Micro Bell Mark3
Introducing our lighter, smaller sized model
The Micro Bell mk3: Ransburg's bell type coating system with superior atomization and excellent coating efficiency.
Features
- Small size, light weight
A compact design that incorporates our newly developed small size air bearing motor and a small size trigger / dump valve. - Small size air bearing motor for superior durability and high speed rotation
The newly developed small size air bearing motor which produces a stabilized maximum high rotation speed of 60krpm has superior durability, making highly uniform atomization possible not only for general industryuse paints but also high solids, resulting in excellent transfer efficiency. - Fast color change washing and elimination of paint loss
By positioning the newly designed small size valve very close to the bell cup we have been able to make the length of the paint passage that needs to be flushed when changing colors as short as possible thus making flushing easy and keeping paint loss to a minimum. - Highly safe cascade specification
By adopting a built-in type cascade that does not need the high voltage cable to be pulled, pulling of the low voltage cable has been made easier, holding down residual charge and increasing safety. - The RPI high voltage controller raises the level of safety even higher
Thanks to overload malfunction detection functions (OL) such as the Absolute sensitivity detection function and di/dt sensitivity detection, as well malfunction detection functions (WT) such as the Low voltage cable cut detection and HV transformer over current detection function, high voltage is shut down immediately when a malfunction occurs, resulting in paint application with a high level of safety.

System Structure
The bell,s outside connecting piping and wiring consists 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 washing. The electrical system controls and supplies electricity from the high voltage controller RPI-200GIIDS 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.
