The NEW Tempest Filter is an innovative polishing system for ponds. The Tempest Filter 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 Filter 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.

The Tempest filter is easy to install and is simple and quick to clean, by way of a unique, patented air syphon design (UK Patent No. GB2550495B).

During the cleaning process, air is drawn into the filter as it empties which causes the water to agitate, effectively cleaning the K+Media.

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 moulded with minerals for faster maturation times.

Evolution Aqua filter media has been independently tested by Cranfield University and the IFTS (Institut de la Filtration et des Techniques Séparatives). IFTS International Filter Testing Services is the international reference for solid-liquid separation. Founded in 1981, IFTS is an independently regulated, ISO 17025 accredited, laboratory and research center focusing on liquid filtration and separation science. IFTS quality management system is certified to ISO 9001:2015.

Water is pumped up through the Tempest 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.

The Tempest Filter can be cleaned in matter of minutes, by simply turning the pump off, closing slide valves and opening the waste valve tap.
