Low consistency hydrocyclones

Low consistency cleaning involves removal of fine debris such as sand, ink, specks of bark, wax or bits of Styrofoam. The typical low density hydrocyclone operates at 1% consistency and is available in different configurations depending on the specific gravity of the unwanted particles.
