Eiszapfen Acrylic/Acetal Inline Filter G1/4 IG 29142 The Alphacool Eiszapfen acrylic acetal inline filter protects your water circuit from unwanted particles. The hole thickness of the filter screen is 0.5 mm. This catches all particles that could potentially damage the pump. The filter consists of four parts: two caps, each with a G1/4" internal thread, the sieve insert and a crystal-clear acrylic cylinder, which is used for visual inspection. When dirt particles accumulate in the filter screen, it is easy to see that the filter needs to be cleaned thanks to the crystal-clear acrylic cylinder.
