- Simple installation
The most compact POLO suction belt filter, SAFI-T series, cleans liquids fully automatically. The main field of application is the purification of highly viscous oils, such as those found in rolling processes and on presses. Due to its compact design, there is room for it on every machine and it is therefore very popular.
The dirty liquid flows into the dirt chamber of the filter through an inlet distributor that avoids turbulence.
The exhauster draws the liquid through the fleece into the inside of the perforated plate drum, thus creating a negative pressure. This negative pressure increases the flow rate, allows the filter cake to build up higher and, as air is drawn through this filter cake, produces a dry stab-proof discharge. The higher-building filter cake provides a high-quality filter layer that improves the degree of filtration.
The filter discharge pump directs the cleaned liquid into a clean tank. At a maximum level in the dirt chamber, a belt pre-stroke is triggered. At the same time, the used fleece is conveyed into the dirt container and a fresh fleece is drawn in. The filtering process does not have to be interrupted for this operation; no buffer tank is necessary!
