SUNSUN HW-604B External Filter (HW-604B)

SUNSUN HW-604B External Filter

The HW-604B / EW-604B external filter is a high-performance solution for aquariums up to 0.8 m in length, helping to keep the water clean and healthy while operating quietly and reliably. The 14 W pump provides a flow rate of up to 800 l/h, and the maximum head of 1.5 m ensures efficient water circulation in the tank. The compact design, measuring 230 × 195 × 365 mm, houses a complete filtration system that effectively supports daily aquarium maintenance.

Multi-stage filtration for better water quality

Inside the filter is a spacious bucket equipped with a set of filter media arranged between two filter plates. The set includes four types of sponge inserts with different structures—a thick black sponge, a medium-thick yellow sponge, a thin blue sponge, and a white foam insert. This design effectively traps contaminants and helps maintain water clarity. An additional advantage is the leak-proof construction featuring a rubber lid gasket and four sturdy latches that ensure the filter closes securely.

Complete set and convenient operation

The HW-604B model comes with a comprehensive set of accessories needed for installation and setup. Two 1.5-meter flexible hoses, inlet and outlet fittings, a height-adjustable spray bar, and numerous mounts and suction cups make it easy to adapt the system to your aquarium. Adjustable valves allow you to control water flow, and the well-thought-out design makes maintenance and cleaning of the filter cartridges easy. This makes the filter convenient to use both during daily operation and periodic maintenance.
