Confined Space Ventilation
Alternatives
flexDUCT™ 150
Lightweight blower and ducting hose
Use for: Lower-duty ventilation within PVC temperature limits.
flexDUCT™ 150 is the lightweight PVC blower-and-ducting option. Its smooth bore and rigid external helix support routing and handling in lower-duty ventilation. Use it only when the air temperature and pressure or vacuum are within the published ratings.
flexDUCT™ 620
Hi-temp ducting and blower hose
Use for: Ventilation requiring EPDM construction or temperature capability.
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.
Notes: The primary selection is lightweight portable ventilation. PVC and EPDM alternatives address different construction and temperature requirements.
Distinction: flexDUCT™ U 520 is the lightweight portable-ventilation selection. The flexDUCT™ 150 alternative covers lower-duty PVC ventilation within its temperature limits. The flexDUCT™ 620 alternative addresses EPDM construction or temperature requirements.
Warning: Ventilation-hose selection does not establish safe confined-space entry. Verify air temperature, contaminants, pressure or vacuum and delivered airflow. Atmospheric testing, monitoring, ventilation-equipment placement and confined-space procedures must address the complete space and ventilation system.
