The invention provides an electric pressure fan and an electric dust collector having the same, with which the situation that air flow from a shield to a wheel hub becomes uneven is prevented; the matching between a static blade disposed at the downstream of a rotating blade and the airflow is realized; the internal loss of the rotating blade and the peeling loss of the internal static blade are reduced. As for the blade, near an inlet, the shield side of the blade inclines towards a rotation direction and then faces the outer edge of the blade. The inclination of the shield side approaches awheel hub side, turning into an approximately two-dimensional shape facing the outer edge of the blade, and the shield side of the blade inclines towards a direction opposite to the rotation direction. When the blade approaches to the outer edge, the inclination towards the direction opposite to the rotation direction is reduced and an approximately two-dimensional shape is formed near the outer edge. Observed from an axial direction, two approximately two-dimensional shapes are provided from the inner edge of the blade to the outer edge of the blade, and inclining shapes with changed rotation direction are provided before and after the approximately two-dimensional shapes.
