How to inspect and maintain the EcoBell3 rotary atomizer on a Durr paint system
Bell cup wear or bearing failure on the EcoBell3 rotary atomizer causes paint film defects and uneven spray pattern. Measure bell cup runout and check bearing air pressure before each production run.
How to fix conveyor speed faults in a Durr EcoDryScrubber / EcoBell3 paint booth
Conveyor speed variation causes film thickness variation across the car body. Check the VFD and drive chain tension before adjusting the conveyor speed parameter.
How to manage overspray buildup in a Durr EcoDryScrubber / EcoBell3 paint booth
Excessive overspray buildup in the dry scrubber reduces air flow and degrades paint quality. Follow the limestone powder charge schedule and replace the filter trays before build-up reduces booth airflow below specification.
