Astral pool Berlin filter with multiport valve 21000 l/h Ø 750 mm

Astral Pool Berlin filter is a type of sand filter for swimming pool filtration systems. The multiport valve is an important component of this filter, as it allows for easy switching between different functions of the filter, such as filtration, backwashing, rinsing, and draining.

Here are some key features and functions of the Astral Pool Berlin filter with multiport valve:

• Filter Tank: The filter tank is made of high-quality, corrosion-resistant material and is designed to withstand high pressure.
• Sand Media: The filter uses sand as the filter media, which effectively removes dirt and debris from the water.
• Multiport Valve: The multiport valve is located on the top of the filter tank and controls the different functions of the filter.
• It has six positions: filter, backwash, rinse, waste, closed, and recirculate.
• Filtration: When the multiport valve is set to "filter," water is pumped through the filter tank and the sand media, which traps dirt and debris.
• Backwashing: Over time, the sand media can become clogged with dirt and debris, reducing its effectiveness. To clean the filter, the multiport valve is set to "backwash," which reverses the flow of water through the filter and flushes out the trapped dirt and debris.
• Rinsing: After backwashing, the multiport valve can be set to "rinse" to remove any remaining debris from the filter.
• Waste: If the pool water is particularly dirty or has high levels of debris, the multiport valve can be set to "waste" to bypass the filter and send the water directly out of the system.
• Closed: The "closed" position is used when the filter is not in use, such as during winterization.
• Recirculate: The "recirculate" position bypasses the filter and sends water directly back into the pool, useful for temporary situations when the filter may be undergoing maintenance or repair.

Technical details:

• Connections: 2” outlet
• Multiport valve: Included
• Maximum pressure (kg/cm2): 2.5

Overall, the AstralPool Berlin filter with multiport valve is a reliable and efficient way to keep pool water clean and clear.

Proper maintenance and regular cleaning of the filter and sand media will ensure optimal performance and extend the lifespan of the system.
