Surface Preparation Dust Collection
Better
flexDUCT™ U 535
Middleweight blower and ducting hose
flexDUCT™ U 535 is the middleweight polyurethane duct. It retains multidirectional routing and visual flow inspection while adding wall weight and, at relevant sizes, suction capability over the lighter 520U.
Best
flexDUCT™ U 545
Heavy-duty blower and ducting hose
flexDUCT™ U 545 is the heavy-duty polyurethane duct for more demanding internal wear. Its pressure and vacuum limits vary substantially with diameter; a heavier wall does not make every size a full-vacuum hose.
Notes: Use the polyurethane duct family for compatible surface-preparation dust collection. Contaminants and collector vacuum must be identified.
Match the selected diameter to the collector’s actual vacuum and routing. Dust control and any required bonding and grounding apply to the complete collection system.
Distinction: flexDUCT™ U 520 favors low weight and operator mobility. flexDUCT™ U 535 suits general commercial collection equipment. flexDUCT™ U 545 addresses greater internal-abrasion demands. All selections remain subject to the selected diameter’s vacuum rating; internal-wear rankings do not establish resistance to every external dragging condition.
