Spiral Duct Fitting Rubber Packing

Sealing for flange connection. [Check the Safety Precautions in the Catalog]

[Features]
· The wax used in the molding of the spiral duct offers sufficient reinforcing effects for use with high speed ducts, dust collection ducts and exhaust ducts.
· The spiral duct has a high circularity and a smooth inner surface, so the resistance is extremely small. It is known that it has a strong lock seam that is machine-molded, and that its leakage is only 1/1,000 compared to square ducts, etc.
· The connection work of the spiral duct is easy, the workability for hanging on the ceiling, etc., is good, and the construction period becomes extremely fast.
· Factory-produced material quality is stable and reliability of the construction can be expected.
· 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.
