Spiral Ducting Solutions
Spiral ducting offers superior aerodynamic performance, modern aesthetic appearance, and faster installation compared to rectangular ductwork. Perfect HVAC Solutions delivers complete spiral ducting projects across India - especially for retail, restaurants, and architectural projects with exposed ceilings.
Why Choose Spiral Ducting
- 30-40 percent lower pressure drop than equivalent rectangular ducts
- Smaller cross-section for the same airflow capacity
- Lower air leakage from sealed spiral seams
- Faster installation with snap-lock fittings
- Aesthetic appearance suitable for exposed installations
- Available in painted finishes for architectural integration
Material and Finish Options
Our spiral ducting is available in standard galvanized iron, stainless steel (SS-304/SS-316 for corrosive environments), pre-painted GI in custom RAL colors for aesthetic exposed installations, and aluminum for special applications. Wall thickness ranges from 0.5mm to 1.6mm based on duct diameter and pressure class.
Comprehensive Fitting Range
We supply complete spiral ducting systems including straight lengths, 30/45/60/90 degree elbows, tees and crosses, reducers and increasers, end caps, volume control dampers, fire dampers, and grilles/registers/diffusers. All fittings feature compatible snap-lock or slip joint connections with sealed gaskets.
Applications
Spiral ducting is ideal for modern retail showrooms, restaurants and cafes, gymnasiums, exhibition halls, loft offices, fashion stores, supermarkets, and any project where exposed ductwork is part of the design aesthetic. Industrial applications include dust collection, fume extraction, and pneumatic conveying.
Installation Excellence
Spiral ducting installation is significantly faster than rectangular due to standard fitting interfaces and snap-lock connections. Our team handles design, layout, supply, and installation including proper supports, hangers, sealing, and integration with HVAC equipment.
Quality Assurance
All our spiral ducting meets SMACNA standards for round duct construction, EN 1506 European standards for circular ducts, and ASHRAE guidelines. Material certificates, leak testing, and installation documentation are provided with every project.
