Sunsun External Filter HW-704A

SUNSUN HW-704A External Filter
The SUNSUN HW-704A is a high-performance external filter designed for aquariums with a capacity of up to 1,000 liters. With a flow rate of 2,000 l/h and a power consumption of 45 W, it effectively maintains high water quality in both freshwater and saltwater tanks. The design is optimized for quiet operation, and rubber vibration-dampening elements help reduce noise generated during operation. Thanks to its compact dimensions of 300 x 300 x 490 mm, the filter can be conveniently placed under or next to the aquarium.


Four-stage filtration for clean and healthy water
The HW-704A model uses a 4-stage filtration system that effectively removes contaminants and helps maintain stable water parameters. Mechanical filtration traps larger impurities and suspended particles, while biological media provide a large surface area for the growth of beneficial bacteria responsible for breaking down harmful substances. The design of the filter baskets also allows for customizing the filter cartridges to the specific needs of the aquarium. Filter media are not included in the set.


Convenient operation and easy maintenance
The filter is equipped with a practical pre-filter that traps larger debris before it reaches the main filter media. This solution extends the service life of the remaining cartridges and simplifies maintenance of the entire system. The built-in manual pump allows you to quickly prime the filter before starting it, and the multifunctional valve with a quick-connect fitting enables you to disconnect the hoses without having to drain them. Additionally, the 360° swivel hose connections make it easy to install and position the unit even in tight spaces.


Efficient Operation in Various Conditions
The SUNSUN HW-704A is equipped with a pump featuring a ceramic shaft, which is distinguished by its durability and resistance to long-term operation. The maximum lift height is 2.5 m, ensuring efficient water circulation even in larger aquarium setups. The unit operates at temperatures ranging from 4°C to 35°C and has an IPX4 protection rating. Its suitability for both freshwater and saltwater aquariums makes this filter ideal for a wide variety of tank setups.
