Description
SUNSUN HW404B 9W/UV External Filter
The SUNSUN HW404B is a high-performance external filter designed for freshwater and saltwater aquariums with a capacity of up to 600 liters. The unit offers a water flow rate of 2,000 l/h and features a spacious 19-liter housing with a 4-stage filtration system that effectively removes contaminants and helps maintain stable conditions in the tank. An additional advantage is the integrated 9-watt UV-C lamp, which helps eliminate algae, bacteria, and microorganisms responsible for deteriorating water quality.
Built-in UV-C Lamp and Convenient Operation
The integrated UV-C sterilizer irradiates the flowing water, limiting the growth of algae and harmful microorganisms. The filter is also equipped with a manual pump to facilitate initial startup and a multifunctional valve with a quick-connect fitting, which allows you to disconnect the hoses without having to drain the system. The 360° swivel hose connections make it easy to install the filter under or next to the aquarium, and the rubber feet effectively dampen vibrations during operation.
High Performance and Robust Construction
The housing, made of durable ABS and PVC plastics, ensures high resistance to daily use. The filter features a ceramic impeller shaft, which ensures stable operation. The maximum water lift is 2.5 m, and the included hoses—1.8 m long with a diameter of 20/25 mm—facilitate installation even with larger tanks. The design meets the IPX4 water resistance standard and can operate at temperatures ranging from 4°C to 35°C.
