations to hoppers, blenders or directly into processing machines.

The conveyors can handle powders, grain, tablets, noodles while containing any dust and without causing damage to the product.

The conveyor body is either 316 or 304 stainless depending on the application. The vacuum can either be created by Piab COAX vacuum cartridges or a vacuum pump depending on the flow required and hazard rating.

When the vacuum is turned on the product is conveyed from the feed station through pipework to a container in the conveyor module; a filter protects the pump and the surrounding area from dust and small particles.

After an adjustable time delay, the conveying is stopped and a flap valve is opened to discharge the product. At the same time an air shock is activated and the compressed air cleans the filter of dust and small particles.

The flap valve then closes and the conveying starts again.

Piab vacuum conveyors have few moving parts, meaning that the service and maintenance are kept to a minimum without needing to compromise on the reliability of the system.

Being an enclosed system there is no possibility of contamination of product.
