The collector arms are a key distribution element inside every pressure filter tank. Their 0.3 mm wide slots let the filtered water through but retain even the finest grains of filter sand or glass over 0.3 mm in diameter.
This set contains two arms 225 mm long with a 1″ thread, designed for Cantabric filter tanks. The material resists chlorinated water and the pressure of backwashing, during which the water flows through the arm in the opposite direction.
A cracked or clogged arm causes uneven washing of the filter and the passage of filter media into the pool – immediate replacement prevents bigger problems. The set of two pieces covers the typical replacement during a service inspection.
