Abstract
A method and apparatus for adjusting the amount of clearance between the tips of the blades of a large axial flow fan and the inner surfaces of the fan cylinder wall. A plurality of foam spacer panels are secured to the inner surfaces of the fan cylinder walls. A cutting means is attached to the outer end of the longest fan blade and extends a short distance outwardly therefrom. Rotation of the fan causes the cutting means to trim the spacer panels to achieve the required clearance. A plurality of plastic sheets are secured to the spacer panels in covering relationship thereto.
