Vacuum Belt Conveyors


Vacuum Conveyors

When your products or components are small, lightweight and moving at a steady speed, you need a transfer solution that will keep things on track, literally. Vacuum conveyors use suction to hold items of all sizes in place as they move along, up and down the belt.

Vacuum Belt Conveyors

Among all of your conveying options, vacuum belt conveyors are ideal when you’re working with small, flat parts and other lightweight, thin materials. Like all Dorner conveyor solutions, our vacuum belt conveyors come in a variety of configurations, enabling you to optimize your physical space while keeping your production and budget needs in mind.

Some models handle varying elevations, enabling you to fit them into tight spaces. Additionally, a range of add-ons and accessories help meet your product and process needs.

How Do Vacuum Conveyors Work?

Vacuum conveyors work by creating suction that keeps items flat on the belt surface. For example, a vacuum conveyor belt could prevent sheets of paper, plastic parts, cardboard, leaflets, small pouches, or empty plastic packaging from flying away as they move down the line.

This suction power is created by an internal vacuum pump that pulls air flows through perforations within the belt. This creates a seal, keeping items intact.

Each vacuum conveyor is custom designed based on the customer’s application and product. Dorner’s engineers work with our customers to figure out the proper belt and hole spacing, pattern and size.

Vacuum conveyors use a custom bed plate with a vacuum chamber to focus the suction on the proper place. Ports are custom-drilled into the conveyor frame for the vacuum. The number of ports drilled depends on our customers’ needs.

There is no vacuum on the conveyor tails. The suction prevents any slipping or sliding of the product while the product can still be easily lifted away from the belt.

Dorner can provide the blower assembly or our customers can provide their own.
