Here is a mini blue rotor siren I got recently. It is also the first one I have seen like it. It is unique in how it has straight rotor blades not backwards curved like on Carter Minimite sirens. I also cranked it right up near the end of the video & it blows alot of air when is is spinning at around 5 to 6,000 rpms. Does anyone know who made it & its model name?
I also grab one of my Minimite sirens in the video to show the size of this model. Near the end of the video I crank it right up & it is so loud & screams. Glad I had earmuffs this time because this little blue siren is potent & really packs a punch in sound.
