- Suitable for the large flow volumes
- Compressed dirt cake, dry, landfillable
- Low maintenance
- High filter fineness can be achieved
In endless belt design, the filters of the SAFI-C series can be subjected to very large flow rates. As a stand-alone filter, up to max. 8000 litres per minute can be achieved. This high-performance system is the essential core element of central systems. Due to a modular design, the high-performance system can be expanded to achieve even higher flow rates.
The medium is fed to the filter by the inlet distributor, flows through the filter medium and reaches the vacuum chamber cleaned. The filter discharge pump sucks the medium out of the vacuum chamber and conveys it into the clean tank.
The exhauster creates a negative pressure in the vacuum chamber. This negative pressure supports the flow rate considerably and results in a better utilisation of the filter medium due to a higher dirt cake build-up. The built-up filter cake provides an additional, high-quality filter layer and thus improves the degree of filtration.
The pressure gradient between the clean and dirty side, caused by the exhauster, is dimensioned in such a way that the finest particles are washed up but not pulled through. The dirt particles are deposited on the filter aid and reduce the flow more and more.
The level rises on the dirt side of the filter. At a preset level, there is a belt stroke (approx. 50 mm long). The filter cake emerging from the liquid is exposed to the suction effect of the exhauster and is well dried out, additionally supported by the exhaust air of the exhauster.
The dirt is brushed off and dropped into the dirt box. The endless belt is subsequently rinsed clean with purified medium.
The filter process is not interrupted during continued cycling, an additional buffer tank is not necessary!
The built-up filter cake is a valuable filter aid and significantly improves the degree of purity. Due to the short stroke steps, this “precoat medium” is almost completely preserved and the degree of purity remains unchanged.
