Tunze Overflow Box
Overflow for supplementary installation with surface and bottom suction up to about 1,200l/h (320USgal./h). No boreholes in the glass required, and thus it can be retro-fitted easily. Even after an interruption of the recirculation pump, it will restart the siphon automatically. With additional U pipe 1001.740 (cf. Turbelle filter accessories), a throughput of 1,500 l/h (400 USgal./h) is possible. Water outlet ø40 mm (1.6").
For easy installation and quiet operation, we recommend the use of overflow hose set 1075/2.
