The Ultrasieve III is the most compact, gravity fed, sieve filter with the highest pump capacity on the koi market!

For years the Ultrasieve III has been the leading and most reliable pre-filter for professional koi ponds. The Ultrasieve III is supplied with an extra large waste outlet, including a slide valve 90/110mm!

A few years after the introduction of the successful UltraSieve II it has been superceded by the Ultrasieve III. Most important features of the Ultrasieve III are the improved flow regulation and the new waste outlet which have fine tuned the overall performance. The total sizeof the Ultrasieve III is now more compact so it occupies less space.

How the Ultrasieve III works: Pond water will flow over the top of the auto-adjustable dam. This dam is connected to the float so its height is automatically adjusted. This system will ensure that the exact amount of water that is pumped out the filter will enter the filter on the inlet. Underneath the screen the unit now has stabilizers to prevent expansion when the unit, accidentally, totally fills with water. The UltraSieve III comes with a pump connection of a 2" male threaded adaptor. The waste outlet on the Ultrasieve III is fitted with a 90/110mm slide valve
