The RW250/E external protein skimmers have been designed for skimming proteins and other organic substances in medium and large marine aquaria up to 5000 litres.
They are supplied with 1, 2 or 3 powerful air production pumps.
Water circulation through the skimmer is provided by another pump (supplied on request) which can be regulated as required (skimming capability of any skimmer is in direct relation to the contact time between water and air inside the contact chamber).
The check valve placed on the external discharge tube can regulate internal water level.
The external discharge tube is also provided with another check valve for emptying the skimmer and for periodically cleaning dirt particles from the bottom of the skimmer.
Special silicon adapters between the tubes and the skimmer body ensure a long life and exceptional strength compared with usual sealing systems. The RW250/500 internal skimmer can be completely disassembled for cleaning.
The foam collection cup is specially shaped to ensure perfect skimming capacity even at low protein concentrations.
The foam collection cup has a direct foam-discharge tube and can be completely disassembled for cleaning.
