Why Your Spiral Duct Machine Choice Matters
When you invest in a spiral tubeformer, you're committing to a production capacity that defines your shop's output for the next decade. Pick the wrong size, and you'll either turn away large-diameter orders or pay for capacity you'll never use.
At Preda Machine, we've helped over 500 HVAC fabricators across 100+ countries find the right spiral duct machine. This guide breaks down our three most popular models — the PD1600, PD1200 Band Spiral, and PD2000 Heavy-Duty.
Quick Answer
Most shops choose the PD1600 — it handles 80–1600mm diameter, 0.4–1.2mm thickness, covering 90% of commercial HVAC needs. Choose PD1200 if budget is tight and you only need up to 1200mm. Choose PD2000 if you regularly produce 1500–2000mm industrial duct.
PD1600 vs PD1200 vs PD2000: Head-to-Head
| Specification | PD1600 | PD1200 Band | PD2000 Heavy |
|---|---|---|---|
| Diameter Range | 80–1600mm | 100–1200mm | 200–2000mm |
| Material Thickness | 0.4–1.2mm | 0.4–1.0mm | 0.5–2.0mm |
| Forming Speed | 0–25 m/min | 0–18 m/min | 0–20 m/min |
| Motor Power | 7.5 kW | 5.5 kW | 11 kW |
| Best For | General commercial HVAC | Small shops, budget | Industrial, large-diameter |
PD1600: The Best-Selling Workhorse
The PD1600 spiral tubeformer is the backbone of many HVAC shops. It strikes the perfect balance between capacity and affordability, handling 80–1600mm diameter — covering virtually every commercial HVAC application.
- Versatile diameter range: 80–1600mm handles residential, commercial, and light industrial
- Fast production: Up to 25 m/min — a 3m duct in under 10 seconds
- PLC control: Mitsubishi PLC with touchscreen HMI — new operators productive within a day
- Plasma cut upgrade: Automatic cut-to-length eliminates manual cutting and waste
- Proven reliability: 2,000+ units deployed, many running 2+ shifts for 10+ years
PD1200 Band Spiral: Budget-Friendly
The PD1200 Band Spiral uses a band-type forming system, making it more affordable and lighter while still delivering quality spiral duct up to 1200mm.
- 30–40% lower cost than PD1600 — ideal for new businesses
- Compact footprint — fits shops with limited space
- Easy maintenance — band-type design has fewer moving parts
Before You Buy
PD1200 maxes at 1200mm/1.0mm. If you might need 1200–1600mm in 2–3 years, buy PD1600 now — upgrading later costs more.
PD2000 Heavy-Duty: For Large Diameter
The PD2000 Heavy-Duty handles 1500–2000mm diameter and up to 2.0mm thickness — built for industrial ventilation, mining, and tunnel projects.
How to Choose
- Max diameter? ≤1200→PD1200, ≤1600→PD1600, ≤2000→PD2000
- Material thickness? Standard 0.5–0.8mm works on all. Thick 1.0–2.0mm needs PD1600/PD2000
- Daily volume? High-volume → PD1600's 25m/min. Low-volume → PD1200 saves money
- 5-year growth? Expect larger projects? Buy next size up now
