Industrial Cone / Witches Hat Filters

For those applications needing more than the drop-in, off-the-shelf wiches hat filter, Norman Filter Company manufactures industrial cone/witches hat filters for systems using 4” to 16” pipe. NFC's cone filters utilize a proprietary support structure, featuring all TIG welded construction for superior durability. NFC cone filters utilize wire mesh or random metal fiber (RMF) filtration media for superior durability and cleanability. Our cone filters feature a customer-selected internal/external support cage which is ideal for forward, reverse, and back-pulsing flow applications

NFC Cone Filters are manufactured with a matching flange which alleviates the need for pressure vessels or custom housings. Flanged Norman cone are attached to ANSI/ASME 16.5 flanges for easy alignment and installation in new and existing pipelines.

Pleated media in the Norman cone filter increases dirt-holding over t-type filters and standard mesh-wrap drop-in withces hat filters. Norman Cone Filters ensure less frequent changes, over longer periods reducing system downtime. The pipleline-integrated footprint of the cone filter eliminates the need for the bowl clearance of t-type filters, therefore adding filtration capability for hard to reach locations.
