Festo has expanded its vacuum generation solutions to include a multistage generator and a multistage cartridge for porous materials, such as paper and corrugated board. The OVPN multistage vacuum generator and the OASP vacuum generator cartridge are suitable for such applications as overhead palletizing, case erecting, and bag feeding.
The OVPN and OASP meet the increasing demand for high suction flow rate in vacuum generation. A medium-sized single-stage vacuum generator, for example, has a suction flow rate of about 100 liters per minute (l/min). On the other hand, the new OVPN multistage generator’s suction flow rate ranges from 245 l/min to 960 l/min, depending on the model. The multistage OASP cartridge, which can be mounted directly on a suction cup for minimum evacuation times or used with the OVPN, has a suction flow rate range of 160 l/min to 245 l/min, depending on the model.
The OVPN nozzle technology creates high initial suction flow while optimizing air consumption. Thanks to an integrated open silencer, the OVPN operates at lower noise levels. OVPN is an ultra-lightweight component that can be used for centralized or decentralized vacuum generation.
The OSAP generator cartridge is offered in both a two- or three-stage design, with the three-stage option giving the highest suction flow rate at 245 l/min. The OSAP is available as a simple generator cartridge or with a retaining cap and integrated silencer. Like the OVPN, the OASP is both lightweight and compact.
