FEATURES:

Helical's finest standard Spiral Oval Duct gives you good reason to switch from the old-fashioned rectangular duct to the new-age spiral round rigid duct.

WHY? What advantages does a spiral system have over a rectangular one? The answer is simple. The perimeter of the round ducting system is less by 20% or more of a similar cross-section in rectangular ducting. Consequently, the area of ducting and insulation required is lower by the same percentage.

ADVANTAGES:

• Seamless by design
• Prevents air from leaking out of the ducts
• Outstanding quality contributes in
  improving the energy efficiency in your home
• Decreases noise pollution
• Simple and less costly to install and operate
• Lightweight
• Requires less space

APPLICATIONS:

• Air-conditioning connection lines
