Application guide
Hi-temp ducting and blower hose
flexDUCT™ 620 is the flexible EPDM blower-and-ducting option for compatible air and material movement. Its temperature capability and handling characteristics are distinct from those of PVC or polyurethane duct.
General ducting and blower hose
flexDUCT™ 625 adds an external metal wear strip to EPDM duct construction. The added protection addresses dragging and outside wear.
Medium-duty ducting and blower hose
flexDUCT™ 630 is the thicker-wall EPDM option for compatible medium-duty material movement. Its 4-, 6- and 8-inch size range is narrower than that of the general duct families.
Notes: This selection is for gravity-assisted auger downspout duty. It does not establish a pressure or vacuum rating for 630ED.
Distinction: flexDUCT™ 620 favors flexibility and temperature capability; flexDUCT™ 625 adds protection against exterior dragging; flexDUCT™ 630 favors internal grain-abrasion resistance in its 4-, 6- and 8-inch sizes. Confirm grain temperature, routing and mechanical support. This gravity-downspout selection does not establish a pressure or vacuum rating for flexDUCT™ 630.
