Collector arm 1˝ 100 mm / 0.3 mm – extension part (4 pcs)

The extension collector arms for the Cantabric filter vessel are used to adapt the length of the central collector to the height of the specific filter vessel. The set contains 4 arms with a 1-inch thread, a length of 100 mm, and a lateral slot of 0.3 mm, which is key to the correct capture of the sand filter medium and the passage of cleaned water. Too large a slot would cause sand to leak into the pool, too small a one would clog the arms and reduce the flow. The original parts guarantee precise dimensions and material resistance to pressure and chemicals. Suitable for standard renovation or extension of the collector when replacing the sand in the Cantabric filter.
