The F..-SPR-C rubber-insulated spiral ducts are specifically engineered for rapid deployment in ventilation and air-conditioning systems. Their primary benefit lies in the factory-fitted rubber foam insulation, which guarantees substantial time savings at the construction site compared to traditional, two-stage insulating processes. These ducts form the central spine of the FOAM System, ensuring high thermal performance and a clean, professional finish.
The ducts are available in a matrix of materials, lengths, and insulation thicknesses to suit various technical specifications and architectural requirements.
The integrity and fit of the F..-SPR-C ducts are based on the nominal inner diameter (Ød) and are produced according to PN-EN-1506:2001 tolerances, which contributes to the overall system tightness.
| Nominal Diameter Ød (mm) | Circumference (pi*d) (m) | Cross-sectional Area (pi*d^2/4) (m2) |
|---|---|---|
| 80 | 0.251 | 0.005 |
| 100 | 0.314 | 0.008 |
| 125 | 0.393 | 0.012 |
| 150 | 0.471 | 0.018 |
| 160 | 0.502 | 0.020 |
| 200 | 0.628 | 0.031 |
| 250 | 0.785 | 0.049 |
The insulation is a flexible foam with closed pores, made from synthetic rubber. This material offers reliable temperature insulation properties essential for energy-efficient HVAC operation.
