Add an electrostatic effect To achieve maximum transfer efficiency, an electrostatic effect is added to the ProBell. The charge is generated by the 60/100KV electrostatic power supply within the rotary atomizer. The bell cup itself is charged, and the charge is transferred to the paint as it flows through the bell cup. The charged paint droplets are attracted by the grounded target. An electrostatic effect provides excellent wrap- around to the back of the part. Thanks to this electrostatic effect, the ProBell rotary atomizer produces a superior finish with an extremely high transfer efficiency. Opt for modularity and scalability A key feature of the ProBell Applicator is its modular, scalable design, which gives users the flexibility to start small with one controller and work their way up to more, or install a complete system all at once. This modularity allows users to meet their production needs and budget. The ProBell incorporates up to four controllers: electrostatic controller; speed controller; electronic air controller and a system logic controller that is a user-friendly interface for intuitive management of spray parameters. The ProBell Applicator is offered in configurations for a fixed mount, reciprocator, solid wrist robot and hollow wrist robot. The hollow wrist robot configuration allows users to remove the 56 JUNE 2019 applicator from the robot without removing all the hoses, making it more convenient for maintenance. The removable shroud also facilitates maintenance. The turbine assembly is a proven, durable design and the air bearing has no parts to wear out. In addition to delivering mounting compatibility, the ProBell Applicator is lightweight and compact, which allows for lower payload robots or reciprocators, and allows spraying in confined spaces. In short, the applicator’s unique, scalable design paired with superior quality, high transfer efficiency and precision spraying makes it easy to develop solutions to fit the specific requirements of each installation. Ask for advice Paint lines have never been easier or less expensive to automate. Automation of paint lines should be approached as a long-term strategic decision and a great opportunity to redesign your process and explore your entire value stream. For more details on robotic painting in general or the ProBell Rotary Applicator in particular, don’t hesitate to ask the Graco specialists for advice.
