The Tempest 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.How The Tempest Filter WorksWater 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.How To Clean The Tempest FilterThe Tempest Filter can be cleaned in matter of minutes, by simply turning the pump off, closing slide valves and opening the waste valve tap.Specification Max Pond Size Inlet Outlet Drain Size Max Flow Rate 5,000 Litres1,100 UK Gallons1,320 US Gallons 1½” UK / USA50mm EU 1½” UK / USA50mm EU 1” UK / USA32mm EU 7,500 Litres/hr1,650 UK Gallons/hr1,980 US Gallons/hr Optimum Flow Rate Volume of Water in Filter Dimensions Amount of K+Media Supplied 5,000 Litres/hr1,100 UK Gallons/hr1,320 US Gallons/hr 27 Litres5.9 UK Gallons7.1 US Gallons 1055mm x 250mm x 205mm 7 Litres 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.Installing the Tempest FilterThere 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 Tempest Filter allow connection to 1½” pressure pipe. If installing the Tempest Filter using flexible hose you will need to fit a reducing sleeve (EA Code: M35-050) and a 1½” solvent weld stepped hosetail (EA Code: HOSETAIL15) 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 aby-pass that will enable you to increase the flow through the pond.TYPICAL INSTALLATION WITH A GRAVITY-FED FILTERYou can install a Tempest Filter after a primary filter on a gravity-fed set-up, such as the Nexus+, and after a UV Clarifier, such as an evoUV. The slide valves on the Tempest Filter connect to 1½” pressure pipe.The installation example shown below has a by-pass that will enable you to increase the flow through your pond while maintaining the optimum flow through the Tempest Filter. Installing ball valves on the pipe work will help you regulate the flow. The return from the Tempest can go back to the centre of your Nexus+ or back into the pond.TYPICAL INSTALLATION ON A PRESSURISED SYSTEMYou can install a Tempest Filter on a pressurised system with a K1 Micro Bead, Nexus+, EazyPod. The slide valves on the Tempest Filter connect to 1½” pressure pipe.The installation example shown below has a by-pass that will enable you to increase the flow through your pond while maintaining the optimum flow through the Tempest Filter. Installing ball valves on the pipe work will help you regulate the flow. The return from the Tempest and the K1 Micro Bead go back to the pond.TYPICAL STANDALONE TEMPEST FILTER INSTALLATIONYou can install a Tempest Filter on a quarantine system, or a standalone pond up to 5,000 litres, at the side of a pond or above the pond.The slide valves on the Tempest Filter enable connection to 1½” pressure pipe. If installing the Tempest Filter using flexible hose you will need to fit a reducing sleeve (EA Code: M35-050) and a 1½” solvent stepped hosetail (EA Code: HOSETAIL15) inside each slide valve.TYPICAL SKIMMER LINE INSTALLATIONYou can install a Tempest Filter on a skimmer line.The slide valves on the Tempest Filter enable connection to 1½” pressure pipe. If installing the Tempest Filter using flexible hose you will need to fit a reducing sleeve(EA Code: M35-050) and a 1½” solvent stepped hosetail (EA Code: HOSETAIL15) inside each slide valve.MODULAR TEMPEST FILTER INSTALLATIONOn larger systems that require a higher flow rate, multiple Tempest Filters can be installed in a modular system. The slide valves on the Tempest Filter enable connection to 1½” pressure pipe. If installing the Tempest Filter using flexible hose you will need to fit a reducing sleeve (EA Code: M35-050) and a 1½” solvent stepped hosetail (EA Code: HOSETAIL15) inside each slide valve.It is important that each Tempest Filter can be isolated using the slide valves so that cleaning can be carried out independently. Although on the installation diagram below we show two filters into one return line, independent return lines will allow you to observe the flow rate through both Tempest Filters and balance accordingly.
