The Flowclear 3.028 L sand filter system from Bestway is efficient, environmentally friendly and reliably keeps the water in your above -ground pool clean. Since this pump uses quartz sand instead of filter cartridges, it is a particularly inexpensive filter method. While cartridges should be replaced every two weeks, quartz sand can be used for up to three years. The sand reliably catches dirt particles and impurities. A pre -filter with a removable strainer basket collects the coarse dirt beforehand and thus ensures a longer service life of the pump. Delivery includes a ChemConnect chemical dispenser, which distributes exactly the right amount of chlorine evenly, ensuring clean, healthy water throughout the pool. The product is delivered factory-assembled and is suitable for all 1,100-16,600 liter above-ground pools. The filter sand is not included - approximately 8.5kg of quartz sand No. 20, grain size 0.45-0.85mm are required. Alternatively, the Polysphere filter balls from Bestway can also be used for the filtering process.
