Durable equipment — Good-quality central vacuum systems can last indefinitely, perhaps requiring replacement of the motor brushes once per decade of use. [10] Besides using heavy-duty components, central vacuums avoid the damage caused by accidental dropping or collisions of portable equipment with fixed objects.
Process duct work conveys large volumes of hot, dusty air from processing equipment to mills, baghouses to other process equipment. Process duct work may be round or rectangular. Although round duct work costs more to fabricate than rectangular duct work, it requires fewer stiffeners and is favored in many applications over rectangular ductwork ...

Round duct is made using a continuous spiral forming machine which can make round duct in nearly any diameter when using the right forming die and to any length to suit, but the most common stock sizes range evenly from 4" to 24" (10-60 cm) with 6"-12" (15-30 cm) being most commonly used. Stock pipe is usually sold in 10' (300 cm) joints.
