Tunze overflow box 1072Our price: £100.05
TUNZE® overflow outlets with surface and bottom
suction are an ideal solution for an unpressurised
water supply below aquariums. The outlets remove
only as much water as is pumped into the aquarium:
About 50 per cent surface and 50 per cent bottom
water. On account of the opaque construction, the
units are almost maintenance-free and are ready for
connection, but they are supplied without inlet and
outlet pipes. Two outlet systems should be used in
aquariums with more than 600 litres (158.5 USgal.).
Overflow Box 1074/2 (1) for retrofit for up to a
maximum of 1,200 l/h (317 USgal./h); requires no
drillholes, and for this reason can be easily retrofitted
in every aquarium. Even after an interruption of the
recirculation pump, it will restart automatically. The
U-shaped tube (2) between the two chambers does
not require any additional ventilation as the water
velocity passes the air bubbles in the pipe into the
drain chamber (3) automatically. A minimum water
flow rate of about 300 l/h (79 USgal./h) is required..
