Evolution Aqua Tempest Filter

The Tempest Filter is an innovative polishing system for ponds that will help to deliver crystal clear, healthy water. Designed to be used in conjunction with most filtration systems, the Tempest offers additional mechanical and biological filtration. The Evolution Aqua Tempest Filter can also be used on quarantine systems or as a standalone filter on smaller ponds.

The Evolution Aqua Tempest Pond Filter is easy to install and is simple and quick to clean, by way of a unique, patent pending air syphon design. 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. Not only that, K+Media is the result of extensive research and development, moulded with minerals for faster maturation times.

E A Tempest Filters can be installed on a variety of set-ups. On larger systems that require a higher flow rate, multiple Tempest Filters can be installed in a modular system.

How it works
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.

Easy to clean
With the pump turned off, slide valves closed, and waste valve open, air is drawn into the filter. As air and water mix inside the filter tube, the media starts to move chaotically, dislodging the trapped waste. Dirty water then exits the filter tube at the bottom via the waste line, leaving clean media.

K+Media – Advanced Filtration
K+Media is designed and manufactured by Evolution Aqua. This advanced media, with its innovative design and class leading surface area provides enhanced biological and mechanical filtration. As Evolution Aqua extrude the K+Media, minerals and enzymes are added to the raw material.

The result of this process, unique to Evolution Aqua, is a filtration media that not only outperforms most of its competitors due to its large protected surface area, but also answers the problem of how to speed up the time taken to mature your filter.

Dirty Harry Pre Filter

These Dirty Harry pre-filters provide you with an additional tool to keep your pond clean. The Dirty Harry pre-filter ensures that larger waste solids in the pond water, such as leaves, small branches and larger algae particles are collected before they are caught up in the pump or in the filter. By pre-filtering the water, you prevent larger particles from clogging up or overloading the filter.

They help save the service life of the pond pump is protected because large particles will not damage the impeller of the pump.

The housing of the Dirty Harry pre-filter is transparent, so it is easy to see when it needs cleaning.

The Dirty Harry pre-filter has a maximum pressure rating of 2 bar and comes complete with unions for 63 & 50mm solvent pipe, 1½” female threading and hose tails 25/32/40mm.
