External Filter SUNSUN HW-603B (HW-603B)

SUNSUN HW-603B External Filter

The SUNSUN HW-603B external filter is a compact solution designed for aquariums less than 0.6 m in length or height. The unit is equipped with a 6 W pump with a flow rate of up to 400 l/h, which ensures effective water circulation and filtration. The five-stage filtration media system and a complete set of installation accessories make this filter a practical solution for maintaining clean and clear water in your aquarium.

Five-stage filtration for clean water

The HW-603B model uses vertical water flow through five consecutive filtration zones. Above the filter cartridges is a space designated for the growth of nitrifying bacteria, which support the biological balance in the aquarium. The water then passes through a blue sponge that traps sediment, a yellow sponge that captures fine particles, a black sponge that filters out colloidal residues, and a white nonwoven fabric that removes residual water discoloration. This design effectively purifies the water at various stages of filtration.

High-Performance Pump and Stable Operation

Water circulation is handled by an external JP-450G pump with a power rating of 6 W. The maximum flow rate of 400 l/h enables effective water filtration, and the head of up to 0.85 m ensures proper operation of the unit in the aquariums for which it is designed. The 12-mm connectors ensure compatibility with the included accessories and smooth water flow throughout the entire system.

Complete, ready-to-install kit

The kit includes all the basic components needed to set up the filtration system. In addition to the housing and pump, the user receives two 1.5-meter-long flexible hoses, shut-off valves with flow control, a set of inlet and outlet tubes, a multi-hole spray head, a flattened nozzle, and mounting suction cups. This makes filter installation quick and eliminates the need to purchase additional accessories.
