The SUNSUN HW-504A is an external canister filter designed for aquariums with a capacity of 30 to 200 liters, providing effective, multi-stage water filtration. With a flow rate of 1000 l/h, a filter capacity of 5 liters, and four filter media baskets, it effectively removes impurities and waste, helping to maintain clear water and stable conditions in the aquarium. The separate pump and filter design makes it easy to use, and the compact dimensions of 190 × 155 × 320 mm ensure the unit doesn’t take up much space.
The filter is equipped with four filter baskets, allowing you to create an efficient mechanical, biological, and chemical filtration system. The user can independently select and arrange the filter media according to the tank’s requirements. The design is suitable for both freshwater and saltwater aquariums, making the HW-504A ideal for various aquarium setups.
The use of an external flow pump placed directly in the aquarium reduces operating noise, ensuring a high level of user comfort. The filter is easy to install and maintain, and its design does not require pre-filling with water before startup. Additionally, the unit is equipped with inlet and outlet valves that allow for flow regulation or complete shutdown of the water circuit during maintenance.
The kit includes all the components necessary to start the filter. The included hoses of various diameters—18 mm (3/4 inch) for the inlet and 12 mm (1/2 inch) for the outlet—along with the rain shower, valves, and connectors allow you to quickly prepare the system for operation. The user can also choose how to drain water into the aquarium, using either a classic outlet or a rain shower head.
The HW-504A stands out for its safe and reliable construction, designed for long-term use. The maximum water lift is 1.3 m, ensuring efficient water circulation in the aquarium. Its aesthetic design, easy access to the filter baskets, and practical clip-lock system make maintenance quick and convenient.
