Nordfab ducting systems are designed for straightforward installation, but challenges can arise. Understanding common issues and their solutions helps ensure your system performs optimally from day one.
This guide addresses the most frequent installation problems and provides practical solutions.
Clamp Connection Issues
Proper clamp installation is critical for air-tight connections. If you're experiencing air leaks at joints, the cause is often improper clamp positioning or insufficient tightening.
- Ensure clamps are positioned over the bead on each duct section
- Tighten clamps evenly around the circumference
- Check that gaskets are properly seated
- Use appropriate clamp sizes for your duct diameter
Airflow Problems
Inadequate airflow can result from design issues or installation errors. Verify that duct sizing matches your system requirements and that transitions between sizes are properly oriented.
Check for obstructions, kinks, or excessive bends that may restrict airflow.
Support and Alignment
Ductwork must be properly supported to maintain alignment and prevent stress on connections. Space hangers according to manufacturer recommendations and ensure vertical runs are adequately braced.
Misaligned sections create stress points that can lead to leaks and premature wear.
