ROUND SPIRAL DUCT

PRODUCT DATA:

ECCO Spiral Duct combines the economy of light gauge materials with a spirally formed lockseam construction that provides maximum strength and rigidity. Modern methods of production permits fabrication of long lengths of duct in 1" through 72" diameters. There is no limit to the length that can be manufactured. Limitations only applicable to transportation restrictions.

FEATURES:

• Airtight 4-ply lockseam;
• Low friction loss;
• Light weight;
• Long lengths.

• Aluminum;
• Cold rolled steel;
• Galvanized steel;
• Perforated steel;
• Polyvinyl chloride (PVC) coated steel;
• Pre-painted steel;
• Stainless steel;
• Wiped coat.

PROFILE SELECTION

Type P	Standard profile offers a smooth, high strength duct with low external seam friction loss.
Type P-IS	Internally seamed for a smooth outside wall construction. Specify at placement of order: Type P-IS.
Type 2-LC	Two light reinforcing corrugations for added strength. Light in weight and economical. Will not develop excessive pressure losses at low velocities. Same weight as Type P. Specify at placement of order: Type 2-LC.
Type C	Deep reinforcing corrugation for extra strength allows usage of lighter gauge materials. Will not develop excessive pressure losses at low velocities. Add 8% to weight of Type P. Specify at placement of order: Type C.
Type CC	Deep reinforcing corrugation for added strength, with a smooth inside construction for low friction loss. Add 10% to weight of Type P. Specify at placement of order: Type CC.
