The Alphacool Eiszapfen filter made of Deep Black brass is ideally suited for water cooling systems with microstructure coolers. The filter prevents clogging of a microstructure cooler, as such coolers are difficult to clean manually due to their small structures. The filter is designed to ensure that there is no resistance from the mesh. On the contrary, the flow rate of the mesh is approximately 50% larger than that of a hose with an 8 mm inner diameter and about 30% larger than that of a hose with a 10 mm inner diameter. Thus, this filter is ideal for high-flow systems. Only when the filter is more than 30% or 50% clogged does a reduction in flow occur.
