Abstract: A blower comprising a blower housing, a blower wheel, and a motor. The blower wheel is within the blower housing and has a plurality of blades. The motor is operatively connected to the blower wheel to rotate the blower wheel about an axis of rotation. The blower housing comprises a wall perpendicular to the axis of rotation. The wall has a static tap hole having a leading edge and a trailing edge. The static tap hole is positioned near an axial side of the blower wheel such that as the blower wheel rotates, any of the blades of the blower wheel passes the leading edge of the static tap hole before passing the trailing edge of the static tap hole. The wall comprises a protrusion protruding axially from the wall and toward the blower wheel. The protrusion is located adjacent the trailing edge of the static tap hole.
