Your benefit with MAS with a CDF melt filter


The larger filtration surface of up to 200 % results in a lower melt pressure and therefore a lower mechanical strain on the material, better filtration results and reduced material losses. Filtration surface compared: CDF 500-D from MAS: 3280 cm², Competitor I 350: 1570 cm², Competitor II 2/350: 1470 cm².


The larger filtration surface allows lower melt pressure before the filter system, which results in a reduced mechanical strain and therefore a longer lifetime of the filter screen. Example from real life: A MAS customer filters 3024 tons per filter screen set with a filtration fineness of 250 microns, washed post-consumer polypropylene, another customer filters 2850 tons per filter screen set.


The larger filtration surface and lower melt pressure is a key contributor to a higher quality of the final product due to filtration performance. This will result in higher customer satisfaction through improved quality as well as increased prices for better quality pellets.


Filter systems from MAS are designed in order to control and optimize the waste discharge of the filter.  This can be achieved by the individual control of the filter screen speed, discharge screw speed, and the scraper system pressure.


The variable scraper system pressure not only results in less material loss but also a better filtration result, due to variable pneumatic pressure system the lifetime of the filter screens is improved tremendously. The feedbacks of our customers reflect the fact that filter screens from MAS have up 25 % greater lifetime compared to other manufacturers.
