Sunsun Pond BIO Pressure Filter CPF-3500 11W UV (CPF-3500 11W UV)

SUNSUN CPF-3500 11W UV Pressure Filter for Ponds
The SUNSUN CPF-3500 is a compact pressure filter designed for small ponds, decorative ponds, and fish tanks where maintaining good water quality and limiting algae growth are important. The model is equipped with an ll W UV-C lamp, which supports the purification process and helps maintain better water clarity. The filter is compatible with pumps with a flow rate of up to 7,000 l/h, has a filter chamber capacity of 20 liters, and features connectors that allow for the connection of hoses of various diameters. The unit is designed for fish ponds with a capacity of up to 4 m³ and decorative ponds without fish with a capacity of up to 8 m³, providing effective mechanical, biological, and UV-C filtration.


Effective water purification in a single unit
The CPF-3500 filter uses a combination of mechanical and biological filtration, helping to remove contaminants that accumulate during the pond’s daily operation. The filter cartridges trap fine suspended particles, sediments, and organic debris that could negatively affect water quality. At the same time, beneficial bacteria develop inside the filter, supporting natural biological purification processes. This solution helps maintain more stable conditions for fish, plants, and other organisms inhabiting the pond.


The 11W UV-C lamp helps combat green water
The built-in 11 W UV-C sterilizer helps limit the growth of algae responsible for green and cloudy water. Ultraviolet radiation causes the algae to clump together into larger particles, which can then be captured by the filter media. This improves the clarity of the pond and makes maintenance easier. The combination of the UV-C lamp with mechanical and biological filtration provides comprehensive support for maintaining good water quality.


Compact design and convenient operation
The filter’s pressurized design allows for discreet installation along the edge of a pond or partial concealment below ground level. As a result, the unit does not detract from the garden’s aesthetics and remains nearly invisible during daily use. The filter is equipped with a system that facilitates the cleaning of filter cartridges and a clogging indicator that helps monitor the unit’s condition. The purified water can be directed to small waterfalls, streams, or other decorative features located above the filter’s level.
