Disc filters fall into the category of “depth filtration” filters because they add an additional dimension to the cleaning process. A filter element contains a stack of compressed discs with an overlapping series of grooves that force the debris to move through numerous trap points. This process increases the likelihood of capturing debris. Because of the increase in filtration surface area, the frequency of cleaning drops and cleaning is easier.
The discs are color coded by mesh size and are selected according to water filtration requirements. The spine assembly has a spring compression unit and an internal piston which are used to alternately compress and release the discs during filtering and backflushing cycles.
Filtration Mode
During the filtration process, the discs are tightly compressed together allowing clean water to pass through the discs and trap debris.
Backflush Mode
As debris in a filter increases, the backflush process is initiated. During backflush, the discs separate and jets of clean water spray and spin the discs removing the trapped debris which is then flushed out.
Improved Filter Spine
With a longer spine assembly and larger discs, the Apollo Filter has a 20% larger filtration area than a comparable Galaxy filter. The Apollo features a redesigned piston which allows backflushing at lower pressure, 30 psi – 25% lower than a Galaxy.
Easier Access to the Discs
With an easy-to-release clamp around each filter, there are no tools required to remove the filter cover and access the discs. This makes maintenance and troubleshooting quick and simple.
