A blower apparatus is provided especially suitable for an air curtain, screen or barrier. The apparatus includes a blower in the form of a plurality of blades arranged to describe a cylinder. A guide encircles the blower, but is open-ended thereupon and extends axially beyond the blower to generate an air stream, the width of which is greater than that of the blower. A deflector or interceptor plate is arranged, which is coextensive with that portion of the guide, which extends beyond the blower and which is coextensive with a portion of the blower in a range of about 45 DEG -90 DEG thereof. The deflector or interceptor plate prevents air from circulating in an axial direction back into the blower and therefore improves the effectiveness of generation of the air stream, which flows tangentially out of the blower arrangement.
