Flexible Ventilation Pipe with Stainless Steel D-Rings & Flame Retardant PVC - NUOENWEI
Our flexible plastic air duct redefines versatility for ventilation and exhaust applications. Engineered with advanced polymer technology and robust structural components, this duct system delivers unmatched performance across industries:
Unlimited Extension Design
- Flared ends with integrated PP rope & optional buckle/zipper connectors enable rapid, leak-free coupling of multiple ducts.
- Interlocking high-carbon steel rings ensure airtight continuity during expansion/contraction cycles.
Corrosion-Proof Suspension
- Stainless steel D-ring hangers with heavy-duty straps provide rust-resistant support for permanent installations.
Extreme Environment Resilience
- B1 fire-rated PVC withstands temperatures from -30°C to +80°C, resistant to acids, alkalis, and tearing.
- Abrasion-resistant polymer coating protects spring steel骨架 from mechanical wear.
Dynamic Flexibility
- 360° bend radius with memory-retention spring steel allows precise routing around obstacles without airflow loss.
