The RBM 402 F series is the highest highest developed brushing machine in our range. It is ideally suited for professional prototyping or small batch production in modern PCB laboratories. The machines perform double side operation. Upper and lower brushing rollers are adjustable in pressure and have a digital read-out. Oscillation and transport speed are variable. The wet procession system comes together with a powerful squeeze + hot-air dryer. The "F" is indicating an integral, automatic filter system. That is urgently recommended in order to comply with German and European waste water pollution directives. These "F" machines are equipped with a 100 m filter tape (5 µm) and a waste water level control. As the tape load of filtered particles increases, the sensor will automatically start the filter transport, so that fresh filter tape is supplied.
