📐 Dust Collection System Design

Designing Your Ducting Layout

Proper duct design balances airflow (CFM), static pressure loss, and branch balancing. Key factors include: total air volume required per machine, duct velocity targets (3,500–4,500 FPM for wood dust), and selecting the correct branch angles to minimize turbulence.

❓ Frequently Asked Questions

What is a "rolled lip" fitting?

Rolled lip (RL) fittings have a formed bead at each end that accepts a standard clamp. This allows tool-free, leak-resistant connections that can be easily reconfigured.

What gauge steel should I choose?

For most dust collection systems under 10" diameter, 22–24 gauge is sufficient. Larger diameters (13"+) typically use 20ga for added rigidity. High-velocity or abrasive material applications may warrant 18ga.

Are these parts compatible with Nordfab?

Yes — our rolled lip components use the same bead geometry and clamp profile as the Nordfab Quick-Fit® system, making them directly compatible.

Do you ship same-day or next-day?

In-stock parts placed by noon (Central) typically ship same day. Contact us for expedited availability on specific parts.

Can you make custom lengths or diameters?

Yes. Our custom fabrication service handles non-standard sizes, lengths, and configurations. Use the Services page or call us to discuss your project.

What O-ring material should I choose?

Buna-N (standard) suits most woodworking and metalworking applications up to ~225°F. For higher temperatures or food contact, choose our red silicone/FDA O-ring option.
