The leaf is the heart of the filter. We can offer Omega Keyhole Channel filter leaves as well as Rigid filter leaves. All filter leaves can be manufactured out of various materials, such as 316L SS or special alloys.
The Key Hole Channel filter leave consists of several layers of wire mesh. The inner layer is a coarse mesh for the discharge of the filtrate and support of the outer layers. On top of the support layer there's a course drainage layer with on top of it a final filter mesh is mounted. The whole is fitted in an omega key hole channel. This design allows a full flow with minimum restrictions. The leaves are available in bolted or riveted construction. As an alternative Twin Filter offers an extra Rigid and durable filter leaf. The life time of the leaf can be up to 20 years. The're constructed of fully welded perforated sheets with support channels designed for a low pressure loss. The perforated sheets are covered with replaceable mesh, bolted to the frame. The filter leaves can be easily re-meshed at site.
Twin Filter also offers filter leaves with special media, for instance laser perforated holes or etched openings. These filter leaves offer the advantage of a good chemical resistance and an excellent cake release. Synthetic leaves are available in Polypropylene, PVDF or other material on request. These filter leaves are covered by synthetic filter material. The filter cake is discharged as a wet slurry.
