Evolution Aqua Tempest Filter

The Evolution Aqua Tempest Filter is an innovative polishing system for ponds.It uses our latest filtration media, K+Media, to deliver crystal clear, healthy water.

Designed to be used in conjunction with any filtration system, the Tempest Filter offers additional mechanical and biological filtration. The Tempest can be installed on a variety of set-ups and can be used on quarantine systems or as a standalone filter on smaller ponds up to 5,000 litres / 1,100 Gallons.

Using Evolution Aqua’s K+Media as the filter media, particles down to one micron can be filtered. On a single pass, testing has proven our media capable of removing all particles down to 25 micron when used at the optimum flow rate. Not only that, K+Media is the result of extensive research and development and is molded with minerals for faster maturation times.

Water is pumped up through the filter. The K+Media moves to the top of the filter, becoming a mechanical barrier that traps debris as it flows through the system. Waste is trapped in the K+Media until the cleaning cycle dislodges it and it gets flushed away.

There are a number of ways the Tempest Filter can be installed on your pond system. Below are some typical installation ideas.

PLEASE NOTE: The slide valves fitted to the filter allow connection to 1½” pressure pipe. If installing the Filter using flexible hose you will need to fit a reducing sleeve and a 1½” solvent weld stepped hosetail inside each slide valve.

To allow the Tempest Filter to give the best performance, it is important that the flow rate is no more than the 5,000 litres per hour. Some of the installation examples show a by-pass that will enable you to increase the flow through the pond.
