Cartridge Multi Stage Vacuum Generator

Multi-Stage Vacuum Generators for Centralized Vacuum Systems & High Flow Applications

The Vacuforce VTM Series multi-stage vacuum generators are designed for applications requiring high vacuum flow, exceptional compressed air efficiency and quiet operation. Utilizing advanced three-stage venturi technology, these vacuum generators produce significantly greater vacuum flow compared to conventional single-stage venturi designs while consuming less compressed air per unit of vacuum generated.

VTM vacuum generators are commonly used in centralized vacuum systems, large vacuum cup arrays, carton handling equipment, palletizing systems, vacuum grippers, woodworking machinery and other industrial automation applications where high vacuum flow is required. Their performance often allows them to replace traditional dry running rotary vane vacuum pumps while eliminating many maintenance concerns associated with mechanical vacuum pumps.

What Is a Multi-Stage Vacuum Generator?

A multi-stage vacuum generator uses multiple venturi stages working together to increase vacuum flow and improve compressed air efficiency. Unlike single-stage venturi generators that rely on a single nozzle, multi-stage generators use several nozzles arranged in sequence to maximize vacuum production.

This design generates higher vacuum flow rates while reducing compressed air consumption, making multi-stage technology ideal for applications involving porous products, multiple suction cups and centralized vacuum distribution systems.

Why Choose Multi-Stage Venturi Technology?

• Higher Vacuum Flow: Generates significantly more vacuum flow than comparable single-stage designs.
• Improved Air Efficiency: More vacuum generated per SCFM of compressed air consumed.
• Faster Evacuation Times: Rapid vacuum buildup for improved machine cycle times.
• Ideal for Multiple Vacuum Cups: Suitable for large vacuum grippers and vacuum manifolds.
• Centralized Vacuum Capability: Supports larger vacuum distribution systems.
• Reduced Maintenance: No moving parts to wear or service.

Centralized Vacuum Systems

Many automation systems use a centralized vacuum source to supply multiple vacuum cups, grippers or workstations. These systems require higher vacuum flow capacities than can often be achieved using small point-of-use venturi generators.

The VTM Series is specifically designed for these applications, providing the vacuum flow required for large vacuum manifolds, palletizing systems, carton handling equipment and vacuum tooling with numerous suction cups.

Can a Multi-Stage Generator Replace a Vacuum Pump?

In many applications, yes. The VTM Series is frequently used as an alternative to dry running rotary vane vacuum pumps, particularly where users wish to eliminate mechanical maintenance, lubrication requirements and pump wear components.

Because the VTM generator contains no moving parts, reliability is extremely high and maintenance requirements are minimal. Application review is recommended to determine suitability for specific vacuum pump replacement projects.

Energy Saving Vacuum Systems

The VTM Series can be combined with the Vacuforce ESK Energy Saving Kit to further reduce compressed air consumption. Energy saving systems automatically stop compressed air flow once the desired vacuum level has been achieved and restart only when vacuum drops below the programmed threshold.

This can significantly reduce operating costs in systems that maintain vacuum for extended periods of time.
