|The fan itself is the same size. I think this is the adjustable "attic fan" series. You mounted to the floor in front of a window or vent in the attic. This has a 1" threaded pipe so you just bought the one to the size you need to raise the fan to the proper height. I have another early one like this that is a countertop version that has a adjustable collar like yours.
