Combi Filter 20/25 Red Label
The filter consists mainly of a tank in which is housed a rotating drum: this drum is coated with a 70 micron (0.07 mm) filter membrane on its periphery.
The dirty water from the basin is directed into the drum and, to leave the filter, the water must pass through the filter membrane.
The water from the basin, which is freed from the particles, exits the filter and is directed towards the biological part of the filter.
As the dirty water passes through the drum, the particles are deposited by obstructing the small holes in the membrane, which gradually clogs.
The passage of the water is braked, which causes a difference in level between the downstream and the upstream of the sieve.
At this time, the detection system starts a drum cleaning cycle. At this moment, the drum turns very slowly and the nozzles arranged on the upper part (external side of the drum) project jets of water onto the filter membrane: under the pressure of the water, the smallest dirt is expelled from the Filter membrane.
These dirt are recovered in a gutter and directed to the sewer. The upstream / downstream water level is restored to the next cycle.
This cleaning is minimalist: it only intervenes when necessary.
This model also includes a biological filter: water first passes from the drum part (mechanical filtration) to the biological part from which it will then be evacuated to the basin.
They are numerous and the first one comes to mind: good filtration is based on the principle of removing as quickly as possible a maximum of particles and extracting them from the water of the basin so that they can no longer harm.
A "normal" filter can only retain what it can ... and the waste it retains degrades in water. With a drum, this is not the case, biological filtration is less stressed, which in many cases allows to reduce its volume.
Second big advantage: provided you have a reasonable UV power, the water is clear all year round. No problems!
Third advantage: finished cleaning the grid prefilter or brushes, a drum filter is self-cleaning. Let's be honest, this filter nevertheless requires a minimum of attention because it is a machine, and therefore some minor interventions are to be expected, but absolutely nothing binding.
Finally, each brand, each model has its peculiarities: it is up to you to determine the exact type of filter you need.
Pumping or gravity, stainless steel or polypropylene, with or without biological filter? These are the first criteria of choice but the most important is its size. Remember that a filter is never too large: the rinsing frequency will be comfortable (3 to 4 rinses per hour in summer for a dozen per day in winter).
On the other hand, a filter too small will consume more water because it will have to rinse more often. We are at your disposal to guide you in your choice.
Concerning the biological part of the filter: the manufacturers propose for the majority of the biological filters fluidized (the media are brewed by air). By being reasonable, the amount of media is enough in most cases. If your pool has an abnormally high density of residents, you have the option of providing an additional biological filter (and different, which is preferable).
