Ultrasieve 3 Standard (MAX FLOW 4000GPH)

UltraSieve filters are the most reliable pre-filters on the market. This is partly due to the simple design, with just one moving part. The pre-filter is not self-cleaning, but it is very easy to maintain. Open the slide valve and the debris can be washed away. The UltraSieve pre-filters have a stainless steel filter element that never needs to be replaced. Thanks to the triangular stainless steel rods at a 7° angle, the water falls directly through the sieve, but the debris remains. A major advantage of this principle is that the debris is truly removed from the water circulation. This is highly beneficial to the water quality, because waste products are no longer polluting the water.

How it works
The pond water flows over the top of moving weir. This moving weir is connected to a float, so the height of this weir is controlled automatically. This level feedback mechanism ensures that the exact amount of water that is pumped enters again. The sieve consists of hundreds of triangular rods spaced 0.2 or 0.3 mm (200 or 300 microns) apart. The rods are slightly angled so the coarser particles remain on the sieve and the ‘sieved’ water falls through. The sieved water is led further to the main filter.
