– Easy to drain. No lost sand, thanks to a manual bleeder valve for water in the sand purge plug.
– Functionality. The advanced technology developed for the Cantabric filters offers extraordinary reliability in operation with low maintenance, allowing the filters to run safely with optimal pool filtering for many years. The equipment also includes the AstralPool 6+1 multiport valve with filter, backwash, rinse, recirculate, waste, and closed positions.
– Innovative design. Apart from functionality, AstralPool is concerned with creating a new image for its Cantabric filters, an approach that has led to a product with an attractive, unique design based on the use of a ivory tone and an innovative shape, while also focusing on adaptability to the needs of location.
– Extensive range. Cantabric filters provide an ideal solution for a wide variety of pool sizes, as they meet the filtering needs of pools between 30 and 240 m3 with flow rates of 6,000 l/h to 30,000 l/h at a filtering rate of 50 m3/h/m2.
