Type PKU
The Type PKU Filter Nozzle by KSH Germany is designed for enhanced backwash control. A float inside the air-cushion tube reduces flow during backwashing to improve regeneration agent distribution and automatically reopens for filtration. Available exclusively in New Zealand from Absorb NZ.
