Spiral Round Duct:

In the HVAC system, the biggest problem is how the air can be transported into the exhaust system effectively. The Spiral duct is known to be the most effective way of moving air because of the round profile shape, which helps to conserve energy in commercial and industrial buildings.

Spiral Round Ducts are designed & manufactured to comply with SMACNA & ASHRAE standards. The spiral round duct is produced by duct forming machine with strong spiral seams providing reinforcement that are made to meet ASTM A635.
