SUNSUN External aquarium filter 2000 l/h 45W white HW-704A

The SUNSUN HW-704A is an external aquarium filter designed for freshwater and saltwater tanks of up to around 1000 litres. With a flow rate of 2000 l/h and a rated power of 45 W, it keeps water circulating efficiently and supports good water quality. Rubber vibration dampers help keep operating noise low.

The filter uses a four-stage filtration system. Filter sponges, filter wool, ceramic rings and bio balls remove coarse debris and suspended particles, while the biological media give beneficial bacteria a large surface to colonise and break down harmful substances. A pre-filter catches larger dirt before it reaches the main media, extending their service life. The set includes all of these filter materials.

The hose connections rotate through 360 degrees, making installation easier even in tight spaces. A multifunction valve with quick connectors lets you disconnect the hoses without draining the filter, and a hand pump helps prime it before start-up. The pump has a ceramic shaft and a maximum lift height of 2.5 m.
