Perforated cylinders

AFT’s broad range of products, from conventional drilled cylinders to small-aperture, electron-beamed filter cylinders, enables us to provide the right perforated cylinder for your mill. And our ability to meet high-precision needs in drilling patterns, hole geometry and contour geometry allows you to specify exactly what you want. If your mill is not yet benefiting from the use of drilled cylinders featuring AFT Profile™ surface contouring, the opportunity for enhanced performance awaits.

The AFT Profile™ optimizes the performance of a screen by matching the contour style to a particular set of process conditions and application requirements. In doing so, it combines more than 100 years of manufacturing experience with state-of-the-art mill practices.

The AFT Profile™ offers:

• Improved efficiency
• Increased capacity
• Reduced fractionation
• Better runnability and pulp quality

AFT perforated cylinders are available with proprietary AFT Durachrome® protection, the highest quality chrome surfacing in the industry. A prerequisite to extended product life, chrome is evenly distributed by anodes designed specifically for screen cylinders. AFT’s in-house chroming facility and continuing develop-ment of superior surface treatments ensures the highest quality chroming and re-chroming services.
