MAS “CDF” Continuous Disc Filtration System: The Answer to Better Melt Filtration
December 15, 2014
The MAS Continuous Disc Filtration, also known as the “CDF”, is a revolutionary adaptive melt filtration system which can be easily integrated into any current extrusion line that is in need of superior contaminant removal. The innovative CDF boasts many advantages over other continuous filters offered today.
Available in 4 sizes to accommodate a full range of capacities, the CDF removes up to 5% of soft contaminants such as Wood, Paper, Aluminum, Rubber and non-melting Polymers efficiently and continually.
It features an automatic melt pressure disc control system that automatically increases the disc rotation speed as well as the knife scraper pressure as needed to keep a stable melt pressure. This increased melt pressure stability has shown to increase current extruder capacity greatly.
A huge advantage of the CDF is that the discharge screw and the rotating disc work independently of each other. This allows the CDF and screw to be set at different RPMs, resulting in a massive advantage of minimal polymer loss and maximum contaminant discharge.
The CDF knife scrapers are set to a fixed point on the rotating disc allowing the contaminants which are present on the disc to be immediately removed as they are brought to the knife, not dragged across the filter screen by the knife as in other designs. This stationary knife design helps prevent the possibility of “cutting” or disintegration of the contaminants.
Additionally, the knife scraper is made of brass to prevent added wear to the screen during use. It also has an added advantage as it can be easily sharpened as needed, thereby prolonging its life and needing fewer replacements.
Please note: All values depend on the CDF model, material processed, filtration finesse, contaminant level, melt pressure, up and down stream equipment, etc.

An innovative manufacturer of plastic processing and plastic recycling equipment with a focus on high product quality and very low energy consumption, MAS’ product portfolio is comprised of 3 main components for the processing and recycling of plastic: Extruders, Continuous Disc Filtration and Dry Cleaning Systems.
The unique co-rotating conical twin screw MAS Extruder - their signature product - can be used in many different recycling, re-compounding, compounding and extrusion applications.
The patented MAS CDF (Continuous Disc Filter) can be used for many recycling applications to remove up to 5% of soft contaminates like paper, wood, aluminum, etc.
The MAS Dry Cleaning System can remove many types of dirt contamination (sand, dirt etc.) from thin wall rigids, film-and fiber flakes. This equipment is an ideal system to dry and clean plastic waste. It washes without water. Whether it is used as a standalone drying and cleaning system or as a supplemental technology for existing film washing lines it will do a great cleaning and drying job.
