The AprilAire ARN43C flexible couplings are used as a means of coupling 3” and 4” PVC. They are also used for disconnecting the PVC pipe for servicing the unit as well as vibration isolation. As the fan is typically outside of the building thermal boundary and is venting to the outside, installation of insulation around the fan is not required.
