As a rule, two-part star filters, where the support tube can be reused, are beneficial for our planet as they conserve resources. However, sometimes one-part star filters are also desired and are better suited for some applications. We have therefore expanded our portfolio of filter elements to include one-part star filters. These have a stainless steel end plate at the top and bottom and an integrated stainless steel support tube. The filter medium is firmly cast on both sides. Polyurethane or silicone is used depending on the requirements. The upper end plate has our standard thread and can be easily installed in existing systems. Standard lengths are 20, 40, 60 and 100 cm, but intermediate lengths can also be realized.
