SUNSUN HW503 External Filter

The SunSun HW-503 external filter is a compact solution designed for aquariums with low water levels. Equipped with a 6 W pump, it delivers a flow rate of 600 l/h, effectively helping to keep the water clean and clear. Its small dimensions of 212 × 172 × 287 mm and weight of 1.9 kg make it easy to place next to the aquarium, and its compact design facilitates daily operation and maintenance. Information regarding performance, power, and dimensions is confirmed by the manufacturer’s documentation.

The HW-503 model is designed for efficient operation with low power consumption. The built-in pump ensures a constant water flow, and the multi-stage filtration system allows for gradual removal of contaminants. The filter can be used in both freshwater and saltwater aquariums, and the maximum lift height of 0.9 m ensures proper water circulation under appropriate installation conditions. The design does not include a UV lamp, making this a Non-UV version.

The unit is equipped with a practical handle and sturdy snap-on clamps that make it easy to open and close the housing during maintenance. Simple installation and a compact, portable design allow you to conveniently move the filter and quickly set it up for operation. A long 1.5 m power cord provides greater freedom during installation near the aquarium.
