Delivery options to:
Choose countryThe SUNSUN HW-703A is an external filter for freshwater and saltwater aquariums up to 600 L. It provides a water flow rate of 1 400 L/h with a 30 W power rating and can be positioned under or beside the aquarium.
Three-stage filtration
The system supports mechanical, biological and chemical filtration. Sponges and filter fleece trap larger contaminants during mechanical filtration, reducing suspended particles in the water. An additional pre-filter catches coarse debris and helps extend the service life of the other filter media. Filter media are not included and must be purchased separately.
Installation and maintenance
- Manual priming pump: fills the system before startup.
- Multifunction valve: regulates water flow and uses a quick-connect fitting to disconnect hoses without draining them, while helping prevent uncontrolled leaks.
- Flexible hose routing: 360° rotating hose connections and 1.8 m hoses help with positioning.
- Vibration reduction: a ceramic pump shaft and rubber feet help reduce operating noise.
The set includes the external filter and connection hoses. The filter operates from a 220–240 V, 50 Hz mains supply.
