These fans are located in a gas station. There are three of them, controlled by a remote control.
These fans do not reverse with a remote, they have a reverse switch on top of the motor housing, which are too high to reach obviously. One of the employees said that one of them is on updraft to help air circulation.
RPM estimation on the one on updraft: 46/94/126
RPM estimation on the middle one: 52/94/139

They have a little wobble, and they blow okay amount of air without much noise. All three fans are shown on all three speeds.
