AquaForte Ultrasieve III Gravity Fed Sieve Filter

The most compact, gravity fed, sieve filter with the highest pump capacity!

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

How it works: Pond water will flow over the top of the self-adjusting weir (A). This weir 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.

The UltraSieve III comes with a pump connection of a 2" male threaded adaptor. The pump connection comes with a long suction pipe which draws the water from under the float to prevent air suction.
