Marimex PROSTAR 2 PLUS, made in the Czech Republic, is suitable for pools up to 6 m3 which makes it an ideal accessory especially for smaller pools. ProStar Plus 2 sand filtration was inspired by nature - here, rainwater also turns into crystal clear spring water thanks to filtration in the permeable layers of the rock. In sand filtration, the water passes through silica sand, where even fine impurities are captured and only clean, filtered water returns to the pool. That is why it is important to rinse the filter sand frequently so that impurities do not settle in the sand. It is recommended to rinse the filtration at least once a week. The ProStar Plus 2 sand filtration system consists of a filter vessel that can hold 10 kg of filter sand. The container is made of high quality polypropylene (PP). It is seamless, resistant to corrosion and commonly available chemicals used in swimming pools. In addition to an attractive modern design, it has pleasing compact dimensions, a practical pump with a screen for coarse dirt built-in directly in the body of the container. The six-way valve offers a lightened position for winter season.
