Flexible duct hoses, often referred to as black PVC ducting, are used for low-pressure air and dust transfer applications. They feature a PVC inner tube, a single-ply reinforcement layer (typically fabric or plastic), and a corrugated PVC outer cover for increased flexibility. These hoses are commonly used for:

HVAC applications (low pressure): Low-pressure air ducting in ventilation systems.
Dust collection systems (low pressure): Transferring dust and debris in workshop or industrial settings.
Fume extraction (low pressure): Removing fumes or light smoke in some low-pressure applications (check suitability for specific fumes).
Temporary ventilation: Providing temporary air ventilation for events or construction sites.

Benefits

1. Lightweight and flexible: Easy to install and route in various configurations.
   
2. Corrugated design: Enhances flexibility for tight bends and maneuvering.
   
3. Durable PVC construction: Offers good resistance to abrasion and weather (depending on specific hose formulation).
   
4. Leak-proof performance: Ensures efficient low-pressure air or dust transfer.
