WFHFF High-Flow-Pleated cartridges with diameter of 152mm and lengths from 20“ to 60“ are suitable for the very high flow rates. The internal filter structure is horizontal pleated and for all lengths continuously made from one piece of filter media with 97-99% retention efficiency. This creates a lot of space for high dirt hold capacity and long life time.
High-Flow-Pleated Cartridges are available in the two adapter-configurations type P and type M, see picture below. The flow rate of type P is from inside to out-side and of type M from outside to inside. For the installation of the High-Flow-Pleated Cartridges type P and type M special made filter housings are needed
