A fluid conditioning assembly includes a fluid conditioning device defining a passage and having a first end and a second end. A control element is supported within the passage. At least the first end includes an integral radially outwardly directed flange. The integral radially outwardly directed flange is configured to be operatively and releasably coupled to a first radially outwardly directed flange of a first duct section. A technician may release the fluid conditioning device from the first duct section to remove the fluid conditioning device from the ventilation duct system for accessing the control element of the fluid conditioning device.

A damper access assembly includes an adapter and a removable damper access duct section for use in a ventilation duct system to access a damper. The adapter includes a radially outwardly directed flange. Each of the ends of the damper access duct section includes a radially outwardly directed flange. The flange of the adapter is configured to be operatively and releasably coupled to one of the flanges of the damper access duct section. The other second flange at the other end of the damper access duct section is configured to be operatively and releasably coupled to the ductwork. A technician may release the damper access duct section from the adapter and from the ductwork and remove the damper access duct section to access the damper. The damper access assembly may include one or more clamps that cooperate with the flanges of the adapter and the removable access duct section.

A sealing gasket for a ventilation duct system includes an annular gasket body and a pair of annular sealing flanges extending radially outwardly from the gasket body. The sealing gasket has, in axial cross-section, a generally flat top wall and a curved or, alternatively, a radiused bottom wall. One of the sealing flanges is positioned adjacent one circumferential edge of the sealing gasket and the other sealing flange is positioned axially spaced from or offset from the opposite circumferential edge of the sealing gasket. The sealing gasket is provided to form a generally air-tight seal between overlapping ends of first and second components of a ventilation duct system.

A system is configured for forming a flange at an end of a tube. The system includes a collar configured to receive the tube. A first roller engages the collar and a second roller is configured to cooperate with the first roller to rotate the collar and the tube. A rotatable cam is disposed about the second roller and includes a cam surface configured to bend the end of the tube to thereby form the flange. The collar may be configured to restrict axial movement of the tube relative to the collar. Additionally or alternatively, the collar may be configured to restrict rotational movement of the tube relative to the collar.

A juncture assembly is provided between first and second ends of respective first and second tubes. The assembly includes a first flange that is located at the first end and a second flange that is located at the second end, with the second flange being in confronting relationship with the first flange. The first and second flanges define a gap between them. A gasket member contacts the first and second flanges and is configured to prevent flow of fluids through the gap. A clamp member of the assembly secures the gasket member to the first and second flanges with the clamp member including a channel for receiving the first and second flanges and first and second restriction elements that extend into the channel for positioning the first and second flanges within the channel.
