PROFIT units with paint supply containers are ideal for repairs and touch-up work with only moderate consumption of material. A closed flushing agent chamber separates air motor and fluid pump. The flushing material prevents encrustations of paint on the piston rod and with its lubricating effect protects the seals. Double-action pump with fixed, spring loaded seals. Exceptionally long lifetime due to the hard chromated double piston, hard metal valve plates and stainless steel valve balls. Double filter system (suction and high pressure filter) for trouble free operation.
