| Product Description
Ventilation tunnel pipes feature flexible corrugated design with shield structure, suitable for low-clearance installations. Complete fitting systems ensure efficient airflow distribution in residential and commercial applications.
| Product Features
Shield Advantages
The unique tunnel structure delivers superior pressure resistance, minimizing ground pressure and making it an ideal choice for underground air duct installations.
High-quality and environmentally friendly
Made from high-density PE-HD using extrusion molding, this pipe eliminates the need for adhesive bonding (unlike traditional PVC ducts), resulting in enhanced safety, better eco-friendliness, and a longer service life.
Dual protection
Integrated anti-mold and anti-static components resist mold growth in humid conditions and dust buildup in dry environments, effectively preventing secondary contamination.
Insulation and noise reduction
Double-wall hollow structure reduces noise and provides insulation.
Flexible and sturdy
Corrugated construction is highly flexible and bendable, preventing air leakage along the pipe, while delivering a high compression resistance of up to 7kN/m².
Efficient air delivery
The smooth inner wall minimizes air resistance, and the quick plug-in connection prevents air leakage, enabling efficient airflow and easy maintenance and clean
| Product Specification
| Application
