Spiral Duct Fitting, Flanged Collar

Steel plate fitting with hot-dip galvanization done by JIS G 3302. [Check the Safety Precautions in the Catalog]
[Features]
· High strength: The wax used in the molding of the spiral duct offers high reinforcing effects for use with high speed ducts, dust collection ducts and exhaust ducts.
· Low friction loss and leakage: The spiral duct has a high circularity and a smooth inner surface, making the resistance extremely small. It is known to have a strong lock seam that is machine-molded, and the leakage is only 1/1,000 compared to square ducts.
· Quick construction time: The connection work of the spiral duct is easy, the workability for hanging on the ceiling is good, and the construction can be completed at an extremely fast speed.
· Factory-produced material quality is stable and reliability of the construction can be expected.
· High economic efficiency: Spiral ducts are inexpensive because standard products are mass-produced in factories.
· The required airflow can be sent with a smaller surface area compared to a square duct, reducing the cost of heat insulation process.
