Collector arm 1" - 225 MM.

Collector arm 1" for lengthening collectors of Astralpool swimming pool filters. This collector has a thread on one side to be able to link to the collector head and thread on the other to join with another collector arm by means of the link handle.

The function of crepes is as follows:

• When it's filtering, it retrieves at the base of the filter element, the filtered water that's going to return to the pool.

• When the filter is washed, the pressurized water that comes through these crepes, allows the sponge of the filter material to rise to be able to evacuate the retained waste to the outside.

Every few years (8-10 years) it is advisable to completely empty the filter load of your pool filter and check for crevices in the filter.

The caliber of the groove is 0.3 mm.
