Sand filter Bilbao 400 suitable for above-ground and in-ground pools up to 30 m3. The Bilbao filter features a split sand tank. The split tank allows for faster and easier sand replacement than filters with a top-mounted valve. In addition, when replacing the sand media, there is no risk of accidentally damaging the internal filter piping. Bilbao filter tanks are manufactured by plastic injection molding, which ensures high wall strength. The tanks are highly resistant to internal pressure as well as to chemical products used for pool maintenance. In terms of material quality, workmanship, and service life, Bilbao filters are among the best pool filters on the market. There are only a few sand filters that still work like new after twenty years without complaints. Easy installation and commissioning. Can be connected to pool PVC pipes as well as 50 mm flex hoses.
Filtration is part of the overall treatment of pool water. This means that the filtration unit itself, without proper chemical water treatment, cannot ensure the required water parameters. Likewise, chemical water treatment alone is not sufficient without filtration.

Filtration PrincipleWater is drawn by the pump from the bottom of the pool through the pool drain (1) and from the surface through the skimmers /collectors/ (2), via the valve (3) into the filter (5), where it is cleaned. It is then pushed back into the pool through the recirculation nozzles (6). The nozzles are located on the opposite side from where the bottom drain and skimmers are installed. The filter itself contains a sand media that traps insoluble impurities contained in the water. After a certain period of filtration, the sand becomes clogged and less permeable to water. It is therefore necessary to backwash the sand. Backwashing or rinsing is carried out by feeding water into the filter in the opposite direction to the filtration process. |
