A propeller fan is primarily used to move air or gas in various applications, such as in HVAC systems, aircraft, and cooling systems. It generates airflow by rotating blades, which creates a pressure difference to draw in air and expel it in a specific direction. These fans are essential for ventilation, temperature control, and improving air circulation in both industrial and residential settings. Additionally, they are used in engines for thrust generation in aviation.
The rotor is like the engine to the propeller. A propeller is the fan like blades on the top that spin to make the helicopter fly.

Excrement - it is "when the excrement hits the rotating propeller blades."
The propeller on a turboprop airplane engine spins to move the aircraft through the air. It acts in a way similar to that of the blade in a fan.

A propeller is the object on the aircraft that rotates to produce thrust almost like a fan makes wind... it aims the wind behind it and pushes the aircraft forward
it looks like a small table top fan blade
A Carrier brand dehumidifier propeller fan costs $114.88. The fan blade set kit itself costs only $14.99 (from Emerson).
Axial fans are designed to move air parallel to the fan blade rotation axis, making them more suitable for applications requiring high airflow at lower pressures. Propeller fans have angled blades that push air in a specific direction, making them more efficient for moving air over long distances at higher pressures. Overall, axial fans are better for general cooling and ventilation, while propeller fans are ideal for air circulation and ventilation in specific directions.
Used as fasteners, a fan or ships propeller is a form of screw, etc.
A propeller works by converting the rotation of the engine into horizontal thrust similar to a fan. The blades push the air backwards creating acceleration, and create a difference in pressure between the forward and rear surface adding to the movement. The above is, of course true for a boat propeller. For an airplane propeller Bernoulli's pincipal is involved. Bernoulli's principle states that the greater the speed of a fluid, the less the lateral pressure. So the propeller uses the same deal as the wing.
Extract means "pull out", and a fan in this case is probably a propeller-like thingy used to move air. So an extractor fan is something that's used to draw air away from a certain area.
