According to the company, twin actuator DCF filters process quick-drying, highly abrasive, and sticky fluids, as well as thicker, viscous liquids. Available in DCF-800 and DCF-1600 filter units, the twin actuator filters operate by using a cleaning disk to eliminate contaminants in less than a second from the filter's interior surface. Applications include chemicals, resins, pharmaceuticals, adhesives, and coatings, since the DCF mechanically cleaned filters can dispose of solids 15 microns and larger.
