Other than the ducts, there are several components that actually make the whole duct system or known as ductwork. Some of the components are volume control dampers, take-offs, and vibration isolators, and much more. All of these play an important 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 systems often starts at an air handler. 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 avoid this, the flexible sections or vibration isolators are inserted normally in the duct immediately after and before air handlers. Such rubberized canvas-like of the section allows the air handlers to vibrate without transmitting vibration to the attached ducts. The same section can also minimize the noise that can occur when the blowers engage and positive air was presented to 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 also be fitted in to round or rectangular openings that can be cut into the primary wall of the main duct. Normally, take-offs have small metal tabs that are bent to attach the take-offs the main duct. The round versions are called spin-in fittings. Some designs of take-off utilize snap-in attachment method, which is coupled with adhesive foam gasket for enhanced sealing. The take-off’s outlet then connect to the rectangular, round or oval branch duct. Ductwork, especially in homes, must allow air to travel in vertically within thin walls.
These vertical ducts are called stacks that can be formed within thin rectangular or oval sections. At the bottom of the stacks, the stack boots give a transition from the regular huge round or rectangular duct to the thin duct that’s 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 parts of the ductwork such as smoke or fire dampers, volume control dampers, plenum, air terminals, turning vanes, and terminal units. If these components are doing their part properly, expect that your ductwork will provide you peace of mind.
