HEISSNER Pressure Filters

Pond filter systems for biotopes, garden ponds & compact fish ponds

Pressure filters represent a space-saving and versatile solution for water treatment in garden ponds. Thanks to their sealed construction, they can be discreetly positioned and will operate flawlessly even when installed below the water level. Pressure filters are particularly ideal for small to medium-sized fish and ornamental ponds, as they effectively combine mechanical filtration with biological filter processes.

The HEISSNER range comprises high-efficiency pressure filter systems that are engineered to harmonise with technical precision with the appropriate pond pumps, consistently ensuring crystal-clear water.

The operating principle of a pressure filter
A pressure filter is a hermetically sealed system in which pond water is forced through various filter media under constant pressure via a pump. A major advantage of this design is that the purified water can be easily directed to higher-elevation watercourses or source stones after the filtration process.

Ideal applications

  • Compact to medium-sized garden and ornamental ponds
  • Pond installations with moderate fish stocking levels
  • Gardens featuring streams or architectural elevation changes
  • Properties with limited space for filtration equipment

What are the advantages of a pressure filter?

  • Space-saving and compact design
  • Discreet installation (can often be partially buried or recessed)
  • Enables the operation of elevated water features
  • User-friendly maintenance and handling across many models

Optimal runtime
To guarantee biological equilibrium, the pressure filter should run continuously, 24 hours a day during the season. In the winter months, operation can be reduced or suspended, depending on the frost depth and the specific conditions of your pond.

Maintenance and cleaning intervals
Depending on the nutrient load and fish population, cleaning should be scheduled approximately every 2 to 6 weeks. Shorter intervals may be necessary during the warmer months, particularly during periods of intense algae growth or high feeding levels.
