The two most common types of exhaust fans are impeller fans and blower fans. The first, impeller fans, moves the air with blades like a propeller air plan. Blower fans move the air with a hamster wheel like blade system. The latter of the two is considered to move air around better. Kitchen exhaust fans must be accompanied with a duct system and an exhaust hood in order to function properly. Kitchen exhaust fans are unlike other home exhaust fans in that their design has both the fan and fan motor inside the hood. Kitchen exhaust fans are also usually louder than other fans.
