Ultrasieve 3 Lid

The Ultrasieve 3 is the most compact, gravity fed, sieve filter with the highest pump capacity on the koi market!

For years the Ultrasieve 3 has been the leading and most reliable pre-filter for professional koi ponds. The Ultrasieve 3 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A few years after the introduction of the successful UltraSieve II it has been superceded by the Ultrasieve 3. 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 it 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 3 comes with a pump connection of a 2″ male threaded adaptor. The waste outlet is fitted with a 90/110mm slide valve
