Drum filter Inazuma Katan GT20 BioKompakt

The Inazuma GT20 drum filter from the Katan range filters your pond thoroughly, reliably and fully automatically. This model is suitable for operating a pool of up to 20 m³.

The performance of large drum filters is now also available for the garden pond. The installation, the complicated connection, it's over. From now on, small garden ponds can be fitted with automatic filtration which continuously operates with the characteristics of large drum filters.

The GT20 BioKompakt model combines mechanical water cleaning with biological water filtration. During the cleaning of the water by the drum, particles larger than 50 microns are separated and sent to the sewer !.

Biological filtration with filter media can break down pollutants in the water and maintain the health of your fish. An optional UVC lamp also provides effective control of algae.

The massive stainless steel construction V4A (1.4571) makes the Inazuma GT20 a machine for many years.

Model GT20 can only be used for pump mode operation (see diagrams below)
The GT30, GT50 and GT80 models operate in pumping or gravity mode but do not include a biological chamber.

The removable cover allows easy access to the filter, the V4A stainless steel body ensures long lasting quality.

All filters in the Katan series come with a simple and ingenious controller featuring a Clever V8 microprocessor: you plug in the plug and you're done.

Configuration or adjustment is not necessary, the rinses are performed automatically.
The filter is also equipped with a manual rinse.

The guaranteed spare parts supply directly from the manufacturer ensures long-lasting peace of mind with a robust, low-maintenance filter. And with the quality "Made in Germany".
The 2 year warranty is included, the Clever controller and of course the high pressure pump.

A pre-mounted bracket is also included but not the UVC lamp (s).

What are the differences with the Septem series ?

The Katan series does not have a WebCSA connected controller: its regulation is simplified and nevertheless allows automatic operation.

This Katan series does not have gas struts on the cover: but the cover is light and removable.

The waste discharge chute can be rinsed manually: the Septem series too, but automatically.

Either ... but the rest, the frame, the pump, the motor, the drum are of equivalent quality!

Automatic 50 micron filtration!

For those who don't know how this filter works.

The filter mainly consists of a tank in which is housed a rotating drum: this drum is coated with a 50 micron (0.05 mm) filter membrane on its periphery.

The dirty water from the basin is directed into the interior of the drum and, to leave this filter, the water must pass through the filter membrane.

The water in the basin, which is freed of particles, leaves the filter and is directed to the biological part of the filter.

As the dirty water passes through the drum, the particles settle, blocking the small holes in the membrane which gradually clogs.

The passage of water is slowed down, causing a difference in level between downstream and upstream of the sieve.

At this time, the detection system starts a drum cleaning cycle. From this moment, the drum turns very slowly and the nozzles placed on the upper part (outer side of the drum) project water jets on the filter membrane: under the pressure of the water, the smallest dirt is expelled from the filter membrane.

This dirt is collected in a gutter and directed to the sewer. The upstream / downstream water level is restored until the next cycle.

This cleaning is minimalist in nature: it only occurs when necessary.

This model also includes a biological filter: the water first passes from the drum part (mechanical filtration) to the biological part from where it will then be evacuated to the basin.
