Product Details:

The latest electrostatic rotary atomizer provides the state-of-the-art performance in robotic application including superior finishing quality in metallic paint coating.

Supreme finishing quality is achieved in various coating conditions by combining suitable shaping air technology and 4 types of the bell cups.


Rotary atomization spray technology Ransburg has accumulated over the past half century.

Among the electrostatic applicators that have many benefits such as high transfer efficiency, VOC reduction and reduction of paint usage, rotary atomizers have even better transfer efficiency than guns and achieve excellent finishing quality.

Over the past half century of the history of rotary atomization technology, we have made continual progress in a variety of areas such as spray technology including compact sized / durable / capable of high-speed operation air motor, variable pattern function by the shaping air technology, improvement of paints and safety technology.

The Mighty Robot Bell 21 is the latest bell type electrostatic applicator that is more compact and lighter weight than the previous model and responds to a wide range of user needs for application consisting of a variety of paints including metallic paints and various sized workpieces.



  • Supports the spray robots of a variety of companies.By changing the rear adapter, the Mighty Robot Bell can be mounted to the robots of a variety of companies.
  • A compact air bearing motor with excellent durability and high-speed rotation performance.
    The newly developed compact air bearing motor that produces a stable rotation with 60,000 rpm at the maximum speed is highly durable and provides excellent rotation performance, and delivers high transfer efficiency not only for general industrial paints but for high solid paints as well by achieving high atomization with high uniformity.
  • Easily sprays all the surfaces of workpieces.
    It easily sprays the front surfaces, side surfaces, and inside surfaces of workpiece by setting an angle from the spray robot´s mounting point to the tip.
  • Cascade excels in safety.
    Adopting a built-in cascade that does not require the routing of high voltage cable allows easier routing of low voltage cable, and improves safety by suppressing residual electrical charges.
  • Besides RPI type controller, advanced model RIC type high voltage controller is available
    For ensuring safety RIC type high voltage controller that offers a superior level of safety is optionally available along with RPI type high voltage controller that immediately shuts off high voltage supply when detecting an error such as overcurrent and voltage cable breakage.
