aft slotted cylinder

AFT’s slotted cylinders are well suited for mills that require high cylinder strength and precise contour design in a one-piece screen mat construction. AFT’s line of slotted products — conventional slotted cylinders and high-open-area SuperFlow™ and LongSlot™ cylinders — feature the revolutionary AFT Profile™ for maximum capacity and efficiency. Yet another option is the AFT VariProfile™ concept, in which the profile shape in the upper half of the cylinder differs from that in the lower, enhancing performance by conforming to the changing nature of the pulp in the screening zone.
 
The AFT Profile™ optimizes the performance of a screen by matching the contour style to a particular set of process conditions and application needs. In doing so, it combines more than 100 years of manufacturing experience with state-of-the-art computational practice.

The AFT Profile™ offers:

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

All slotted 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 development of superior surface treatments ensures the highest quality chroming and re-chroming services.
