Collector arm 3/4" 110 mm. filter Astralpool

Collector arm 3/4" and 110 mm long for pool filters Astralpool.

The collector arm or crepina are slotted pieces that are inside the filter.

They have 2 functions:

- When the filter is being filtered, it recovers the filtered water at the base of the filtering element, which will be returned to the pool.

- When the filter is being washed, the pressurised water that arrives through these crepinas allows the sponge of the filtering material to be lifted so that the retained waste can be evacuated to the outside.
