Commercial ductwork runs through all ceilings in each room, ensuring consistent airflow. While the structure and design of rooms and buildings change, the ductwork remains steadfast and recognisable. We have put together a list of the most common commercial ductwork parts.

Outlets

Grills, diffusers and registers divide up the ductwork and the airflow. A diffuser brings in air to an otherwise unconditioned airspace, refreshing the room or cutting down on noise. Register boxes offer choice; they can be opened and closed when more or less air flow is needed.

Dampers

These regulate the air flow throughout the ductwork. They can be used to change and adjust air flow, and they can also detect fire and smoke. This means that they can shut off a section of the ductwork, ensuring the smoke does not spread.

Fittings

These balance the air flow, equalise pressure and shape the ductwork when it needs to reduce in size. A reducer is used to switch from one size of spiral duct to another. For example, www.dustspares.co.uk/ductwork-parts/galvanised-steel-spiral-duct.html has many sizes from which to choose. These balance the air flow, equalise pressure and form the duct structure when it needs to reduce in size. In addition to regulating flow, vent caps are fittings that seal off and protect an open end of duct work.

Air handlers

These attach onto a ductwork system. For use indoors or outdoors, these air handlers can be used to heat or cool air, or they can be used to dampen noise or filter the air in the ducts.

Plenum

This is the hub of the ductwork system and the core distributer of air to the duct system. There are two types, much like a two-way street. One, the supply, directs air from the heating or air conditioning system to be distributed around the system. The second, the return, directs the air back to the central distributer.

Vents

These let the warm or cool air out of the ductwork and into the rooms. Flat and placed at the opening of a duct, some are manual so people can direct the warm and cool air to their liking.
