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.
Notes: This selection is for compatible construction-site ventilation where dragging and exterior wear are important.
Distinction: flexDUCT™ 620 suits compatible ventilation where exterior dragging is limited. flexDUCT™ 625 adds an external wear strip for repeated jobsite movement and outside wear.
Limitation: Evaluate fan output, diameter, hose length and bends together. Long runs, crushed hose and tight bends reduce delivered airflow. Verify air temperature, pressure or vacuum and contaminants; hose selection alone does not establish adequate ventilation or safe confined-space entry.
