A device for drying a web, such as paper web. Air distribution boxes 4 are arranged on both sides of the plane 2 of a path of guidance for the web. Each one of the distribution boxes includes a line of first opening means 6 extending transversally to the direction of guidance and arranged to direct the air essentially perpendicularly towards said plane, and a line of opening means 8 essentially parallel to the line of first opening means and arranged to direct the fluid essentially along said plane. Guide means 22 direct the air issued from opening means 8 away from the line of first opening means 6 towards and along an adjoining surface portion 10 of the box on a higher level than the line of first opening means 6. Each line of the first opening means in the box on either side of said plane is located in front of said surface portion 10 of the confronting box located on other side of the plane.
