The Alphacool Eiszapfen Acryl acrylic inline filter protects your water loop from unwanted particles. The hole thickness of the filter screen is 0.5 mm. So all particles that could possibly damage the pump are caught. The filter consists of four parts: Two caps, each with a G1/4″ female thread, the filter insert and a crystal clear acrylic cylinder, which serves for visual inspection. If dirt particles accumulate in the filter, it is easy to determine that the filter needs cleaning, thanks to the crystal clear acrylic cylinder.
