Blown-film extrusion plants may be able to reduce airborne contaminants by as much as 80% with a new patented Saturn Evacuation System (SES) from Future Design Inc. and extend cleanings from every six weeks to quarterly or longer. Future Design, which is part of Gloucester Engineering Co., specializes in air ring technology for the flexible packaging industry.
The SES is comprised of a small air ring that fits any air ring or die that is constructed of aluminum and fits between the die and the primary cooling ring. Connected to the vacuum side of the blower, the system creates a positive vacuum that draws as much as 80% of the contamination from the low-pressure zone at the die exit. The polluted air is filtered and the discharged particulates directed to a suitable location....
