That is actually a different 02 motor. If you look at the bottom the more powerful 02 fan has a star shaped blade and the less powerful one that sounds like yours has a spiral shaped blade. It's like the more modern SJD-B1 is quieter but looks the same at a glance but the SJD-B2 is more louder and has a different sound
That's a great Halloween inflatable. We had that one for a lot of years

My 2002 Friendly Ghost and My Ghost On Pumpkin have the same fan sound
