Alphacool?s Eiszapfen series is forward-looking and distinguishes itself through its exceptional design and high flow rate. The Alphacool Eiszapfen deep black brass filter is ideal for water cooling systems with microstructure coolers. The filter prevents the microstructure coolers from becoming clogged, since these coolers are often difficult to clean manually due to their small size.  The filter is constructed so that there is no resistance through the mesh; the opposite, in fact: the flow rate of the filter is around 50% higher than a tube with an 8mm inner diameter and around 30% higher than a tube with a 10mm inner diameter. This makes the filter ideal for high-flow systems. Only once the filter is more than 30% to 50% clogged does a reduction in flow rate kick in.  This filter is available in three different colours: chrome, deep black and now also in plexi.
