SUNSUN HW-703A External Filter
The SUNSUN HW-703A is a high-performance external filter designed for aquariums with a capacity of up to 600 liters, providing a water flow rate of 1,400 L/h. Its three-stage filtration system, 30 W power rating, and compatibility with both freshwater and saltwater aquariums make it highly effective at maintaining clean and healthy water. Thanks to its compact dimensions of 258 x 258 x 440 mm, 360° rotatable hose connections, and quiet operation, the filter can be conveniently installed under or next to the aquarium.
Three-stage filtration system for better water quality
The filter uses three stages of water purification: mechanical, biological, and chemical filtration. The first stage is responsible for trapping larger contaminants using sponges and filter floss, thereby reducing the amount of suspended particles circulating in the aquarium. An additional pre-filter effectively captures coarser debris and helps extend the lifespan of the remaining filter media.
Biological support for aquarium balance
The set includes bio-balls and ceramic rings, which provide a large surface area for the growth of beneficial filter bacteria. They support the natural biological processes occurring in the tank, helping to maintain stable conditions for fish and other aquatic organisms. The biological media used are characterized by a long service life, which translates to lower operating costs.
Convenient operation and easy maintenance
The HW-703A model is equipped with a manual pump for quickly filling the system before startup. A multifunctional valve with a quick-connect fitting allows hoses to be disconnected without draining them, which significantly facilitates cleaning and servicing of the unit. Additionally, the valve allows for water flow regulation and helps protect the system against uncontrolled leaks.
Quiet operation and flexible installation
The ceramic pump shaft and rubber vibration-damping feet help reduce noise during filter operation. The 360° rotatable hose connectors make it easy to route the system even in tight spaces, and the 1.8 m hose length provides greater installation flexibility. Thanks to its compatibility with both freshwater and saltwater, the filter is suitable for various types of aquariums.
