A radial blower is a blower composed of an impeller with radial blades, and the impeller's diameter is large for a given capacity because of the narrow impeller width relative to other blowers.

An airfoil blower is a blower composed of an impeller whose blade is tilted backward with respect to the rotational direction like a rear-bent blade blower, but the cross-section of the blade is an airfoil. Airfoil blowers are often used to transport clean air because of their low noise during operation. An axial blower is a blower that transports air in the same direction as the axial direction of the impeller, and is composed of a propeller-type impeller, and the impeller blade is an airfoil. In detail, the propeller blower is a tubeless blower and has the simplest structure among the axial flow blowers.

A propeller blower is often used to transport a large amount of air under low pressure, and is a good example for indoor ventilation and cooling towers. A tube axial blower is a blower with an impeller installed inside a tube. And the vane axial blower is a blower equipped with a guide blade to the tube axial blower, and is the same as the tube axial blower except for the vane. The vane of the vane axial blower prevents the swirling flow of the impeller wake, so it is more efficient than the tube axial blower and generates higher pressure.
