In-line and mini ejectors:
These types of vacuum generators are single-chamber ejectors having a vacuum nozzle.
They are installed either directly in the hose line or directly at the suction cup or solenoid valves. Their air consumption values range from ~ 10 l/min. up to about 100 l/min.
Products with expandable options are also available (e.g. EMI models: Blow-off feature for short cycle times, vacuum switch connection and silencer options).
These include the single-chamber ejectors of the models EKP, EKPP and EMM, which provide add-on features such as vacuum and blow-off control.
They are practically maintenance-free as a result of the dirt-proof design that does not use any filter. Moreover, the intelligent pressure control saves up to 50 % of compressed air or energy costs compared to other models available in the market without having to make any compromises. The EMM model is suitable for block assembly.
Multi-chamber ejectors have several ejector nozzles connected one after another. As a result, they need up to 3.5 times less compressed air compared to single-chamber ejectors.
They provide an economical alternative particularly for high values of air consumption and are used for large volume flows and high vacuum levels.
They are used for handling air-permeable and porous materials (e.g. paperboard containers, wooden fiber boards and insulating materials) having extremely high air requirement.
Heavy-duty ejectors are the robust vacuum generators for harsh working conditions. They are insensitive to fluctuations in the compressed air network (43.5-87.0 psi). Their square design facilitates space-conserving installation of ejector blocks.
Partially available with the blow-off feature, with air consumption values up to about 100 l/min.
