Applications of the proper materials and components in mechanical systems which carry and distribute the conditioned or free air to places, are important as much as choosing them. For a high system performance, materials of high quality should be used correctly on application field. At this point, the parameters below should be taken into consideration about choosing and mounting flexible air ducts:

• To determine the diameter of the flexible air duct
• To determine the mounting length of the flexible air duct
• The numbers and the degrees of the elbows and the bends (S pieces) needed
• The construction system of the flexible air duct
• The connection of the flexible air duct with the distributing/gathering equipment
• To attach the flexible air ducts to each other
