The NBPF-15000 pressure filter is a weather-resistant filtration system for ponds. It effectively purifies water using three filter sponges, bio balls, and a built-in 24 W UV lamp. The large surface area of the sponges and bio balls provides ideal conditions for the growth of nitrifying bacterial cultures. The UV lamp eliminates pathogens and algae that cause green water. The filter can be installed underground to preserve the natural look of the pond edge (IP44 standard). The pressure filter ensures excellent water quality and an optimal environment for both fish and plants in ponds up to 20 000 L.

The filter is sold without a pump. We recommend pairing it with an energy-efficient, high-performance pond pump from the ECO EP series, such as the EP 8000. These pumps are suitable for use in fountains, filters, cascades, and garden ponds.
How Does the NBPF-15000 Filter Water?
- Stage 1 – Mechanical: water is pumped into the filter, creating the necessary pressure to begin mechanical filtration. Three foam sponges capture organic debris of various sizes, promoting the growth of beneficial bacteria that break down harmful pollutants.
- Stage 2 – Biological: water flows through bio balls at the bottom of the filter. These provide a large surface area for beneficial bacteria that naturally convert toxic ammonia and nitrites into safe nitrates, supporting a healthy pond environment.
- Stage 3 – UV Sterilization: water passes through the UV lamp, which destroys microscopic algae spores and ensures crystal-clear water. The UV lamp operates at an optimal temperature in a sealed chamber.
Maintenance
UV-C lamp replacement: UV-C lamp has a lifespan of 7 000 to 10 000 hours. We recommend replacing it annually and cleaning the quartz sleeve for optimal performance.
Foam sponge maintenance: if the sponges become clogged, remove and rinse them in chlorine-free water (e.g., pond water). Sponges may shrink—restore their original size using steam from boiling water.
