Festo introduces multistage vacuum generator and cartridge for packaging automation
November 14, 2024 By P&PC Staff
Festo has expanded its vacuum generation solutions to include a multistage generator and a multistage cartridge. The OVPN multistage vacuum generator and the OASP vacuum generator cartridge are ideal for such applications as overhead palletizing, case erecting and bag feeding. These new pneumatic vacuum components are designed to offer high performance on porous materials such as paper and corrugated board.
The OVPN and OASP reportedly meet the increasing demand for high suction flow rate in vacuum generation. 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.
According to Festo, the OVPN nozzle technology creates high initial suction flow while optimizing air consumption leading to maximum energy efficiency and sustainable operations. Featuring 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 reportedly 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.
The vacuum suction flow of these units is generated through multiple connected Venturi nozzles. Multistage vacuum generators are primarily used in factory automation, particularly in packaging machines. With high flow rate and efficiency enhancements built in, OVPN and OASP can optimize workflow and increase productivity.
Festo reportedly offers a comprehensive line of vacuum generators based on the Venturi principle. Festo vacuum generators range in suction flow rates from 6.2 l/min to 960 l/min. Festo vacuum suction cups and suction grippers link the vacuum generator and the workpiece and are an important part of the vacuum system. They are available in a variety of materials (nitrile rubber, polyurethane, silicone, and natural rubber) and in different shapes (universal, flat, bellows, and special suction grippers).
