Product Catalog

Semi-rigid polymer tubing for horizontal mine and tunnel ventilation.

Features:

• HardLine tubing can be formed to round or oval.
• Oval is designed to maximize drift/tunnel headroom by 25%.
• Resilient and durable polymer material (RigiFLEX-FR) is purpose-built for mine and tunnel ventilation.
• Tubing offers industry-leading high-efficiency airflow and low-leakage coupling.
• Available for positive and negative pressure applications.
• Hi-visibility safety green color.
• Quick-to-install coupling system.
• Fire Resistant for mine safety and to meet local codes.
• For shipping and storage HardLine Ducting is compressed down to help reduce cost.

Specifications:

Diameter Range: 14” – 72” (356mm – 1830mm)
Standard Length: 8’ and 10’ (2.45m, 3.05m). Longer lengths available.

Material:

• RigiFLEX-FR Polymer Grades:
• SD (Standard Duty) for light-weight and positive pressure applications.
• MD (Medium Duty) for positive and moderate negative pressure applications
• XD (Extreme Duty) for accessories, negative pressure and high-impact applications.
• RigiFLEX-FR offers a consistent and smooth surface to maximize airflow efficiency.
• Polymer does not fracture, de-laminate or lose bond.
• Safe to handle as there are no fibers that fracture, cut or contaminate the air.
