The ROTOSTAIN is a rotary type spraying machine specifically designed for the application of any type of water or solvent based stain on flat or moulded panels. The large number of guns engaged in the operation allow for fine atomization and reduced application per gun. The final result is superior uniformity and colour consistency. The spraying machine is suitable use as a single machine with simple drying or it can be inserted in lines for more complex processing. Panel feeding is by a continuous belt CFB, which allows the recovery and reuse of the applied paint product, a patented CEFLA system, while the machine is conceived in order to allow great ease in use.
