Product Overview
SUPERFLO® HFL INK FILTERS AND SURGE SUPPRESSORS
Graymills Superflo® filters are specially designed for flexographic and gravure ink systems, providing effective filtration to eliminate quality problems from contaminants that can also damage costly anilox rolls. Convenient sizes for all printing applications. Filters are available standard (Models HFLT/HFST/HFNT) or as surge suppressors (Models DDPSFST/DDPSFNT).
Graymills Superflo® ink filters are designed to overcome the typical pressure drop and reduced ink flow due to clogging that occurs with ordinary filters. A permanent magnet (optional rare earth megaMAG available, see page 29) suspended over the intake port traps ferrous particles which find their way into the ink, and diffuses the flow outward into the filter screen flutes. Filtered material is trapped on the inside of the removable/reusable stainless steel filter cartridge. To clean, just remove the cartridge. All the contaminants come out with it. Graymills Superflo® filters are self-draining—no wasted ink or messy leftovers to deal with.
Rare Earth megaMAG™ Upgrade
For superior protection against anilox scoring/damage.
A rare earth magnet in a smooth stainless steel casing, with 10x the pulling power of a standard magnet, megaMAG™ is able to attract metal particles from within the filter body or ink tank. megaMAG™ provides a level of protection never before available. megaMAG™ can save the time required to pull a damaged anilox roll out of service and replace it, as well as the high cost of repair. Unlike other rare earth magnets, megaMAG’s domed end design with no crevices releases particles easily when cleaning.
megaMAG™ is available for use in Graymills Superflo® filters HFST or HFNT or on an adjustable bracket C-37327 or mini-megaMAG™ bracket C-38745 for placing inside a tank or pail. Also available for use in DDPSFST and DDPSFNT surge suppressor filters. Retrofits to all existing Superflo® filters and surge suppressor filters.
