PVC Flexible Ventilation Ducting Tube

A heavy-duty, highly flexible ventilation duct engineered for positive blowing and negative pressure exhaust applications in marine, industrial, and confined spaces. Constructed from strong biaxial polyester with double-skin coating, it features an integrated spring steel helix to prevent collapsing, making it the ideal accessory for portable axial fans and blowers.

Key Features & Construction

• Heavy-Duty Materials: Made of high-tensile biaxial polyester with double-skin coating for enhanced tear resistance, waterproofing, and flame-retardant performance.

• Anti-Collapse Structure: Encased spring steel wire helix with rubber-wrapped black reinforcement strips prevents duct collapse under strong negative suction.

• Temperature & Chemical Resistance: Operates reliably in extreme temperatures ranging from -20°C to +80°C (-4°F to +176°F); resists water and oleic acid.

• Easy Attachment: Open ends are fortified with steel collars, an adjustable clamp, and a rope cinch for quick, secure attachment to fans and duct connectors.

• Portable & Compact: Lightweight design that rolls up compactly for hassle-free storage, handling, and transport.
