Piab vacuum conveyors increase productivity and reduce costs by automating production processes. They fulfil strict industry requirements with certifications according to FDA, EC Regulation 1935/2004, EC Regulation 10/2011, ATEX dust and ATEX gas.

Efficient maintenance and cleaning

Switching between different powder materials is quick and easy. Piab vacuum conveyors require minimal maintenance and cleaning, contributing to higher productivity and lower costs.

Flexibility and easy integration

Piab piFLOW® conveyors integrate seamlessly into existing systems or new production lines and allow for easy customisation of layout. Mobile racks enable flexible use across production lines.

Versatile use and high productivity

Piab conveyor systems make handling bulk materials easier thanks to their compact, modular design. They can handle powders, granules or particles with capacities of up to 10 tonnes per hour.

Energy efficiency and durability

Piabs offers ejector-driven vacuum generation based on COAX® technology, which ensures energy-efficient vacuum production, we also offer mechanical pumps when the task requires it. Piab builds each vacuum conveyor in durable materials with a focus on longevity and offers a 5-year warranty.

The right solutions

We help create high productivity using modern pneumatic conveying solutions

Description:

The conveying of bulk materials in the production process can now be automated in virtually all cases. A number of pneumatic transport systems are now available for use according to the respective bulk material, the nature of the task and the available space. In principle, pneumatic transport systems are differentiated into underpressure and overpressure. A combination of these systems is also possible. Powders, granules and many other dry bulk materials can be transferred through closed pipelines using a pressure differential. Pneumatic conveying systems are designed to use this pressure difference to move bulk materials from one process area to another cost-effectively in the food and beverage, pharmaceutical and chemical industries. How does the pneumatic conveyor work? Pneumatic conveyors either work with positive pressure when bulk materials are blown by the equipment from one point to another. Vacuum conveyors on the other hand are pneumatic conveyors that work with vacuum. These systems consist of four basic elements: a vacuum source, a material feeding device, a conveying line and a filter-system.
an air filter system

Negative pressure: Vacuum transport

Vacuum conveying systems offer clear advantages when conveying products from multiple infeed points to a single discharge location. Product channeling is extremely simple and dust-free due to the absence of overpressure. Bulk material is conveyed from one infeed point at a time through pipes or hoses to a vacuum conveyor. The vacuum suction stops, and the bulk material is now collected in the vacuum conveyor. The bottom hatch of the vacuum conveyor opens, and a filter blast is activated to clean the built-in filters. The bulk material falls out through the fully open bottom hatch and into the customer's receiving container, which can be a mixer/blender, sifter, sack, or packaging machine. PIAB system is dustproof and is a simple and safe process.

Positive Pressure Conveying

Pneumatic conveying (positive pressure conveying) is ideal for transporting products from a central source to multiple destinations over extended distances. Because the product is conveyed against the resistance of air, additional safety valves and pressure vessels are necessary to ensure safe and efficient operation.

Dilute-phase or Dense-phase

The selection between dilute-phase (10-30% vacuum) and dense-phase conveying (40-70% vacuum) depends on the properties of the bulk material being conveyed and the specific requirements of the application. Dilute-phase transport is typically used for materials that are easily fluidized and have good flow characteristics. Dense-phase transport is more suitable for materials that are difficult to fluidize or are abrasive. We offer a range of pneumatic conveying systems that can be tailored to meet the specific needs of each application. In many cases, semi-dense phase transport, which is a combination of dilute-phase and dense-phase transport, is the most effective solution.

Vacuum conveying - Flexible and efficient for many industrial applications

Easy to use

Why choose a pneumatic conveyor with vacuum?

→Easy to clean and disinfect:

Automatic filter cleaning prevents the filters from clogging and help extend the lifetime of the filters. A separate filter system is also made, so that the cyclone can be cleaned very quickly, without having to include the filter in the cleaning process. All our parts are designed for easy cleaning and can be taken apart without tools. Clamping rings hold our modules together.

→Efficient and easy to automate:

It can transport from 0.1 tonnes - 15 tonnes per hour, with installations in EX areas. You can choose to use compressed air driven vacuum pumps for the smaller tasks and mechanical vacuum pumps for the slightly larger systems. We offer cyclones and vacuum conveyors in different designs depending on the requirements. All steel is stainless and can be supplied from 316L acid-resistant polished steel to 304L rolled stainless steel. We have standard controls in pneumatic versions for EX areas, and there are standard PLC controls. Or we have our simple signal box so you can easily control our units from an external controller that is already in the factory. Everything is easy and simple. Everything is with the necessary documentation and 3d cad drawings.

→Reduce product scrap and pollution:

When you use a vacuum conveyor system from Provak & Piab, you work with a closed system where no material will be mixed in and no product will lie in the surrounding environment. It is also a very gentle way of transporting a product, which means that the product will remain intact during the entire transport process and will not be damaged. The speed is adjusted depending on the fragility of the product.

→Safe working environment:

When compared to mechanical transport systems such as screw and belt conveyors, another important advantage of vacuum transport is a dust-free working environment. Since PIAB vacuum transport is a closed system with vacuum, you will be able to improve the work environment, and it will also give you the ability to handle powder material that is dangerous.

→Minimal maintenance:

Piab's vacuum conveyors have no moving parts that need to be lubricated or maintained. This provides a great advantage as service and maintenance costs are kept at a very low level without the need to compromise on the reliability of the system. You can disassemble the carrier without the use of tools. The pump unit is designed as a separate module that can be easily removed for cleaning, resulting in reduced downtime.

→Space saving:

Vacuum conveyors has a very small footprint, as Pneumatic conveyors can be mounted just below the ceiling and take up very little space compared to a mechanical conveyor. The transport pipe or transport hose can run vertically from the suction point, mounted on the wall or ceiling. The hose is normally mounted level with the outlet point and therefore not in conflict with other equipment. This means that the floor space can be used in a more cost-effective way. Furthermore, if the production layout needs to be changed in the future, where e.g. new equipment will be added, a vacuum conveyor will fit the new layout without modification or expensive investment.
