In this filter the filter paper is held between a pair of sealing
discs & a permeable support belt. Dirty fluid is dropped in
the trough formed with filter paper at the bottom. The fluid passes
through the filter paper leaving the dirt on it. The layer of dirt
gathered on the filter paper achieves finer filtration. The filter
is mounted directly on top of the tank, letting clean fluid in the
tank. As the filter paper chokes, the fluid level
above the filter paper rises.
This activates a level switch, starting
a drive coupled to the rollers, supporting the permeable support
belt. This ejects part of the dirty filter paper & dirt to bin,
pulling in clean filter paper from the roll.
Suitable for fine filtration of coolants used in grinding, honing,
gun drilling & component washing applications.
