AstralPool 1" collector arms or nozzles for sand pool filters.
The function of the nozzles is to capture the water from the bottom of the filter once it has been filtered. During filter washing, they are responsible for lifting the filter load and evacuating the residues retained in the treatment plant.
Every so often (8-10 years) it is recommended to completely empty the filter load of your pool filter and check the existing nozzles in the filter.
