SUNSUN CUP-809 filter pump

The SUNSUN CUP-809 is a multifunctional filter pump designed for aquariums with a capacity of up to 750 liters, combining mechanical filtration, water circulation, aeration, and UV-C sterilization in a single unit. The built-in 9 W UV lamp emits radiation with a wavelength of 253.7 nm, helping to reduce the growth of algae, bacteria, and other microorganisms responsible for deteriorating water quality. A flow rate of 700 l/h and a pump power of 10 W allow for effective maintenance of proper water flow and clarity in the aquarium.

Comprehensive aquarium care

The device uses a combination of mechanical filtration and UV-C radiation, ensuring that the water is not only purified of contaminants but also sterilized. The built-in filter sponge and filter media help trap contaminants, while the aeration function helps maintain adequate oxygen levels in the tank. An additional convenience is the ability to independently turn the UV-C lamp on and off using a separate switch, allowing you to adjust the unit’s operation to the aquarium’s current needs.

Convenient operation and easy maintenance

The CUP-807 model is equipped with suction cups for stable mounting inside the aquarium. The design provides easy access to the impeller, filter sponge, filter media, and the quartz tube covering the UV lamp, which significantly facilitates regular cleaning and maintenance. A maximum lift height of 0.7 m ensures effective operation, and the total power of 20 W provides adequate performance for daily use.
