Made of polyethylene with UV-treatment (suitable for outdoor use) and manufactured using a rotomoulding process, which makes walls thicker so they can they resist more pressure, thus ensuring the service life of the filter.

Filters have six-way multiport valves with selector handle for the following positions: filter, waste, backwash, rinse, recirculate and closed.

Sports filters

CULZONI S.A. manufactures filtration equipments that can be used in standard or special dimension water sports swimming pools, suitable for a “traditional recirculation system” as well as for a “reverse recirculation system”.

These filters are made of stainless steel and receive an internal treatment to prevent corrosion effects.
One of our most outstanding works is that done during the 1995 Pan-American Games in Mar del Plata, in which we were the Official Providers of the Olympic Swimming Pool filtration system.


Pan-American Games

The filtration plant of the Olympic swimming pools for the 1995 Pan-American Games in Mar del Plata is a clear example of the use of these equipments.

The Reverse Recirculation System used in these swimming pools was based on the technology chosen in Barcelona’s Olympic swimming pools, in which water enters from the lower part of the swimming pool and returns to the surge tanks by surface and perimeter overflow.

Filters are equipped with a single Multiport valve with seven ports, which allows you to perform all the functions by operating only one command.

They have 4-inch valves which

are made in Germany.
