SUNSUN Internal filter pump with UV-C lamp 700 l/h CUP-809

The SUNSUN CUP-809 is a submersible filter pump with a built-in UV-C lamp, designed for aquariums up to about 750 litres. It combines mechanical filtration, water circulation, aeration and UV-C sterilisation in a single unit. The integrated 9 W UV lamp emits radiation at a wavelength of 253.7 nm, which helps reduce the growth of algae, bacteria and other microorganisms that degrade water quality. A flow rate of 700 l/h and a 10 W pump output maintain steady water movement throughout the tank.

The filter combines a sponge pre-filter with filter media that trap debris, while the aeration function supports oxygen levels in the water. The UV-C lamp has its own switch, so it can be operated independently of the pump to suit the needs of the aquarium.

Suction cups hold the unit securely inside the tank. The impeller, sponge, filter media and the quartz sleeve around the UV lamp are easy to reach, which simplifies regular cleaning. The maximum lift height is 0.7 m.
