Astral pool berlin filter without multiport valve 21000 l/h Ø 750 mm

The Astral Pool Berlin filter is a high-performance filter designed to remove debris and impurities from pool water.

Unlike many other pool filters, the Berlin filter does not use a multiport valve to control the flow of water through the filter media.

Instead, the Berlin filter uses a unique design that incorporates a large, cylindrical tank filled with filter media such as sand or glass. Water enters the tank through a central pipe, which distributes the water evenly across the filter media. The water then flows through the media, which traps debris and impurities, before exiting the tank through a separate pipe.

Technical details:

• Connections: 2 ½” outlet
• Maximum pressure (kg/cm2): 2.5

To clean the filter, the system is shut down and the tank is drained. The filter media is then backwashed using a separate pump or blower, which reverses the flow of water through the filter media and dislodges any trapped debris. The dirty water is then flushed out of the system and the filter is ready to be used again.

Overall, the Astral Pool Berlin filter offers efficient and effective filtration without the need for a multiport valve. However, it is important to follow the manufacturer's instructions carefully when cleaning and maintaining the filter to ensure optimal performance and longevity.
