The paths externally connected and wired to the bell body consist of 3 systems; paint, air and electrical systems. The paint supply system supplies the paint, which is sucked up from the paint tank by the gear pump, to the paint valve. Paint is supplied to the applicators when this valve is turned ON. From the air control panel, the air supply system supplies the turbine air which controls bell cup rotation, the shaping air which controls the pattern and the pilot air which controls the trigger valve for the paint and the dump valve for flushing. The electrical system controls and supplies electricity from the high voltage controller via the low voltage cable to the cascade (booster) that is built into the bell unit. A built-in safety circuit automatically shuts down the high voltage system when abnormal current is detected, guaranteeing a high level of safety.
Rotary atomization spray technology Ransburg has accumulated Rotary atomization spray technology Ransburg has accumulated over the past half centuryover 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 Micro Bell 4 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.

■ 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.
■ Downsizing and weight reduction of bell body The valves mounted on the bell body are the same as the previous model (Mark 3). By making the diameter of the bell body 25mm smaller 1kg weight reduction was achieved. This reduces the load to the reciprocator and contributes to the improvement of the durability.
■ The shaping air mechanism affecting finishing quality The internal structure of the previous model was revised for better dispersibility of the shaping air to obtain uniform spray pattern. With the variable pattern type 40mm bell cap the spray pattern size is controlled by the dual shaping air mechanism depending on the various sized workpieces. This reduces overspray and leads to reduction of paint usage.
■ 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.
■ The bell cup variations support a variety of application Applicator model can be selected from 4 types of bell cups and 3 types of shaping air rings depending on user needs for application consisting of a variety of paints including metallic paints and various sized workpieces.
The dual shaping air mechanism produces suitable spray pattern for each workpiece With the dual shaping air mechanism adopted to the 40mm bell cup the pressure setting of the inner shaping air and the outer shaping air is controlled independently, which enables spray pattern size control improving film thickness distribution in the spray pattern. Adjusting the bell speed and the flow rate along with pattern size control makes spraying conditions optimum. Finishing quality of metallic and high brightness paints is greatly improved reducing the unevenness.
