In-line fans are characterized by which configuration?

Inline fans are a duct-mounted type where the blower sits in the duct and the motor is kept outside the airstream. The described configurations—motor outside with belts and pulleys inside a grease-tight housing, motor outside with no protective housing, or motor located inside the airstream—do not reflect how inline fans are used in this application. Since this system does not employ inline fans, none of those arrangements apply. The correct takeaway is that inline fans are not used in this application.
