Besides the ducts, there are other components that complete the duct system or referred to as ductwork system. Some of these components include vibration isolators, take-offs, volume control dampers, and many more. All of these have their own essential role in the system. Once one of these fail to do its job, your ductwork might require repair or any other services like maintenance to keep its performance and provide you the benefits it offers.Duct system starts at the air handlers most of the time. The blowers in such air handlers can make substantial vibration and the big area of the system could transmit the noise and the vibration to the people in the building.
To get rid of this, vibration isolators or the flexible sections are normally inserted into the duct quickly after and before the air handler. Such rubberized canvas-like of the section allows the air handlers to vibrate without transmitting vibration to the attached ducts. The same section may also lessen the noise that may occur when the positive air was introduced and the blowers engage with the ductwork.After the ductwork was created with a major duct branching into several branch ducts, take-offs is the used term in describing fittings that let the small portion of the flow in the major duct that will be diverted into each branch duct.
Take-offs can be fitted into a rectangular or round openings cut into the main duct’s wall. Take-offs commonly have small metal tabs that are bent to attach the take-off the primary duct. The round versions are called spin-in fittings. Several designs of the take-off use snap-in attachment strategy that is coupled with an adhesive foam gasket for a much better sealing. The outlet of the take-off then connect to the branch duct, which has oval, rectangular or round shape. Ductwork, especially in homes, must allow air to travel in vertically within thin walls.
Such vertical ducts are known as stacks, which can be formed with thin oval or rectangular sections. At the stack’s bottom, stack boots provide a transition from a typical huge rectangular or round duct to the thin duct mounted on the wall. Stack heads can also give a transition back to the common ducting while the register heads allow the transition to the mounted air registers in the walls.There are other ductwork components you should know. These include air terminals, turning vanes, terminal units, smoke or fire dampers, plenums, and volume control dampers. If these components are doing their part properly, expect that your ductwork will provide you peace of mind.
